I just got one from the group buy and it's a work of art.
Here's a link to there website:

Grendel info is at the bottom of the page.
Contour specifications for 6.5 Grendel barrels:
At the time of our 6.5 Grendel barrel introduction (January 2014) we are making these available in four 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 two mid-length gas system contours; our 17" long contour 304 and 19" long contour 318. To see drawings of these contours click on the designation: AR740, AR24, 304, 319. 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).
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. Bolts are not included. We suggest contacting Maxim Firearms for an MF bolt at 928-486-2296.
Barrel extensions are an M4 type.
