i am now scared to purchase another barrel from black hole weaponry. not to mention i ordered a 24 in heavy barrel unthreaded. after about a 8week wait i got a 24 inch heavy barrel that was threaded. i called them about it. i told them i didn't order a threaded barrel, but i was keepig it since i had already waited 8 weeks for it. they sent me a free muzzle brake for it.

that rifle has a new barrel on it now. i had to custom order a 26 inch barrel for it. it is now a 1/2 m.o.a. shooter that has over 2000 rounds down the pipe now. i sold it to a guy at work earlier this summer. he loves it.


That's not good. I just purchased a BHW barrel chambered in 6.5 Grendel. I've only had it out once so far and it shot great with factory Hornady 123 amax. Hope it doesn't wear out like the one you had. Fingers crossed.
