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.
