Product description
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.

Alexander arms 50 Beowulf 16 inch recommended spring and buffer? I just bought an h3 and stronger spring
Michael Souther · Jun 2, 2026AT3 Support Team — For a 16-inch .50 Beowulf, Alexander Arms actually recommends a standard carbine buffer and standard spring, so your H3 buffer and stronger spring will likely cause short-stroking unless your rifle is heavily over-gassed.

Best weight for the Ruger SFAR in .308?
Spencer Allen · Dec 11, 2024AT3 Support Team — The H2 buffer is often recommended for .308 setups, especially with a 16-inch barrel. It provides a good balance between managing recoil and ensuring reliable cycling.
AT3 Support Team — The recommended buffer weight is typically around H3, which weighs approximately 5.4 to 5.6 ounces.
