Dead Air DA106 KeyMo Muzzle Brake Black Nitride 4140 HT Alloy Steel M18X1.5 Threads 338 Cal
$75.00
The Dead Air DA106 KeyMo muzzle brake is built for shooters who want a top-tier brake now and the option to run suppressed later. This 338-caliber brake features Dead Air's sealed taper design—a smart engineering choice that lets you swap suppressors without the frustration of carbon lock-up. Whether you're chasing flatter recoil and reduced muzzle concussion on the range, or you're planning to eventually thread on a KeyMo-compatible Sandman Series suppressor, the DA106 does both jobs well.
Built from 4140 HT alloy steel and finished in durable black nitride, this brake weighs just 4.10 ounces and measures 2.82 inches long. The M18x1.5 thread pitch is common on larger-caliber rifles, and the sealed taper design sits forward of the KeyMo locking channels—a detail that matters when you're swapping gear in the field or at the bench. Unlike some other models in Dead Air's lineup, the DA106 doesn't have a pre-drilled pin-and-weld hole, so it's suited for direct-thread or removable mounting applications.
This is a straightforward tool: solid construction, proven design, and the flexibility to become part of a suppressor setup whenever you're ready. If you shoot 338 caliber and want a muzzle brake that won't limit your options down the road, the KeyMo system is worth the consideration.
