The Luth-AR AR-15 bolt catch comes as a complete set with its spring, buffer and pin, so you have every piece needed to install it in a lower receiver (Luth-AR part no. LR11A). The bolt catch is the lever on the left side of the lower that locks the bolt to the rear on an empty magazine and lets you release it after a reload. Its small spring and buffer are easy to lose during assembly, which is why having the full set on hand saves a trip back to the parts bin. Luth-AR supplies parts for AR builders, and this kit is a simple addition to a lower parts order.

Key Specifications

• The kit centers on an AR-15 bolt catch, the lever that holds the bolt open on an empty magazine.
• A bolt catch spring is included to return the catch and keep it under tension.
• The bolt catch buffer sits between the spring and the catch, completing the assembly.
• The pin that secures the bolt catch in the lower receiver is part of the set.
• All four pieces come together in one package, so nothing has to be sourced separately.
