Product Description

The KynSHOT RB5005 Recoil Buffer is designed for AR-10 carbines with a collapsible stock that use the standard AR-10 length tubes that are 7.75″ deep on the inside. The RB5005 reduces felt recoil 20-30%, while largely eliminating muzzle flip. 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. This buffer has patented damping technology to absorb the shock of impact from the bolt carrier’s rearward motion and to prevent bolt bounce as a new cartridge is chambered. (ECCN Controlled)

The best way to confirm is to measure the length of the buffer that came with the rifle from the factory.
