LBE Unlimited Mil-Spec AR Bolt Catch Assembly, Black Steel

The LBE Unlimited Mil-Spec Bolt Catch Assembly (LBE Unlimited part no. ARBCASY) is a black steel, complete bolt catch kit built to Mil-Spec dimensions for standard AR-platform lowers. LBE Unlimited packages the full assembly rather than just the catch lever, so a worn or missing part doesn’t leave you hunting down small hardware separately. It’s a straightforward way to finish a new build or restore a bolt catch that’s stopped holding the bolt open reliably.
