You just love your new AR-10 carbine, so why do you want to wear it out too soon? That’s what you're doing when you leave the factory buffer in it. You need to change to a Kaw Valley AR10 buffer so your new baby will be around longer for you to enjoy.

Over-Gassed Means Overused

The action on most AR-10s is severely over-gassed and comes with a factory buffer that is just too light to get the job done. You need a KVP .308 heavy buffer so your AR-10 carbine can take a breather between rounds, even only for a millisecond. A heavier KVP .308 buffer will give your weapon that millisecond to rest. Therefore, all of the internal parts will take less abuse and live to fight another day. A heavier KVP .308 carbine buffer slows down the dwell time of the action ever so slightly. You get to enjoy less felt recoil and your weapon gets to enjoy a little break.

High Performance, High Quality Yet Affordable

Kaw Valley Precision machines their .308 carbine buffer body from stainless steel right here in America. KVP turns out every AR10 heavy buffer to exacting standards and you should demand no less. You watch what you put into your body and you should watch which .308 buffer you feed your AR-10. When you think top of the line you think stainless steel, tungsten carbide, you think Kaw Valley Precision. That’s what they think when they choose materials for your new .308 heavy buffer. However, at KVP they also think efficiency, therefore, they keep costs to a minimum. That means you can enjoy your new AR10 buffer for much less than you think.

    Replaced the old 3.2 oz buffer with this one, Recoil is less and the brass is not getting marks on them from the ejector .

    A must have on a short barrel 308 build. Can't say enough about Wing tactical speed of shipping and cost. A great company to deal with.

    Excellent product at a far more reasonable cost when compared to other brands. This buffer solved my short stroke / double feed / stove pipe problems. My LR-308 runs flawlessly now. Thank you!
