Tune Your Overgassed AR-15 with Recoil-Reducing Heavy Buffers
If your rifle is throwing brass forward and recoiling sharply, you’ve likely got too much gas in your recoil system. Most commercially available barrels have an enlarged gas port to ensure the rifle can cycle lower-pressure loads and steel cased ammunition. For an ideal shooting experience, with reduced recoil and wear on your system, a heavy buffer is a perfect upgrade.
A heavy AR-15 buffer adds mass behind your bolt carrier group, slowing the velocity of your entire recoil system. Each buffer contains three weights, separated by rubber spacers. The weights act similarly to a dead blow hammer, reducing the amount of rebound when the bumper meets the rear of the buffer tube.
Which Heavy Buffer Do I Need?
Which buffer weight your gun requires depends how overgassed your rifle is. Typically, we recommend an H2 buffer to solve most issues in terms of recoil reduction and wear. For finer tuning a rifle that doesn’t necessarily have issues, an H1 is probably the right fit. If your gun is actually showing signs of damage from cycling, go for an H3.
