Our High Pressure kit consists of the Kynshot 5004HP hydrualic buffer and Springco heavy(Orange) spring.  This is a carbine buffer and spring for the LR308 (AR10) large frame rifle.

We designed this High pressure hydraulic buffer with the folks at Kynshot and we are the only one who sells it.

The hydrualic buffer helps keep the bolt carrier locked up longer and prevent damage to your brass and lessens pressure.  It also has a significant reduction in felt recoil.

Recommended for Suppressed rifles.
