Daniel Defense Carbine Buffer Spring AR-15

The Daniel Defense Carbine Buffer Spring AR-15 is a carbine-length buffer spring for AR-15 rifles with an M4-type carbine buffer tube. The buffer spring is a wear part of the operating system, and its condition affects bolt carrier group movement and the reliability of the rifle.

A spring that has lost length or tension can cause feeding, extraction and lockup problems. A spare spring is useful especially for rifles that see a lot of training or competition use, and the spring is also suitable for a new build.
