The Apollo S muzzle brake from Ultradyne provides a scientific approach to reducing recoil and improving muzzle control. After studying thousands of recoil events, the engineers at Ultradyne have come up with a brake design that uses less aggressive gas venting that virtually eliminates muzzle rise. The brake is rated for over a dozen calibers, including the 223 Rem and 5.56 NATO.
The Ultradyne Apollo S muzzle brake five-port design has been engineered to strike the perfect balance between less aggressive gas venting, recoil reduction, and decreased muzzle rise. This results in the brake evening out recoil and providing an ultra-smooth shooting experience like no other muzzle brake on the market.
The Ultradyne Apollo S muzzle brake is CNC machined from 416 stainless steel and given an ultra-rugged salt-bath nitride finish. Weighing in at just 5.2 ounces and measuring only 2.94 inches long with an outside diameter of just 0.975 inches, the brake won't weigh down your platform or get in your way. Indexing slots are designed to be compatible with the Dynamount front sight for either a 45-degree offset or standard upright alignment.
The Apollo S muzzle brake installs easily on barrels at least 14 inches long and has a 1/2"-28 thread pitch using a standard 13/16 inch wrench. No special gunsmithing knowledge is required, and a timing nut is included.
