Experience superior recoil management and seamless suppressor integration with the Dead Air KeyMo Muzzle Brake 5/8-24 .30 CAL. Designed for demanding shooters, this precision-engineered device combines aggressive recoil reduction with Dead Air's proven KeyMo quick-detach mounting system, delivering a flatter shooting experience whether used standalone or paired with compatible suppressors. Key Features Recoil-Reducing Design: Multi-port configuration vents gases to minimize muzzle rise and felt recoil, enabling faster follow-up shots and improved control on .30 caliber platforms. KeyMo QD Mounting: Serves as the interface for Dead Air Sandman series suppressors and other KeyMo-equipped models, ensuring repeatable lockup and consistent point of impact. Sealed Taper Technology: Precision-machined taper positioned ahead of locking channels prevents carbon buildup, allowing easy suppressor removal even after extended firing sessions. Durable Construction: Machined from 4140 heat-treated alloy steel with a black nitride finish for exceptional strength, corrosion resistance, and longevity under hard use. Pin-and-Weld Ready: Pre-drilled 6 o'clock hole facilitates permanent installation on shorter barrels while maintaining legal compliance. Specifications Thread Pattern: 5/8x24 Caliber Compatibility: .30 (7.62/.308) Overall Length: 2.82 inches Weight: 3.9 oz Material: 4140 HT Alloy Steel Finish: Black Nitride Includes: Shim kit for proper timing Why Choose This Product Shooters often struggle with excessive recoil and the hassle of suppressor attachment. The KeyMo Muzzle Brake addresses both pain points by providing effective brake performance on its own while serving as a reliable gateway to suppressed shooting.
