PTR 91 Field Strip (HK G3 Clone)

by Alex C.

The PTR 91 series of rifles are essentially HK91 clones that are built here in the USA on old Portuguese tooling. The rifles are priced right and shoot well, and many people are rediscovering the joys of roller delayed blowback as a result of their being on the market. So what do the guts look like, and how do you get to them?

    I had an HK-91 back in the late 70's. It ripped a case in half leaving the upper part stuck in the chamber. The roller lock is not my first choice for a 308 battle rifle but it was a well made rifle. Like most firearms in my past, I'm sorry I sold it. I would love to see a video replacing the rollers and head spacing. Another great video Alex,

      @Wolfgar They are known for rather high extraction pressure and violent extraction. I've never shot a roller locking weapon, but that trait would make me a little leery of buying one. I'm sure they work great with mil spec ammo, but I like my rifles to digest as many different types of ammo as possible. Easier on my bank account, and means I will be less likely to be left in the lurch looking for a specific type or manufacturer.

    I have a PTR 91 KF. I also have a SilencerCo 762 Specwar Suppressor that I have been trying to mount on my PTR. The SilencerCo 7.62mm Specwar mount and muzzle break is 5/8-24 threads steel AC591 (which I purchased from Cheaper Than Dirt). The PTR boasted its 5/8-24 threaded barrel on the web site for my model. The Specwar mount fits all of my 762 rifles with concentricity confidence. My PTR has two challenges. 1. The threads seem loose (wiggles) on the PTR barrel (more than on my other 7.62 barrels) until the adapter bottoms out. 2. The PTR barrel has extended machining to fit the OEM flash adapter that does not provide a sound barrel shoulder for a standard muzzle break to bottom out against or shim clock the mount and maintain concentricity. Is there an adapter or sleeve available to make the needed gap for barrel shoulder contact for a standard 762 flash adapter or another remedy or any advice for the PTR? Thanks
