Kaw Valley Precision Steel Carbine Buffer Features The Kaw Valley Precision Steel Carbine Buffer uses three internal steel weights housed inside a stainless steel buffer body to add controlled mass to the AR platform s recoil system. This additional weight increases weapon reliability by helping the bolt carrier group cycle more consistently across a range of ammunition loads. It also negates bolt bounce a condition where the bolt carrier rebounds forward before fully locking which can otherwise lead to feeding issues or added wear. Stainless steel construction gives the buffer body corrosion resistance and long term durability under repeated cycling. At 4.3 ounces this buffer sits on the heavier end of the carbine buffer weight range which helps reduce felt recoil and smooth out the rifle s cycle compared to a standard carbine buffer. Reducing bolt bounce and cycling harshness also reduces wear on critical internal components such as the buffer retainer action spring and receiver extension over time. The weighted steel internals make this buffer a straightforward drop in upgrade for AR owners running carbine length receiver extensions. The Kaw Valley Precision Steel Carbine Buffer is available for sale at GrabAGun for shooters seeking improved reliability and reduced felt recoil from their AR platform rifle.
