The PTR91 F is a semi-automatic rifle chambered in .308 Win. or 7.62 NATO. PTR91 is the name of both the manufacturer and its product. The company says it wants to build a quality rifle based on Heckler and Koch’s G3 rifle because after HK stopped production of the G3 poor imitations popped up. What PTR says they do differently is they use designs and parts directly from HK.

There are several variations of the PTR91, but the standard models are listed as PTR91 F or PTR91 C. The main difference between two is that F has an H&K pre-ban style flash hider, which does as described–hides the flash–and the C has a compensator welded to the barrel, which cuts down recoil. Also, C can be sold legally in MA, CT, NY and NJ.

The PTR91 has a recoil-operated with a delayed roller-locking system. So after the firing pin strikes the primer gunpowder burns, gas expands and propels the round out of the chamber–just like any gun. As it pushes forward it also pushes back on the bolt causing recoil. On both sides of the firing pin are rollers that roll with the bolt as it is pushed back. The rear of the bolt will catch on the bot housing and, at this moment, the rifle ejects the spent casing. Also, at the rear of the bolt is a spring that compresses as the bolt is pushed back. Once the bolt catches, the spring reverses the force and sends it forward in turn chambering a fresh round. The rollers are supposed to help the bolt travel with greater speed.

Features include a rear sight that’s adjustable for windage and elevation. A fixed front sight. It is drilled and tapped for rails. Its 18″ steel barrel has black nitride treatment, which hardens the metal.

PTR91 Inc recommends its rifles for precision shooting, military and law enforcement use.
