Precision machined from 7075 T6 Forgings, this extension adheres to correct Mil-Specs, providing exceptional strength for scenarios like drops or malfunction clearance drills. Fully assembled with a forward assist and ejection port cover, it features a Mil-Std 1913 Rail for optics and accessories. Designed for M4 barrel extensions, it boasts laser-etched T-markings for optic remounting. The Mil-Spec forward assist comes with a heat-treated tool steel pawl, press fit, and pinned cap. With a hard coat anodized finish per Mil-A-8625F, Type III, Class2, and dry film lube on the interior bore according to Mil-Specs, this BCM® product is made in the U.S.A., ensuring top-notch quality. Additionally, users are advised to use a heat gun or hair dryer if the threaded bore of the receiver needs warming for a tight barrel extension fit.
