DPMS AR-10 OEM Bolt Carrier Group Nitride .308 Win

DPMS AR-10 OEM Bolt Carrier Group Features The DPMS AR-10 OEM Bolt Carrier Group is built around a 9310 steel bolt assembly a steel alloy chosen for its strength and fatigue resistance under the repeated stress of locking and unlocking in a .308 Winchester chambered rifle. Extra strength extractor springs are fitted to help the bolt reliably pull spent cases from the chamber shot after shot reducing the chance of a stuck case or failure to extract. The bolt is nitride treated a surface hardening process that increases wear resistance and reduces friction compared to a standard finish which helps the bolt run smoother and resist galling over time. This combination of material and finish is aimed at long service life under the higher pressures a .308 AR-10 platform generates. The carrier itself is machined from 8620 steel and also nitride treated matching the bolt s wear resistance and corrosion protection. The gas key is nitride treated as well and properly staked using grade 8 fasteners a detail that matters because an improperly staked key is one of the more common causes of gas leakage and cycling problems in AR pattern rifles. Fitting this OEM specification BCG into an AR-10 restores factory level reliability without cutting corners on material or finish.
