It is designed to replace the factory 82.5mm / 3.25" buffers.
It is made of durable titanium, aluminum components to reduce weight, and springs that are characterized by long life.
Absorbs recoil much better than normal buffers, keeping the rifle stable so you can fire more shots in less time.
Comes with 3 springs of different weights to choose the right one for your bolt carrier and magazines (Heavier bolt carriers and magazines with heavier springs need a buffer spring of a higher weight)
