LBE Unlimited AR Parts Magazine Catch Spring AR-15 20-Pack

The LBE Unlimited ARMCS20PK is a 20-pack of replacement magazine catch springs built for the AR-15 platform. Each spring is finished in black and cut to standard AR-15 dimensions, giving builders, armorers, and gunsmiths a ready supply of spares for new lower builds, repair work, and routine maintenance on AR-pattern rifles and pistols.

Offered under the LBE Unlimited AR Parts line, these magazine catch springs seat in the lower receiver magazine catch assembly and supply the spring tension that drives the magazine catch button. The 20-piece count is well suited to high-volume builders, warranty work, and bench stock for armorers who want dependable replacements on hand for stripped lower builds and parts swaps. Springs are a direct drop-in replacement for the standard AR-15 lower receiver.
