Brownells 6.5 Grendel Barrel & Bolt sets

[Larry in SD]

If this has been asked before I apologize as I looked and did not find it.

Been wanting to build a 6.5 Grendel for quite a while now but still can not seem to save up the needed funds (however I am working on it). I looking at Brownells I see they have listed 18" & 24" 6.5 Grendel Barrels that come with a Bolt. The details show a 5R Rifling with 1 in 8" Twist for the 24" Barrel much the same that Midway USA lists for their barrel(s).

What can the experts here tell me about the Brownells 6.5 Grendel Barrels?

Thanks

Larry
