XK9 9mm Hydraulic Buffer

SKU # : XK9Buffer





Categories: , SKU: XK9Buffer


The XK9 Hydraulic Buffer is a specially engineered Heavy Damped KynSHOT Buffer for the 9MM PCC application. Designed in cooperation with Kynshot to work for 9MM applications with barrels 8” or greater, either suppressed or unsuppressed and with any type of ammo. The hydraulic fluid and seals are made to meet mil- spec requirements and have an ambient temperature operating range of -30F to +150F. The KynSHOT uses patented hydraulic shock absorption technology to dampen the impact of the bolt at the rear of its travel and to dampen the forward impact of the buffer’s weight as it chambers the next round. Its weight and length have been optimized for the 9MM application so that it runs reliably, softens recoil, smooths out the action, and stops just behind the bolt catch.
