Billet Magazine Catch
The SI-XBC Extended bolt catch is a heavy duty, “go-fast” addition to the SI line of enhanced parts. Under high stress situations, the oversized bolt release lever aides in rapid thumb or palm engagement, even with gloved hands. The lever is reinforced for increased durability and impact resistance. Made from solid precision cast (not MIM!) steel, and hardened according to military specifications, the SI-XBC is a simple solution that ensures a lifetime of hard use. Strike Hard, Strike Fast, with the SI- Extended Bolt Catch.
The Strike Billet Magazine Catch Assembly features a billet magazine release button. Sculpted from a solid piece of 6061 aluminum, the button offers a functional and aesthetic upgrade to your AR. Deep serrations and ergonomic shape facilitates positive engagement and identification even in the dark or adverse conditions. The blind thread and color anodized options provide for a unique, custom look to your AR.
