White Label Armory Bolt Catch Detent Spring AR-10/AR-15 Silver 10 Pack

The White Label Armory Bolt Catch Detent Spring is a mil-spec small-hardware component built for AR-10 and AR-15 pattern rifles. This silver spring is precision-made to military specification tolerances so it drops into the bolt catch pocket with the same geometry as the original factory spring, keeping the detent under proper tension for reliable bolt catch function.

Whether you are completing a fresh AR build, refreshing a well-used lower parts kit, or simply keeping a few spares on the bench, this 10-pack gives you plenty of replacements for the AR-10 and AR-15 platform. White Label Armory sources its springs from American manufacturers and builds them as part of a full line of mil-spec pins, detents, and springs for the modern sporting rifle.

Each pack contains ten bolt catch detent springs in silver finish, ready to install during a lower assembly, a parts refresh, or general AR build work.
