Brownells AR-15 H1 Carbine Buffer Features The Brownells AR-15 H1 Carbine Buffer is weighted at 3.8 ounces to provide the lighter end of the standard carbine buffer range which can help tune cycling speed on certain AR-15 builds. Buffer weight directly affects how the bolt carrier group cycles under recoil and selecting the correct weight for your gas system and barrel length is critical to smooth reliable function. This buffer is built to precise tolerances so that it interfaces correctly with mil-spec buffer tubes and springs. Getting the buffer weight right reduces felt recoil and bolt bounce which keeps the rifle running consistently through a range session or in the field. Finished in gray and constructed for AR-15 platform rifles this buffer fits standard mil-spec buffer tubes for a simple drop-in installation. It is sold individually making it an efficient way to keep a spare on hand or to complete a parts build without unnecessary extras. Builders assembling a rifle from individual components can use it to finish out the buffer system alongside a compatible spring and buffer tube. The Brownells AR-15 H1 Carbine Buffer is a dependable option for any AR-15 owner looking to fine tune or restore proper function to their rifle.
