Description
The LBE Unlimited AR-15 Bolt Catch Plunger is a small but critical lower-parts component for the AR-15 platform, offered here in a 20-pack for builders, gunsmiths, and armorers who want a ready supply on the bench. Each plunger is machined from 1117 steel and finished in black for a clean, mil-spec appearance that drops right into a standard AR-15 bolt catch assembly.
The bolt catch plunger sits inside the lower receiver behind the bolt catch roll pin, providing the spring-loaded detent pressure that lets the bolt catch hold the bolt open and release it on demand. LBE Unlimited machines these plungers in the USA to consistent dimensions, making them a reliable replacement for worn or lost originals during a build, repair, or refinish.
This 20-count format is ideal for armorers keeping an AR workbench stocked or for shops working through multiple lower builds. The plungers are compatible with standard AR-15 bolt catch assemblies and are sold as a 20-pack of replacement plungers only.
