Built on the AR-10 pattern, the PX-10 features an 18-inch 416R stainless steel barrel with a 1:10 twist to support a wide range of .308 Win loads. The mid-length gas system pairs with a 0.750 low-profile gas block for reliable cycling, and the threaded muzzle wears an A2-pattern flash hider.
The PSA X-10 lightweight free-float M-LOK handguard is approximately 15 inches long and includes integral QD sling sockets. Free-floating helps keep the barrel isolated from handguard contact, while the M-LOK interface provides versatile mounting for compatible accessories.
Receivers are forged 7075-T6 aluminum with a Type III hardcoat anodized finish. The flat-top Picatinny upper includes a forward assist and ejection-port dust cover. The rifle accepts LR-308/SR-25 pattern magazines and has a listed capacity of 25+1 with the included 25-round PMAGs.
The bolt carrier group uses a nitride-treated 9310, 7-lug rotating bolt and an 8620 carrier with a properly staked gas key. The action is semi-automatic, direct impingement. Controls include a single-stage trigger, a manual safety with SAFE/FIRE markings, a right-side magazine release, and a standard charging handle. Furniture consists of an adjustable stock (seller-reported length of pull 11-14 in) and a Magpul polymer pistol grip. Sights are not included.
