This is a now-discontinued PTR 91 KF featuring a 16" barrel and HK33 length handguard and cocking tube. The HK33 length handguard makes this PTR the perfect host for a G3K build, as PTR discontinued this particular configuration years ago. New PTR rifles with 16" barrels have the regular G3 handguard and are not G3K correct. The rifle features a 12 flute barrel made by Thompson/Center for PTR; the same T/C that builds precision rifles and pistols. The serial number puts this PTR as an approximate 2013 build, and has an FMP locking piece and firing pin.
This rifle is in excellent condition with exactly 10 rounds fired, which I shot to verify function and group size (~1.5 MOA). I bought this and put it away as a potential host for a build that ultimately didn't end up happening. This is perfect for someone who is looking for an almost-new G3K host rifle, or enjoy shooting rifles with unique or unusual configurations.
