My PS90 review with lots of pics!

The PS90...

As popular as this gun is, it receives allot of resistance.

The plastic sci fi movie inspired spacegun has allot to prove of itself in the civilian world. Just what is it good for? What does it do that other guns dont?

P6140060.gif

Before we venture further, I must confess I have wanted this rifle since I was 16. Oh no, I had no plans of aquiring one. In 1994 I had more concern about super mario bros than the federal AWB. When rumors trickled in that Fabrique Nationale was to produce the weapon I once though was unatainable... I went ballistic. Well, I sold, traded, and worked my way to taking home a PS90 in three layaway payments.

P6170101.gif

I had her... I am still in shock that the one weapon I have wanted more than any other is in my possesion. After handling her and shooting the weapon, I am just as excited about the system as I was six years ago. Lets find out why:

P6140062.gif

The weapon breaks down into the receiver, bolt, clamshell stock, and FCG.
The weapon breaks apart at the push of a button. Basic cleaning of a firearm can't be much easier than the p90. From what I gather, the bolt never contacts the sides of the plastic receiver. The two guide rods fit into two set of holes adjacent to the barrel. In the rear, the guidrods merge to a very tough recoil buffer with a peg in the end. This peg slides directly into the guns rubber butplate and traps it. The buttplate cannot be removed untill the bolt group is slid out of the weapon.

The FCG is removed via a lever system and slides out the rear of the weapon. Everything in the FCG is plastic minus the rollpins and a mystery part in the rear. We won't talk about the mystery part cause its function is a mystery.

P6140059.gif

The weapon also features a set of iron sights adjacent to the reflex sight on both sides of the weapon. Totally non-adjustable. The reflex sight itself has a very small feild of view, and the circular reticule isn't the fastest think to pick up when looking into a well it area from the dark. However, it appears to be paralax free. The light collector also collects ambient light from the front and rear of the optic. Light gathered at the front illuminates the circular reticule, and light from the back illuminates the T post. The rear T post is powered by tritium at night, and the tritium can be seen in the darker picture below.

Lets get on to what I really want to talk about. Shooting the PS90 is amazing. It has become my favorite firearm in a single shooting session and will continue to be unless I start finding reliability problem. The first session gave me trouble free shooting from the first round to last. My favoritest (hehe) thing about the P90 must be its handling characteristics. The weight of the weapon is definatly behind your trigger hand. This rear weight makes the rifle really quick to shoulder and move about engaging targets. It can also be shot one handed very easily since the weight is behind your hand. I need to mention that the rifle is absolutely tiny. Several inches shorter than an 16 inch AR15 with a fully colapsed stock. Much more comfortable to shoot than an AR15 with stock fully collapsed.

I really like how fast the weapon is. The optic sits at the perfect height for *me* and I can engage a target very quickly. That rearward weight coupled with a optic that sits at the perfect height for me makes this the fastest weapon I own. I can shoot with my head erect and don't have to tilt my head down like I do with my AR15s. It is also very forgiving about where you put your face. Most users will have their face pressed against the radiused edge of the 50 round magazine.

Now being so fast on target is good, but being fast with mutliple shots is even better. The PS90 doesn't recoil so much as it burps in your hands. You can simply send round after round towards your target with alot of control.

I also find the weapon is just darn fast in my hands. Fastest gun I own, and that keeps me excited about a firearm. YMMV

Now what kind of nitch does this thing fill? What can you do with it?
Well, it is an uber tactical small game gun. Small game simply doesn't stand a chance, so I guess you can file the weapon under the fuzzy small animal killer category, but... it was designed as a weapon of personal defense.

Well... You have fifty rounds of low recoil ammunition. Thats great, the more bullets the better. Small bullets? Yes, they are small, but lets keep going. YMMV but this is my smoothest weapon to shoot. I am simply faster with this weapon than any other in my household. Fastest on target, fastest putting multiple rounds on target. I would imagine that getting the first shot on an adversary is pretty important. Hitting COM before the other guy can return accurate fire is a real possibility with the P90... at least in my eyes and hands I guess. This may not be a one shot one kill kind of weapon, but you can have two rounds on a target in the literal blink of an eye. It fits *me* so perfectly that all I have to do is look at my target with my head erect (read, normal position), slap the side of my chin against the mag, and the white dot is on target. Thats what blows me away about this gun.

Yea, it's not shooting 50 action express, but it isn't shooting a 22LR either. Would I use it to defend myself? I wouldn't feel naked, that's for sure. I do like the ability to shoot through objects though, something this little gun would have trouble with.

Am I being fanboyish about this weapon? Has 6 years of wishing blinded me to its faults? No. I realize that its biggest fault (and hotly debated issue) is the weapons proprietary ammunition. I have heard everything from wounding that rivals +p+ 9mm loads, to anemic performance. I don't have the answers... and wont have a definite opinion until I shoot a few critters.

Hope you enjoyed my review!

Faults:
The sight washes out when looking outdoors from inside.
Sight has a small FOV (though this doesn't seem to affect *my* speed)
The weapon is also a bit slower to reload, but speed comes with practice in all things.
Some users are getting their FCG mauled by brass. My P90 hasn't displayed this problem.
Expensive ammunition.

Bonus:
Light and handy. Very small weapon.
Large magazine capacity.
Ergonomics are very good, very comfortable gun.
Low recoil, and fast speed to aquire a target.

Excellent review & pics, thx! I recently picked up a couple of PS90's myself and am still amazed at how fast & easy they handle (and this from a guy who's never liked bullpups). I agree the factory ringsight has a small FOV (doesn't bother me) but the tradeoff is superb SA. Accuracy? If I do my part then 3-shot .5" groups at 50yds are common even w/the typical bullpup trigger linkage. I was also surprised at the mild report w/no discomfort at all if fired w/o hearing protection (was a test only, otherwise I always use hearing protection). The PS90 is a PDW, not an AW, and IMHO serves well for the HD role since you have a very high capacity magazine, very low recoil, short AOL for manuevering and a bullet that's unlikely to exit the target or overpenetrate to endanger the neighbors. To prevent any brass damage to my FCG I simply applied a little soft velcro to the impact points. Keep us posted!...

Well, I'm a bit older than you but I've always been a fan of Stargate SG-1, since its beginning:D

So, when I herad these were finally gonna be available I was really interested. I'm also one of few who like bullpups.

I got to fondle one at a recent gunshow (but not for long, there was only one there, and there was a long line!). It felt awkward at first, but I think that's just becasue its so different. But I could see that it would be easy to get used to it, and as you mentioned it's just about as compact as a rifle (even though you could argue it's really a pistol caliber, or at least in that class) could possibly be. Especially with a 50 round magazine.

Sadly, it'll probably be a long time before I can afford one:( , but its near the top of my list of "gotta have one" items.
 
Nice writeup. CDNN is offering a black stocked one for free with purchase of a large pile of other FN shotguns,rifles, and handguns. So if you have a new credit card burning a hole in your pocket... I would like one of these two but the cost of ammo is holding me strongly back. And the drive to get all debt down to around $0!

http://www.cdnninvestments.com/dowournewcat.html
 
Yea, I saw the CDNN deal last week when the catalog came out - ya gotta buy a lot of stuff, though :uhoh:
 
Get two of these puppies, one in each hand.:D The ergonomics on the P90 just begs for one-handed shooting.
 
That was a very thourough and thoughtful review, and I'm glad you like it. I had a little different take. While I do like bullpup guns, I had only a lukewarm interest in the P90. Then I handled one and decided that $1,700 was better spent on other things. What didn't I like? Well, for starters, the machining on the reciever was a bit rough for a four-figure gun. Also, the PS90 is awefully heavy for a compact weapon firing a low power cartridge. As we all know, magazines and ammo are spendy. I found that the sight system was difficult to use when transitioning from different lighting. The grip is thick and short and the angle a bit unnatural. It is similar to a conventional rifle stock, but positioned differently to the shooter, lending itself to an (IMO) unnatural feel.

I think the biggest detractor is the ballistics vs. platform. Energy figures in the mid-300 to 400 ft/lb arena are fine for handguns, but anemic for rifles. I can see the benefit to rear echelon being armed with it's FA counterpart-at (1200 RPM, IIRC) in a 7 lb gun, recoil is the enemy and the 5.7x28 allows for controlled fire. But in SA, substantially more recoil is perfectly acceptable and the .223 rem. has low recoil anyway, despite offering more than 3x the power from a firearm of similar weight aand marginally larger dimnsions. And, of course, there are .223's (conventional and bullpup) that weigh similar or less.

There does not seem to be sufficient data to determine whether the 5.7 is better, worse or on par with handgun ammunition used in SMGs fulfilling similar roles, but there is no doubt it is not nearly as effective as assault rifle chamberings. It should have an edge in armor penetration over pistol rounds, especially at range, but the question remains if it is capable of incapacitating (especially after defeating armor).

I think for folks who like the PS90 it is largely a visual attraction and the wow! effect, since they are such strange little critters. This is not to say that it is a lowsy weapon, but it is definitely going to have limited sales.

Who knows, if I end up with enough money that I won't miss 2 grand I might get one. But for now there are about 8 dozen ahead of it on my list.
 
Nintendo 64, Bond, RCP90...

Back in the early 2000's, nothing beat playing Bond with friends and writing your name on the wall with this little bugger after hosing him with mag:D . In semi auto, with the obnoxiously long barrel(could be sbr'd though), at 1700 bucks, and not the 1700rpm version:)banghead: stupid NFA), I will have to pass for a while... Now the S2000 seems interesting, but again, it doesn't do anything my M4gery can't, so what I'm after is a M14, FAL, or Garand first:).
 
As a Stargate SG-1 fan, I looked forward to the introduction of a civvy-legal version of this little subgun.

Last month I had a chance to handle one at the Austin gun show - asking price was around $2k, about $500 over MSRP of $1513.

My impressions from < 1 minute of handling it . . .

1. It was heavier than I thought it would be . . . the extra weight will steady the gun when firing the subgun version, but IMHO it's not as useful for the SA civvy version. Still, even with the extended barrel, it's pretty compact.

2. Unless it is a subgun, I'm not real enthusiastic about the cartridge . . . it's really not that different from a .22 Hornet, and that's not a round I'd deliberately choose for defensive use, regardless of bullet type.

3. The sight is a wretched POS . . . dim, like looking through sunglasses.

4. From the way the PS90 is put together, I really don't see why MSRP isn't more on the order of $700 or so. I guess FN figures they'll be able to pocket an extra markup from sales thanks to the TV show tie-in "cool" factor.

5. I choose to spend my "gun money" on something else.

YMMV.

(BTW, the latest American Rifleman reviews some FN rifles, including the PS90.)
 
A $700 dollar MSRP? I know you are being sarcastic, but the weapon isn't an open bolt SMG.

The reflex sight is very fast. I can aquire it more quickly than I can any ironsights. Small FOV and washout are the biggest problems. Its not the best, but I put the stock optic on the p90 on the same playing feild as traditional iron sights. I know, you are going to say that you can't use the p90 very well from indoors to out, but then again... you can't use Iron sights as fast when it s really dark out can you? P90 has a nice tritium illuminated reticule that covers that area. All in all, I am pretty neutral with the stock optic. When in the right conditions, it's way faster than irons. I don't think its a "wretched POS".

Im not going to try and defend the 5.7x28 because I haven't got to shoot any small game with it yet. I might try a small animal. The round is, for all intents and purposes, a weakly loaded .223.
Supposedly, out of a p90, the round penetrates 12 inches, with kevlar, 9.25 inches.

Ill continue this later! Gotta go!
 
Well I, for one, think it's a very cool little gun. Considering how much I shoot, I would prefer one chambered in 9mm or .223REM. (I know .223REM isn't realistic with the way the mag feeds...but it'd sure be cool!).

I'm going to stick with a home-built AR-15 for my first carbine. But the PS90 is definitely WAY up there on my "evil guns I'd love to own" list. Right up there with the Steyr AUG, H&K MP5, and H&K SL8.
 
My auto-electric Airsoft copy completely sold me on the ergonomics. I wanted to skirmish with friends, and I wanted "one Airsoft" that was quality, and handled well, and didn't want to "collect them all" because I had plenty of real guns.

A friend who owns a gaming/adventure store put me onto the P90. I figured with the AWB I'd never own one, so it would be perfect to see what one felt like, and how it handled in fluid moving situations.

And while the weight, recoil, nor the report were there, I'll second Knife_Sniper's experiance. Fast, fast, fast, fast! The P90 platform is a born pointer. I've held nothing that manuvers or handles like it. Trying to run around, crawl, and take moving shots with an AR seems like trying to cuddle with a cactus in comparison. (And I like the AR, when I say that, AK's feel like a rusty car muffler...)

The real verson is obviously heavier, but it shoulders and tucks into "the pocket" like an extension of your body.

The horizontal magazine seems ungainly at first, however I can't think of any other rifle or carbine that can be reloaded while remaining perfectly prone to the ground, and lets you stay on target.

Whoever came up with the P90 at FN Herstal is an ergonomic genius.

If they'd only made it in .223, or even .30 carbine. :( Like so many others, the 5.7 is the one part of the equation I don't have complete faith in. As a civvy shooter, I need a carbine like the SP90 to fulfill a few different needs to justify it's expense.

From the military PDW standpoint it makes perfect sense, something just deadly enough to keep the enemy at bay while the calvary arrives, and high capacity, flat trajectory, high ROF, and low recoil impulse to make darn sure the enemy keeps thier heads down, but at $1500 MSRP and $2000+ street, I can't justify it yet.

My one complaint is that I too was very dissapointed in the reflex sight of the model I handled at the NRA convention. It just didn't function well in a well lit indoor situation, and the narrow field of view was limitng. Something like an EOTech, large Aimpoint, or Bushnell Holosight is needed.

I am waiting for the flattop Picatinny rail version to come out, and the price to reach some semblance of sanity before I'll consider buying it.

But color me interested, very interested.
 
The PS90/5.7 combo is a niche system. It's not an AW nor was it designed to be (it's a PDW, designed to CYA while you E&E). However, as mentioned earlier, it's *very* fast, short, lightweight, ergonomic w/very little recoil/recovery time, easy to fire/swap mags while prone, very high capacity mags and can be fired effectively using the factory optics w/one hand. Since overpenetration isn't likely it's an excellent candidate for the HD role, IMHO. Yeah, I'd like to see the price come down by $500+ and more reasonably priced ammo (Wolf is supposed to introduce their 5.7 load later this year) but I have to admit I'm taken w/the PS90 like no other rifle or carbine (w/the possible exception of my .308 Dragunovs). No, it's not for everyone and I'm not going to try convincing anyone that it is. However, at less than 200m I don't think I'd like to be on the receiving end of the PS90...

.

That's giving the 5.7 a lot of undue credit. Tests with commercial ammo in the PS90 put the 40 gr. loads out between 2000 and 2100. 40 gr. loads leave my 20" hornet at 2833 FPS avg. Account for the longer barrel and you can subtract about 100 FPS for a fair comparison. That still puts the Hornet a solid 600 FPS faster than the SS197 SR (the warmest 40 gr. 5.7 load). This equates 68% more power. The 5.7x38mm is much closer to a .22 magnum (many .22 WMR loads are listed in the 350 ft/lb range, leaving them only about 10% less potent than the 5.7x28). This was actually the first thing that came to mind when I looked at a Five-seveN pistol and remembered the ballistics-I thought "I'd rather have the old Grendal P-30"; similar power with 10 more rounds.

The other issue is the fact that ~2000 FPS is the threshold between pistol-type wounds and rifle wounds. With the 40 grain loads, the PS90 is not going to demonstrate rifle-like wounding capability. Perhaps the idea was to merely inflict handicapping wounds. I don't know, but I'd gladly trade a little less magazine capacity for a more effective weapon.
 
I think it would be a cool gun to own. Someday I'll get one.


How is the trigger? Do the mags have issues, when dropped loaded? I heard the mags had some problems.

the 40 grain loads are SR which means sporting round. i'm fairly confident they weren't developed to merely inflict handicapping wounds, as that isn't terribly sporting.

the non-sporting rounds (ss190/192/195) use much smaller and faster 28g - 32g loads. granted, even those speeds (2500 and change) aren't going to match the hornet's, but really, what do you expect when comparing a cartridge made for an automatic handgun to a cartridge made for a bolt-action rifle? that's like being surprised you can shoot a 223 Rem faster out of a bolt gun than an AR15. duh.

seriously, how many subguns do you know that shoot rimmed cartridges?

one advantage that hasn't been mentioned yet is that 55g bullets loaded in 5.7x28 are subsonic. the ps90, with 10" barrel and suppressor is an awesome setup.
 
A $700 dollar MSRP? I know you are being sarcastic, but the weapon isn't an open bolt SMG.
Neither are AR15s, and they don't go for much more. DSA STG-58s can be had for well under $1000. Beretta's 9mm carbine is down around $500. A CCU for a Glock will run you about $800 . . . including the Glock. So $700 MSRP really isn't out of line, IMHO.
All in all, I am pretty neutral with the stock optic. When in the right conditions, it's way faster than irons. I don't think its a "wretched POS".
So if you use it in a personal defense role, just be sure it's "in the right conditions." ;) As my original post stated, YMMV . . . to you it's not bad, to me it is a WPOS. Fine - opinions vary.

I stand corrected.

So one can get a Ruger 10/22 Magnum with nearly identical ballistic performance, though not the "cool" factor or the 50 rd. mag . . . but with MUCH cheaper ammo . . . hmmm . . .
 
The more I see and handle these things, the more and more I really want one. Not sure what I'd really do with it at this point, but it would be pretty darn neat to have either way. I would love to be able to put a few rnds through one before buying one though.

Similarly, I have to use Iron sights in the right conditions... or I can't see the front post!

____________________________________________________________________________________________________________

I was looking up data for 22 WMR... This is the *hottest* load I could find: OSSI +P

OSSI WMR: 35 Grain VMAX @ 2250 FPS at 393 Ft Lbs from a 20 Inch Barrel

SS197: 40 Grain VMAX @ 2100 FPS at 391 Ft lbs from a 16 inch Barrel

SS195: 28 grain JHP @ 2500 FPS at 388 Ft lbs from a 16 inch barrel

The average speed for non +P WMR was:

40 Grain @ 1910 FPS at 325 Ft lbs from a 20 inch barrel.

I used:

Mass x Velocity ^2
------------------
450240

WMR has the advantage of a 20 inch barrel in these tests. What would it look like if we gave it a 16 inch barrel like the PS90? The +P OSSI would be a tad weaker than either 197 or 195. The normal 40 grain WMR ammunition would be around 250 Ft Lbs out of a 16 inch barrel if the 50 FPS lost per inch of barrel rule is applied. If anyone has a good average speed for non +P WMR out of a 16 inch platform, please post it. I am curious as to what it can do with 16 inches of barrel. My data in this paragraph is just an estimation of what a 16 inch can do with WMR.

I got my Rimfire data here: http://www.korabrno.cz/bal-22.html
I did not use their FtLbs calculation, I opted to use mine on all the comparisons above to make sure everything was uniform. I utilized their speed and ammo weight. I also calculated out the 5.7 with only the speed and weight of the ammunition.

My view of the ps90 Rifle

First let me say that I've been caught, hook line and sinker by both stargate shows. Not so hard to understand when I'm also old enough to be one of the first trekkies. Was also a big X-files fan, and sorry to see it end. And now stargate SG1 is ending, what's this world coming too. Anyway I've been a gun collector forever. I have always collected the guns that I saw as the guns of the future. The space age looking guns, made from space age materials. I've had them all at one time or another. AR-15, Ak47, uzi, FNFAL, HK mp5, styer-aug and a host of others. I've spent thousands of hard earned dollars on this wonderful sport of gun ownership, as a free born American, in the greatest country in the world. But nothing has giving so must pleasure and fun as my ps90. Shooting it is a dream. It never fails to chamber, or eject, and what a breeze to take apart and clean. AS for the rounds it is the perfect round in my opinion. During the last months of WW2 the german army was testing a new secret rifle and cartridge in the field against the Russian. The first magazine feed assault rifle, with a 30 round magazine, and a new bullet the 30 kuzt. It was tearing up the Russians in combat, and the Russian made every effort to capture one of these secret rifles. They did and created their own version of the german rifle, the ak-47 rifle with the 7.62x39 bullet. The germans had come to see that the battles they where having in the field were not the 1000 yards battles of WW1, but rather about 300 yard. So they invented a short range bullet for that range. By making it smaller they could carry more ammo in the field. America was slow to hop on the small bullet band wagon. We still had tons of good guns sitting in warehouses to use. Then came Viet Nam, or The Nam to those who where there. The battle field got smaller again, about 100 yards max. So along came the M-16, and the 223 bullet. You want a lot of ammo in the jungle when sometimes you are less that 30 yards away from those who are shooting at you. The 223, after the bugs were worked out was one of the best bullets ever. It really did the job. I myself have shot several whitetail deer here in the northeast in the last 30 years with my ar-15, with perfect one shot hits each and every time. The deer here are about 140lbs on the norm. I have shot two russian boar, and several coyotes, with no problems at all. Bottom line YOU MUST PLACE A PERFECT SHOT. So get out there and practice, cause if your a bad shot a 50 cal. machine round won't do the job. Now we come to the lastest space age round. The 5.7x28mm. One of the benifits of being and old fart is years of knowledge under your belt from just being alive. We have had some great men who are no longer with us, who 40, or 50 years ago did a lot of wildcating with different bullets. And I base all my knowledge on their hard work, now long forgotten. I heard a lot of talk about the 5.7x28mm being a poor round like the 22 hornet. Well I think it is just like the great hornet but better. The hornet rifle about 50 years ago was one hot round with shooter's on a budget. It has taken some great animals let me tell you. Here are just a few. Whitetail Deer, Black bear, brown bear, wolfs, moose, coyotes, fox, squrriels, wild boar, cougars, praire dogs, groung hogs raccoons, and the list goes on. AGAIN YOU MUST PLACE A PERFECT SHOT. But if you can't then don't use it. The bottom line is this, if you are looking for what I consider to be the perfect survivial rifle to protect you and your's, and put food in the pot you can't go wrong with the ps90 and its bullet. I will keep you updated on this rifle and round, for I'm going to use it hunting this year. See you soon.
 
Two things:
1). 5.7 is a decent round if you can use the ammo that it's designed to use--basically, all the ammo the ATF banned for civvie use, leaving behind an anemic .22 WMR.

2). Knife Sniper, water your plants. That one in the 5th picture down is pretty far gone.

Nice writeup. I hope you're this thorough on all your guns, so we can learn without spending the cash ourselves! :D
