KynSHOT
KynSHOT makes hydraulic recoil buffers that replace a standard buffer to smooth out an AR-platform rifle's cyclic rate and reduce felt recoil — a popular upgrade for suppressed rifles, over-gassed builds, and shotguns that kick harder than they need to. Impact Guns carries their buffer lineup across AR-15, AR-9, .308, and shotgun platforms.

How a Hydraulic Recoil Buffer Works
A standard AR buffer is a solid weighted mass; KynSHOT's hydraulic buffers use an internal damping mechanism that absorbs bolt carrier impact more progressively, smoothing out the sharp rearward slap that a standard buffer transmits to the shooter's shoulder. This is especially noticeable on suppressed or over-gassed rifles, where excess gas makes the bolt carrier cycle harder than it needs to.
Matching a Buffer to Your Stock Type
KynSHOT sells separate buffers for collapsible (carbine), fixed, and short-stroke stock configurations, plus caliber-specific versions for .308 and 9mm AR platforms — the buffer has to match both your stock tube type and your rifle's caliber/gas system, so confirm both before ordering.
Shotgun Recoil Buffers
KynSHOT extends the same hydraulic damping concept to shotguns with a collapsible stock adapter, available in adjustable and non-adjustable versions — a meaningful recoil reduction upgrade for anyone shooting a tactical shotgun with a mil-spec-pattern stock.
Frequently Asked Questions
Will a KynSHOT buffer affect my rifle's reliability?
When matched correctly to your stock tube and gas system, a KynSHOT buffer maintains normal cycling while reducing felt recoil. Using the wrong buffer for your configuration can affect reliability, so confirm compatibility with your exact rifle before ordering.
Do I need a KynSHOT buffer if I already run a suppressor?
Not required, but many suppressed-rifle shooters add one specifically because suppressors increase back-pressure and gas volume, making the bolt carrier cycle harder — a hydraulic buffer offsets some of that added recoil.
