TRIARC Systems .750 Easy Pin AR15 / AR10 Gas Block - OD Green

Streamline your custom rifle build and achieve a secure, "bombproof" barrel installation with the TRIARC Systems .750 Easy Pin Gas Block for AR-15 and AR-10 platforms. Designed to eliminate the hassle and precision risks of traditional gas block pinning, this low-profile component features an innovative pre-cut guide hole that dramatically reduces drilling time while protecting your barrel profile from accidental bit walk. Ideal for professional gunsmiths and home AR builders alike, the Easy Pin gas block ensures optimal gas efficiency and seamless clearance beneath modern free-float handguards.

Precision-machined from rugged 4140 carbon steel and in an ultra-durable olive drab green finish, this gas block is built to endure high firing schedules, extreme heat, and harsh environments. It features counter-bored pin holes for flush seating, dual serrated steel set screws to lock tight against set-screw dimples under recoil, and heavy-duty stainless steel coiled roll pins for both gas tube and barrel retention. Engineered to fit standard .750" barrel gas seats, the TRIARC Easy Pin Gas Block makes custom pinning achievable using standard 1/8" drill bits and everyday bench tools.
