First ive ever heard of a PTR-91. Please share the specs with us.
it's a 18" fluted chrome-lined barrel chambered in .308. i've got a standard 2 point sling on it, a stubby vg, harris bipod, a tacforce flashlight with a pressure pad zip-tied to the vg, a length of pull and cheek well adjustable butt-stock, picatinny rail covers and a 3x9 luminated scope with a red dot laser.
Off shoot of the CETME
For a second i thought it was a copy of the PSG-1 then I looked at it closer and yes it looks a lot like a CETME .308.
