The PTR PTR-91 A3SK .308 Win semi-auto tactical rifle delivers the accuracy and reliability of proven roller-delayed blowback mechanics in a compact, maneuverable platform. Built on the legendary H&K 91 design, this 16-inch-barrel rifle suits shooters who need .308 Winchester power in closer-quarters applications, from 3-gun competition to tactical training and home defense. The PTR-91 A3SK comes California-compliant with a 10-round magazine and grip wrap, making it ready to deploy straight out of the box for owners in restricted states.
At 9.3 pounds with a 38.5-inch overall length, this rifle balances authority with handling. The roller-delayed blowback system is inherently accurate and requires minimal maintenance compared to direct impingement designs—a real advantage during extended shooting sessions or when simplicity matters. The 1-in-10 twist barrel stabilizes .308 ammunition across the full velocity spectrum, and the 9- to 10-pound trigger breaks clean for combat-accurate shooting without creep. As a true semi-auto only, it's legal for civilian ownership everywhere and designed for hunters, sport shooters, and tactical training courses who respect the rifle's heritage and capability.
PTR Industries engineered the A3SK for shooters who want authentic .308 battle rifle ergonomics without the bulk of a full-length platform. Whether you're drilling precision at distance or running dynamic courses at speed, the compact format and proven operating system make this rifle a serious tool. California-legal out of the box—no additional modifications needed—and built to the exacting standards PTR is known for in the battle rifle community.

Roller-delayed blowback is inherently accurate and requires less maintenance than direct impingement designs. The system spreads recoil impulse more evenly, which reduces felt recoil and helps shooters recover quickly between shots. It's also extremely reliable in adverse conditions because it doesn't depend on gas tubes or pistons.
The 1-in-10 twist is optimized for standard .308 Winchester (7.62 × 51) across the typical velocity range. This twist rate handles common hunting and training loads reliably.
The PTR-91 A3SK is versatile: the .308 cartridge suits medium to large game hunting at distance, and the compact 16-inch barrel excels in tactical training, 3-gun competition, and close-quarters rifle courses. Many owners use them for precision sport shooting and home defense as well.
