AR-15 5.4oz H3 Buffer

AR-15 5.4oz H3 Buffer

The AR-15 5.4oz H3 Buffer is a heavy carbine buffer designed for compatible AR-15 recoil systems using a standard carbine-length receiver extension. At 5.4 ounces, it provides additional reciprocating mass compared with lighter carbine buffers and can be used when a rifle configuration benefits from an H3-equivalent buffer weight.

The steel carbine buffer body contains three sliding brass weights and measures 3.25 inches long. Heavier buffer configurations can slow rearward bolt carrier movement and change the cycling characteristics of the rifle, making buffer weight an important tuning consideration for suppressed, short-barreled, or otherwise heavily gassed configurations.

Buffer selection should be matched to the complete firearm setup, including barrel length, gas system, ammunition, bolt carrier group, and suppressor use. Function should be tested with the ammunition and configuration that will actually be used.
