KynSHOT RB5004 “Shorty”

The KynSHOT RB5004 Recoil Buffer is a hydraulic buffer system designed and optimized to fit any AR-10 using a Mil-Spec style carbine buffer tube (internal depth 7").
The RB5004 can also be used with the PDW style buffer tubes that use a 2.5” standard buffer, and the buffer is universal with most calibers.
The RB5004 can be paired with any style AR-10 buffer spring and is a simple drop-in replacement for all buffer systems on the market.

Our buffers patented technology absorbs the recoil impulse from the bolt carrier’s rearward motion, preventing bolt bounce as a new round is chambered.
The RB5004 reduces felt recoil by 30%, improving the shooters overall accuracy and eliminating muzzle flip.
Our test data shows that the time to reacquire a target decreases, and in most cases the shooter will not have to leave their scope after taking their shot.

Designed for 7.62mm/.308 cal. 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. The best reference is that it replaces factory buffers that are 2.5" in length.
Rated for Full Auto Firearms

Compatible 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.
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.
Compatible with all othercalibers that are not related to the AR-10 platfrom, using a buffer that is 2.5" long
