With fits for many of today's popular calibers, ranging from .223 all the way up to 9mm, the ODIN Works ATLAS Compensator provides options for shooters looking to reduce the felt recoil experienced in their AR-style platform, whether it's an AR-15, an AR 308 or a pistol-caliber carbine. Each ODIN Works ATLAS Compensator is machined from stainless steel and treated with a black-nitride finish to prevent wear and corrosion. The compensator includes a timing sleeve machined from titanium, which prevents users from having to use shims or crush washers to properly orient their muzzle device. The overall length of the compensator ranges from 2.5 inches for 9mm compensators to 3.06 inches for .30-caliber compensators. The weight also ranges from 3.9 ounces to 4.4 ounces, depending on caliber.
