Buffer
Great customer service I will definitely order again from AR15 discounts
USCompensates for Overgassing
These buffers are equivalent to H2 buffers and work great on my builds with carbine length gas systems.
USDon't let the price fool you.
Perfect weight for carbine length gas system when running FRT or SS.
USGreat price on a slightly heavy H2 buffer
I have installed it, but haven’t gotten to the range with it yet. It’s .10 oz heavier than the H2 that was in the gun already so I don’t anticipate any issues. Seemed solidly built and obviously it has buffers inside which keep the weights from moving around.
United StatesGo big for .30 cal
Pair this with an adjustable gas block on a .30 cal AR15 platform, and notice how much softer everything is. Amazing upgrade.
