The SI-XBC Extended Bolt Catch is a heavy-duty, go-fast upgrade with an oversized, reinforced release lever for rapid thumb or palm engagement—even with gloved hands. Built from precision investment-cast 8620 steel and case-hardened to mil specs, it retains mil-spec engagement surfaces and adds a widened lower lever for easier manual locking of the BCG. Sleek SI styling fits forged mil-spec receivers and blends well with many billet uppers/lowers.
