New KeyMo-Compatible Muzzle Brake Available Only at Primary Arms

Now available at Primary Arms, Expo Arms and Forward Controls Design have partnered to create an exciting new muzzle brake, optimized for 13.9” AR15 carbines.

Dedicated to 100% US-based manufacturing, Expo Arms puts quality and value above all else. Expo Arms products are created in partnership with the industry's top manufacturers, upheld to exceptional standards, and feature a comprehensive lifetime warranty backed by Primary Arms' legendary Customer Service. From barrels to handguards, receivers, triggers, and more, Expo Arms pursues excellence in all their AR15 components, and this new muzzle brake is no exception.

The Expo Arms KeyMo 1/2x28mm Muzzle Brake [SKU: XP-1215KM] is a single-chamber muzzle brake with exceptional recoil mitigation and built-in compatibility with the KeyMo suppressor mounting system. When paired with a Dead Air Sandman suppressor, this brake acts as a sacrificial baffle, improving longevity and performance of the suppressor. Its 4140 steel construction and black Nitride finish further enhance durability, and with an overall length of 2.7 inches, the Expo Arms KeyMo Muzzle Brake will reach 16-inch OAL when paired with a 13.9” barrel. Enthusiasts can expect the same level of quality and craftsmanship as all other premium Forward Controls Design products, making this muzzle brake an impressive addition to the budget-friendly Expo Arms product line.

“Expo Arms delivers on top-quality components and parts for any budget, and this muzzle brake upholds that strict standard,” says Matt Okun, Primary Arms’ Senior Merchandising Manager. “With the growing popularity of 13.9” barrels among builders, this muzzle device will give you optimal control with just enough length for pin-and-weld.”

Priced at $109.99, the Expo Arms KeyMo 1/2x28mm Muzzle Brake is now available at Primary Arms. To learn more about this muzzle brake, or to order one for yourself, click here.
