High Polish Stainless Steel Buffer Kit For Semi-Automatic 9mm AR-15 Carbines

The Angstadt Arms AR-15 Stainless Steel 9mm Buffer Kit is designed with full auto use capability but works flawlessly with standard semi-automatic 9mm AR-15 carbines. It features a “dead blow” design that helps prevent bolt bounce that can often occur in fully-automatic firearms.

The buffer weighs 6.3 ounces and is machined from solid stainless steel with a high polish finish that matches the polished carbine buffer spring. The extended length buffer does not require the use of a buffer spacer and it works with both semi-automatic and fully automatic firearms.

Reduced Bolt Bounce

The Angstadt Arms AR-15 Stainless Steel 9mm Buffer Kit utilizes reciprocating weights that help to soften the recoil as well as reduce the amount of bolt bounce as it is closing. Contained inside the buffer are separate “shaker weights” that slide as the bolt carrier cycles, helping to dampen bolt bounce as the bolt closes.

Included with this 9mm Buffer is a polished carbine length recoil spring that results in a smooth feeling action while it is cycling in the receiver extension.
