The iconic “roller-locked” series of rifles designed by Heckler & Koch (HK) have been a perennial favorite with military and tactical firearms aficionados. And, thanks to the efforts of South Carolina-based PTR Industries and its PTR-91 GI model, shooters have a chance to own a newly made version of this classic 7.62x51mm design.
PTR Industries rifles are based on a Portuguese variant of the HK G3 military rifle. The company acquired HK-licensed tooling from Portugal and shipped it over to the United States to allow the company to produce a U.S.-made (and legal) semi-automatic variant of the select-fire military rifle design.
While the company has developed a broad range of variants of the basic design equipped with collapsible stocks and Picatinny rail forends as well as 7.62x39mm and pistol versions, its GI model is designed to appeal to traditionalists as well as military history buffs. From its green stock set to its paddle-style magazine release, the GI PTR-91 looks like it has stepped right out of the 1970s and 1980s and into your hands.
Recent updates to the GI model include the use of an all-steel trigger group housing rather than a polymer unit as on the company’s other rifles. The lower is also marked with the original military rifle’s three-position markings for added authenticity (although the rifle remains a semi-auto-only design). Also newly added to the design is the use of 5/8×24” muzzle threading.
Fans of the design know its reputation for rugged reliability. At its heart a delayed blowback design, the PTR-91 employs twin “rollers” that lock into recesses located inside the rifle’s trunnion. The force required to unlock these from the recesses keep the action closed long enough for chamber pressure to drop to safe levels. The result is a repeating rifle design that does not feature a rotating bolt or gas system of any sort, and is renowned for working under a wide range of harsh conditions. The PTR-91 GI continues this tradition and wears a tough matte-gray Parkerized finish on its steel parts.
As with the original HK G3 design, the GI model is chambered in 7.62x51mm and feeds from a detachable box 20-round magazine (available in steel and aluminum versions). The overall length of the rifle is 40.5 inches and it features an 18-inch match grade barrel with an HK-style tapered profile. The rifle weighs in at a hefty 9.5 pounds.
