Ultradyne USA Apollo S Muzzle Brake 6.5 Creedmoor 5/8x24 – AR-10 & Bolt-Action Rifles

The Ultradyne USA Apollo S muzzle brake is engineered to significantly reduce felt recoil and muzzle rise in 6.5 Creedmoor rifles, allowing faster follow-up shots and improved accuracy during extended shooting sessions. Its compact single-chamber design redirects combustion gases to counteract recoil forces while maintaining a shorter overall length compared to multi-baffle brakes, making it well-suited for both precision rifle competitions and hunting applications where maneuverability matters.

This brake features 5/8x24 TPI threading, the standard for most 6.5 Creedmoor barrels on AR-10 pattern rifles and many bolt-action platforms. Machined from heat-treated steel with a durable black nitride finish, it installs with standard armorer tools and includes a crush washer for proper timing. The Apollo S uses strategically angled ports that direct gas rearward and laterally to minimize concussion directed at the shooter while maximizing recoil reduction.
