Description
The LBE Unlimited Mil-Spec Bolt Catch Assembly is a complete bolt catch group for AR-15 and AR-platform lower receivers, manufactured from steel with a durable black finish. Built to mil-spec dimensions, this drop-in assembly provides reliable function for the bolt hold-open feature on semi-automatic AR-platform rifles.
This assembly includes the bolt catch, roll pin, spring, and buffer detent – everything needed to install or replace the complete bolt catch group in a standard AR lower receiver. The steel construction matches mil-spec dimensions for drop-in compatibility with mil-spec AR lowers, making it a straightforward replacement part for worn or missing components during a build, repair, or upgrade.
Made in the USA.
