6mm ARC

[A5BLASTER]

I just received my Shaw 6mm ARC barrel yesterday and this thing has a short throat. Both Hornady 108s and 105s are sticking horribly and the bolt won't close. This is with a .136 Grendel bolt. I tested with the ejector and extractor removed. This bolt, although never fired, has been used to test headspace on Go/No Go gauges in a Grendel barrel, so I know it's not an issue with the bolt.

Shaw asked me what bolt I was using and I told them .136. Their reply was "The bolt face is not deep enough, the ARC uses a Grendel 2 headspace off of a .140 depth bolt face."

I asked them where they got that incorrect information (I assume the person is rounding), and I'm waiting for their reply. But that doesn't give me much confidence in them. Never mind that even if the bolt depth was .140, the lugs still wouldn't engage in the barrel extension properly (see pic #2).

Also, the packaging that this barrel came in was destroyed when I received it. I really thought the barrel was going to be damaged but it appeared to be fine once I got it out. Boy am I disappointed; I had all of my other parts ready to assemble so I could shoot this weekend.

Soon as he would have told me that mess. I would have told them it's in the mail back to you and I want a refund and will contact my back and lawyer to fight to get my money back.

To the best of my knowledge there is not a single bolt manufacture that makes any bolt for any ar15 cartridge with a .140 bolt face depth.

I'm with vascar they dropped the ball and dont want to admit to their mistake and also believe like vascar the reamer most likely came from ptg.
