Who This Is For
This muzzle brake is ideal for AR-15 owners who are currently running their rifle without a suppressor but want the ability to quickly mount a Dead Air Sandman series can in the future — without swapping muzzle devices. It's equally well-suited for competitive shooters, hunters, and tactical enthusiasts who want a high-performance standalone brake that delivers noticeably flatter shooting and reduced felt recoil right out of the box.

Frequently Asked Questions
Can I use this muzzle brake without a Dead Air suppressor?
Absolutely. The Keymount Muzzle Brake functions as a fully capable standalone muzzle device. It effectively reduces felt recoil and muzzle rise on its own, making it a worthy upgrade for any 5.56 NATO AR-15 — whether or not you plan to add a suppressor later. Many shooters run it as a permanent brake with no intention of mounting a can.
Which Dead Air suppressors are compatible with the Keymount Muzzle Brake?
The Keymount Muzzle Brake is designed specifically to interface with the Dead Air Sandman series of suppressors, including the Sandman-L, Sandman-S, and Sandman-K. These suppressors use Dead Air's KeyMount system for quick and secure attachment. If you own or plan to purchase any of these suppressors, this brake is the correct mounting device for your 1/2x28 threaded barrel.
Will this muzzle brake fit my AR-15 barrel?
Yes, provided your barrel has a standard 1/2x28 thread pitch, which is the most common threading on AR-15 barrels chambered in 5.56 NATO or .223 Remington. Before purchasing, verify your barrel's thread pitch — some specialty or non-standard barrels may differ. The Keymount Muzzle Brake is not compatible with .308/7.62 NATO barrels, which typically use 5/8x24 threading.
