JP's full mass .308 carrier is designed to provide greater reliability in suppressed setups as well as SBRs and rifles without an adjustable gas system. Heavier than a standard DPMS LR-308 carrier, the JPBC-5 allows for the additional cycling delay required for reliable function in such setups.

Requires DPMS-pattern bolt, firing pin, and cam pin.

Specs:

• Large-Frame .308
• Stainless Steel
• QPQ Black Finish
