Krinkov style muzzle brakes are designed to direct concussion forward and away from the shooter while also providing some muzzle rise mitigation. However, many of them also turn your carbine into a nose-heavy fence post due to their weight.
The new Helios Muzzle Device from V Seven Weapons is constructed from titanium so it weighs considerably less than what similar steel devices weigh at just 2.5 ounces. It adds 2.2 inches to the over all length of the barrel and has a 1.25″ outer diameter so it can fit under most extended handguards.
The Helios is available in black or silver finishes and 1/2×28 or 5/8×24 thread pitches. The 5/8×24 version will accommodate projectiles up to .338″ in diameter.
