This CMMG .308 Barrel is the perfect solution to your Mk3 build. It is machined from 416 stainless steel with a salt bath Nitride finish inside and out for ultimate accuracy and durability. The Medium taper profile is a great all-around barrel that is rigid without being overly heavy. A rifle length gas system combined with the 16.1” overall length is great for reliable and smooth recoil. This .308 Winchester barrel is machined for precision and is threaded 5/8x24 for compatibility with .30 caliber muzzle devices. If you are looking to build an AR-10 that is accurate without being 20 inches with a heavy profile, this barrel is a step in the right direction.
