Gun Engineer Buffer Retainer And Spring for AR-15

The AR-15 Buffer Retainer makes it possible to break your rifle down without the buffer and spring shooting out. The buffer and buffer spring are housed within the buffer tube, and are crucial elements for the AR’s cyclic action. The buffer is the contact point for the bolt carrier to move rearward within the tube and the spring resides in the most aft position of the assembly.

Note: Gun Engineer always recommends any part be installed by a qualified and trained gunsmith. Gun Engineer promotes the use of safety practices and gear when working on any firearm.
