From the manufacturer
The RB5004 KynSHOT Marksman Recoil Buffer from KynSHOT reduces felt recoil 20-30%, while largely eliminating muzzle rise. The improvement in weapon accuracy – specifically second- and third shot accuracy – is even more noticeable as shooters report that their time to reacquire a target decreases, and in many cases never leaves their scope sights. In our experience, the more serious the shooter, the greater the improvement is felt. The RB5004 KynSHOT Marksman Recoil Buffer is a proven system that has seen heavy use with civilian competition shooters, law enforcement personnel and the US Armed Forces. Buffer is 2.5” long, and replaces buffers that are 2.5” long. Designed for 7.62mm/.308 AR style rifles with an M4 length buffer tube (which is 7” deep, and ¾” shorter than an Armalite AR-10 collapsible stock tube). This is a common factory stock arrangement on many factory .308 rifles such as DPMS, CMMG and many others. Also works well with other calibers based on the .308 case such as the .338 Federal, .260 Remington and .243 Winchester if they have the M4 buffer tube. If you buy an aftermarket AR-15/M4 collapsible stock tube (receiver extension) for your .308 AR, this is the buffer you will need. The Magpul UBR stock also uses an AR-15 carbine length stock tube and would also require this buffer if used on a .308 rifle. High strength 17-4 Stainless Steel construction throughout the unit, making it virtually impervious to corrosion. Military grade materials and processes used in manufacture. Guaranteed 10 years or 1 Million Rounds.
