The Sons of Liberty Gun Works Bolt Catch (part no. BOLTCATCH) is a replacement bolt catch built for the AR-15 platform, sold by Sons of Liberty Gun Works. It locks the bolt carrier group to the rear once the last round fires from the magazine, holding the action open for a reload instead of letting the bolt slam closed on an empty chamber. It also lets a shooter manually lock the bolt open for safety checks or maintenance by pressing it up while retracting the charging handle. Because it is machined to the standard AR-15 lower receiver footprint, it installs as a direct swap without any fitting during a build or upgrade. It is a functionally important part for reliable, correct AR-15 operation.
