At the time of our 6.5 Grendel barrel introduction (January 2014) we are making these available in three contours. These are the AR740 and AR 24 contours shown above as standards for the 204’s and .223’s and in addition we are also stocking one mid-length gas system contours; our 19″ long 319 contour. To see drawings of these contours click on the designation: AR740,AR24 ,319. The 740, 319, and AR 24 profiles are also available in a fluted version. All 6.5 Grendel barrels are threaded at the muzzle with a 5/8″-24 thread – (although the linked drawings above may show 1/2-28). Weight is 2.16 pounds.

The 6.5 Grendel barrels are headspaced using a Maxim Firearms bolt. Headspace may not be correct with our barrel using an Alexander Arms or LBC bolt.

We also have for sale a 6.5 Grendel bolt made by Maxim Firearms. This bolt is a perfect match for our 6.5 Grendel barrels.
