Maybe a good book?

I've been thinking about a PTR-91 too. If you get time, I wouldn't mind hearing what you think of it when it arrives. Fit/Finish, Accuracy, Reliability. Oh and pictures. Lots of pictures.

I had a couple of HK91's, basically the same thing.

If you reload, youre going to want to get a port buffer. This family of guns is pretty brutal on the brass. Without the buffer, the case slams into the rear edge of the ejection port, and usually leaves a heavy dent in the case. The flute marks are cosmetic, and nothing to worry about. The buffer stops the dent, and redirects the brass more forward.

Personally, Id leave the trigger alone. They arent bad once you get used to them. I know a lot of people think otherwise though. If you shoot a revolver DA, youre golden. If your a SA fan..... learn to shoot DA.

Once you figure out the sights, I think youre going to like them. They are a little different, but I personally think they are the best "combat" sight going.

The big notch and the "globe" are your CQB/100m sight, you use the whole notch and the globe as the CQB sight, you use the small "V" in the base of the notch and the "post" in the globe for precise aiming out to 100m.

If you take a quick sight using the notch and globe, and then slowly roll your eye down to the small "V" and post, youll see they usually coincide.

The other numbered apertures are self explanatory.

If youre going to go the claw mount route, the ARMS mount is a better choice over the original HK type mounts, and about half the price. They hold zero like the factory mounts, but allow you to mount pretty much anything.

I always liked the HK web slings over most of the others.

Skip the sliding stock.

If you can find an oversize or winter charging handle knob, they are a lot easier to get a hold of than the standard "flat" type.

Heavy buffer to soften the recoil

I have the "GI" version of the PTR91. (I can't speak to other versions.)

The first thing that I didn't like about it was the plastic trigger housing. I replaced it with a metal housing that had been "clipped" to fit on the semiautomatic receiver (available from HK Parts.net). The internal trigger mechanism drops right into the metal housing with no problem. (You have to replace the selector lever with one with a shorter shaft.) But I encountered a problem fitting the new trigger assembly to the receiver. It turned out that the PTR receiver had four "tabs" or "standoffs," about 1/16" deep, on the lower edge of the receiver stamping. After I filed these tabs off, everything fit nicely.

You will probably be surprised at how much force you have to use to cock the gun. You need a strong left arm to use this gun!

I get 2.5MOA with surplus and cheaper ammo. I haven't actually shot high-quality stuff through it yet.

The rifle would not return to battery with one brand of ammo--Magtech, perhaps? It is cheap Brazilian stuff. It is way underloaded. I sold all of that stuff. Other than that, I have had two light primer strikes in many hundreds of rounds fired. That was likely the ammo (again, cheap stuff).

Fit is slightly awkward at times. My natural hold puts my cheek a little too close to the "bump" in the stock right under the sight. I have had my cheek hit with the recoil a couple of times. I'm also 6'1" with longer arms than usual. That probably isn't a problem with most. Or, I could be holding it incorrectly.

It is a little different than most rifles. There are some little things you'll need to get used to if you're used to ARs, AKs, SKSs, M1s, etc. Overall, I really like it. The FAL might be the only one I like better.

I always had my cheek right up at or on the bump, depending what sights I was using.

With a scope or red dot mounted on the claw mount, it was more up on the hump, which is an advantage to the stocks design, as you dont loose you weld as your head creeps up with optics mounted.

I think with most "combat stocked" rifles, your head should be down and forward on the stock, where you naturally have the sights appear when the rifle is quickly shouldered. The AK, AR's, and most of the others, work the same way.

Recoil's not bad, or any worse than an of the others of similar weight, but it does have a somewhat different recoil impulse than the gas guns do.

Port buffer.

Trigger job if the PTR is anything like the HK91.

Is that heavy buffer any harder on the weapon than the OEM part? Does it add much weight to the rifle? I didnt think recoil would be a prob on a 9.5 lb. 308

The heavier buffer softens the recoil a bit which is actually better for the weapon as the parts are not banging into each other as hard. HK91s & clones are well known for having sharp recoil compared to other self loading rifles

Recoil is not bad but if you can soften it for less than $75, why not do it? I have a heavy buffer on the way and will install it asap. So far, the two modifications I feel made the gun much nicer to shoot were: 1) increasing the length of pull with an extended butt pad and 2) sending the trigger group to Bill Springfield.

Let me add a comment comparing the PTR-91 (and any H&R design, really) with the FAL. I bought both guns at around the same time, so I didn't have any prejudices or preconceptions. I have to say that the FAL is by far the better gun, even though it's more expensive. To me, the FAL is "civilized," while the PTR-91 is "brutalist" or "barbarian." (Maybe the difference is in the Belgian vs. the Germanic cultures and mindsets.) Anyway, the experience in shooting them is different, and the PTR-91 takes more getting used to. This is a matter of the basic design, not the build quality.

So its a barbarians gun for somebody with a strong left arm... You guys are starting to sound like its made just for me!

"If you could pick among the various PTR91 models which one would you pick? What are your reasons?"

I went with the A3R variant through Atlantic Firearms because it has a sight rail welded on and a wide handguard. I was a little worried about the possibility of it being picky about ammo, but there have been no problems with well over 500 rounds down the barrel, including mixing steel case with brass. I've been happy with it overall.

I also just installed the heavy buffer before shooting this past weekend and will say that it made a slight difference but not what I was hoping for regarding recoil reduction. If the recoil isn't an issue for you, I would say don't worry about switching out the stock buffer. I'm recoil sensitive and, while it did make a difference, I may have entertained the idea that it would reduce recoil to a .243 level. Alas, it was not so...

It's a delayed blowback gun, a heavier sprint in the stock isn't going to slow down the bolt carrier's initial impulse from gas in the chamber. It has to unlock early to cycle and you will feel a two stage affect as it builds, releases, then bounces off the buffer.

The heavy action spring makes sure the bolt has enough force to chamber a round. Which means it takes more recoil to cycle it, unlike gas piston guns that can time a softer impulse. They also have a comparatively lighter bolt assembly. It was a general remark at gun shows in the 70's when I bought by first HK91 you could use the bolt carrier as a last ditch defensive weapon. It's massive and that contributes to the recoil. It took a heavy coat to keep the butt from striping my shoulder at the range with welts. Nature of the beast.

I hunted with it for 18 years, "accessories" was a joke in the day, it was a few HK parts or none at all. The ARMS mount was at least a big help, and finding a Euro handguard over the tropical model a nice touch. But, it's nothing like an AR for market support. At least the magazines are cheap now. Then, $40 for a 5 shot, $18 for steel, $25 for aluminum. Those are 1978 prices when gas was the outrageous sum of 75c a gallon.

I hunt with a AR15 in 6.8SPC, wouldn't go back for anything. The HK/PTR is the dirtiest rifle made, bar none, one round would filthy up the action worse than a magazine full in a M16. I was hunting with the HK and serving in the Reserves at the same time, and thought I had put money in a better rifle. About 20 years of that and I decided differently.

You didn't say if you had an intended purpose for the rifle ... this makes a difference in almost every accessory you listed.

Personally I like the HK E-21 machine gun stock which has the heavy buffer in it and port buffer to protect my brass as I reload.

Williams makes a nice set trigger ... For general purposes I like the military claw scope but there are any number of things you can do including welding scope mount tabs on the receiver for the ultimate solid mount which I've done in the target rifle on top.

Here's my little collection "91's" and they all have different purposes;

The top one started as a stripped SLG-95 receiver I built back in the late 90's, as a target gun which Murray Urbach set up the barrel, its my version of the PSG-1 and weighs in at 18 pounds

The center one is a genuine HK-91 which is pretty much stock, general plinker/shooter.

The bottom one is a Vector V-91P I picked up for my registered sear ... It's a fire breathing hoot.

i absolutely love my PTR91F. As mentioned before, get a heavy buffer and trigger job for sure. After that a cheek riser and claw mount!
