This 6oz stainless steel buffer features a “dead blow” design that helps prevent bolt bounce that can often occur in fully-automatic firearms. Contained inside the buffer are separate “shaker weights” that slide as the bolt carrier cycles, helping to dampen bolt bounce as the bolt closes. Machined from solid stainless steel this buffer weighs 6oz and features a high polish finish and matching polished carbine buffer spring. Extended length buffer does not require the use of a buffer spacer.

Works with both semi-automatic and fully automatic firearms.

  1. Michael R. (verified owner)

    I did receive the part however I’m waiting for the other parts so as to complete my conversion. M16 lower with 9mm upper and this buffer.

  2. EW (verified owner)

    Beautiful part. Really nice finish. More importantly, the dead blow and extended length really seemed to have smoothed out the action. THIS SHOULD BE STANDARD ON THE UDP-9.

  3. Jonathan (verified owner)

    Works perfectly. No problems. Smooth in cycle and function. Looks nicely finished, too.

  4. Matthew W. (verified owner)

    Really helped with cycling, super nice and smooth finish. I highly recommend this product. I’ve had my fair share of “AR-9’s” but Angstadt is by far the best and their products are top shelf, you can’t go wrong!!!!
