'splain me the fnh and 5.7x28

[Big Gay Al]

Many many moons ago, when I worked armed security in the Chicago area, someone with a bad sense of humour (and a bad choice of weapons) took a few shots at me with an AR15. This was aimed at me through two glass doors. The rounds penetrated the first door, but completely fragmented after passing through, and never touched the second door. Needless to say, I was a bit surprised, AND, thankful they didn't use something like a .308 or .30-06.

Unfortunately, the rounds so completely fragmented, the police couldn't tell what they were, only the shell casings left outside told us it was 5.56mm.

So I have to wonder, would the 5.7 round act the same?

Were they shooting with some sort of soft point round or something similar? I've seen both M193 and M855 do quite a bit better on barrier penetration than that. Not the strong point of the 5.56mm round, but I've still seen both rounds make it through two car doors and put neat, round holes in witness panels three yards on the other side of the car.

The police couldn't be sure. Like I said, the rounds fragmented so badly, we didn't know the caliber until we found the shell casings in the driveway.

But the best guess was they were using hp or sp type ammo.

And these glass doors were THICK. Over half an inch.

Too much headaches. An AR pistol shooting .223 or a .22 magnum seem to be a better option.

you think the 5.7x28 pistol is louder than an AR pistol shooting .223 ???

The Rheinland Arms upper? Was it the one that used P90 mags and ejected down the magazine well?

How'd it look/function?

I didn't see it shoot. It was hanging up on a pole with a sign under it. It looked as though the mags would be the same size as the regular AR mags. From a distance you would have thought it was a normal AR. You had to walk up to it and read that it was for 5.7x28. So I don't think it's the upper you're thinking of. This looked as though it'd function like a normal AR mag wise and ejecting the brass wise.

yes I have fired a Carbon Fiber AR pistol and my 5.7 USG at the same time. Although my hearing is not the best anymore the 5.7 had a louder sharper shorter crack. All I can figure is the 5.7 designed for short tubes has hits its power peak almost instantly hence the blow back operation and the 223 designed for a longer tube most likely has a slower burning powder.
I will have to look up the SAMMI limits for the 2

Weird.

I think there's also a variant that takes Five-seveN mags.

Also, it's Rhineland Arms; sorry for any confusion that misspelling might have caused.

AR-57 link.

 

[loki.fish]

That may be it Stiletto. It looks very similar and I just noticed the PS90 mag sittin on top of it. I may have been on the one I saw, I didn't pay that much attention to it. IIRC the price was about $695. It may have been $595 though. Thanks for more info on the thing. I had been wondering about it, but not seen anything about it other than at the shoot. And there wasn't much info there about it.

 

[sinistr]

another plus to this pistol is the weight,you barely notice carrying it in a kydex iwb.it also has an ambi safety and mag release.

 

[panzermk2]

I am holding out for Rhineland's carbine that takes the handgun mags. I like haveing a pistol/rifle combo useing same ammo and mags.

The PS90 is out of reach due to cost

Hey, Big Al. Be glad it was a 5.56 and not a 7.62x39 spittin' kalashnikov. Or else you might not be telling the story about it now. As for the 5.7, I'd have to wonder how it would do against the human body when it comes to bones and what not. Personally, I'm with anybody that says there are better weapons to spend $900 on. Not to say that you're stupid if you bought the gun, I'd just rather have something else. Like a decent autoloader or revolver in no less than .38 special or 9mm. And I'd still have enough money to get a nice plain-jane Remington 870 with extended tube or Mossberg 500 with the same. And buy ammo for both. Not to mention have no problems acquiring ammo for both just about anywhere you go.

 

[Stiletto Null]

panzermk2, sounds like you want the Ranger. Dunno if they're actually out on market yet.

 

[panzermk2]

the G5 is the one I'm holding out for

gander mountainhas ss195 and ss197(40gr hornady vmax blue tip) for 19.99 a box of 50. 40 cents a round. not too bad. i know that it will stop a possum and a copperhead real fast. i use my 57 for a yard gun. really light and 20 in the mag. sometimes i carry it but it is a big weapon and not the easiest to conceal.

I think the jury's still out on the effectiveness of the round. However, its nice to see some innovation on the part of the firearms industry to try to deal seriously with the idea of recoil in combat handguns. A lot of people don't like to bring the topic up because of the macho factor of guys being convinced they can control the more brutish cartridges as a point of honor.

ReedsAmo is also making small fast amo, and barrels/uppers for
.22 reed express -- very similar concept.

They say that that ammo fired from the
same lenght barrel
as FN five seven --
can push 40 grain bullet
at the same speed as FN can push 27 grain bullet

I just asked them yesterday if they are working on Barrels/uppers for
Glock 20,
EAA witness and AR15
(they already have barrel for cz-52)

they said :

The .22 Reed Express has already
been built and tested 100% on an AR-15 platform, the 1911 we are working on
as well as the M9.
