Works great - Kaw Valley Precision AR-10 6 Position CAR Stock Completion Kit

I used this in a .224 Valkyrie build, with a Magpul PRS Gen 3. I am using the 4.3oz buffer (red). Runs smoothly with no FTF or short stroking. Recoil is minimal, so I'm calling it a win. One thing I really like is the compatibility of this kit. Buffer weight swaps are easily made to adjust as needed.
