Kaw Valley Precision AR-10 Tungsten Buffer Features The Kaw Valley Precision Tungsten Buffer uses heavy tungsten internals inside a 2.5 stainless steel body to add reciprocating mass to an AR-10 carbine length buffer system. That added mass slows the recoil action of the rifle which reduces the sharp snappy recoil impulse that heavier calibers like .308 Winchester can produce in a carbine platform. Weighing between 5.6 and 5.8 ounces depending on natural tungsten density variation the buffer is heavier than a standard carbine buffer which helps the bolt carrier group cycle with greater consistency. This added weight also reduces wear on critical internal components by moderating the speed and force of the reciprocating parts. Built from a stainless steel body the buffer resists corrosion and holds up to repeated cycling far better than a standard mild steel unit. It is designed only for carbine length stocks and pistol kits so builders should confirm their stock configuration before installing. Reducing felt recoil not only improves shooter comfort over long range sessions but also helps keep the sights on target for faster follow up shots. For AR-10 owners seeking a simple effective upgrade to smooth out recoil and extend the service life of internal components the Kaw Valley Precision Tungsten Buffer is available for sale at GrabAGun.
