Product Description
The PTR A3S – 7.62×51mm Rifle is a full-length, semi-automatic rifle engineered to deliver roller-delayed performance with modernized features and enhanced durability. Built around PTR’s proven roller-delayed blowback operating system, the A3S provides smooth recoil characteristics and consistent reliability. The semi-automatic action is host-ready for use with NFA-registered auto sear packs where legally applicable.
At the core of the rifle is an 18″ stress-relieved, tapered contour barrel with a 1:10″ right-hand twist. The barrel is threaded 5/8×24, supporting a wide range of muzzle devices and suppressors. A welded 7.5″ steel Picatinny rail is integrated onto the receiver, allowing direct mounting of modern optics without the need for high-offset scope adapters, improving ease of setup and hit probability at range.
The PTR A3S is equipped with a heat-treated full-auto profile bolt carrier and a paddle magazine release, enhancing durability and ease of operation. The overall finish consists of powder coating over Parkerizing, providing increased corrosion resistance and long-term wear protection while maintaining a professional matte black appearance. A slim-line polymer handguard completes the forward profile, offering a comfortable and functional grip surface.
Measuring approximately 40.5″ in overall length and weighing 9.5 lbs unloaded, the PTR A3S feeds from 20-round aluminum magazines and features a trigger pull set between 9–10 lbs for consistent operation. Each rifle ships with one original surplus magazine rated Good or better and includes a cable lock. The PTR A3S is available in standard, California-compliant, and Vermont-compliant configurations.
Within the PTR lineup, the A3S occupies the enhanced modern .308 rifle segment, offering roller-delayed reliability, integrated optics support, suppressor-ready barrel threading, and durable construction for users seeking a full-featured, full-length rifle platform.
