Buffer Technologies recoil buffers are used to reduce parts wear and recoil of your firearms. These polymer recoil buffers prevent the metal-on-metal impact of a bolt or slide from impacting the frame while firing. They are made from Estane 58130, which is not affected by common firearm cleaners, making them last for hundreds of rounds.

The AK/Valmet Recoil Buffer fits on the recoil spring guide rod of any Kalashnikov style weapon. This includes AKs, Valments, Galils, Vepr, and MAK 90s. Installation takes less than a minute and be done without any special tools.

Each time you fire your rifle the gas system propels the bolt carrier to the rear very violently, which generates a shock wave that is absorbed by the metal receiver. After a period of time, this repeated pounding causes the action itself to lose its structural integrity. The most notable side effect of this is the difficulty one has in controlling the weapon during rapid fire. 

By installing a Recoil Buffer you totally eliminate the metal to metal impact of the bolt carrier to the receiver and most of the action noise. 

Those who install Recoil Buffers into their AK's will not only be protecting their investment by prolonging its service life, but they will also find that the recoil is reduced and muzzle stability is increased.
