XTS H2 Heavy AR-15 Buffer

The XTS heavy buffer is an H2 weight AR-15 buffer that comes in at about 4.5 to 4.7 ounces and fits mil spec AR-15 buffer tubes. It is machined from steel.

Adding weight to the buffer slows the bolt carrier as it cycles. That can soften felt recoil, cut down on bolt bounce and smooth out a rifle that runs hard, such as one that is overgassed or wearing a suppressor. It is a quick swap: pull the old buffer and spring out of the tube and drop this one in its place.
