The K-SPEC Buffer was developed with specific goals in mind- Reducing felt recoil and providing faster follow up shots. With modern technology being applied to firearms, you’re likely aware of the recoil management solutions that have been applied to many popular pistol operating systems. Many recoil rods in pistols went from a single piece recoil rod assembly to a dual recoil rod spring assembly with compression guide rod.


With the modernization of firearms, we found out a way to apply this technology to the AR15, AR10, and pistol caliber ARs.


The K-SPEC Buffer features an innovative recoil reduction system that absorbs and disperses felt recoil. Minimizing muzzle flip and kickback allowing you to fire faster and more accurately by being able to stay on target more effectively.


The K-SPEC Buffer features a two-piece reciprocating buffer body and a custom captured compression spring mechanism internally, which works in conjunction with our flatwire buffer spring. The majority of the felt recoil is transferred into the buffer spring, and then dispersed into the K-SPEC buffer internals which absorb recoil and distributes recoil more evenly and linearly instead of abruptly as you experience with traditional buffer systems.
