The buffer spring is a wear item. Over time it can lose tension, which can change how the rifle cycles, so replacing it is a simple way to restore reliable function. The spring works together with the buffer, and the weight of the buffer and the strength of the spring determine how quickly the bolt carrier returns to the firing position.

A carbine-length spring is made for a carbine-length buffer tube, so check your tube before ordering. It is a small part that is easy to install on a new build or as a replacement.

Aero Precision applies manufacturing standards drawn from its aerospace background to every handguard, receiver, and small part it builds, giving shooters components that fit together the way a factory rifle would rather than requiring extra fitting at the bench.
