Atheris Rifle Co Barrel Chatter Marks on Rifling

[kmk1012]

I just received a new barrel and headspaced bolt from them and was a little disappointed in the quality. It's a 12.7x42 (50 Beowulf) that was bought to replace the junk bolt from Bear Creek. Do you think these are bad enough to effect accuracy? It's not a long range gun but don't want to mount it as it won't be returnable afterwards. Here's a pic of the rifling.

Do you know if they are the ones making the barrel or just finishing them. It might be something out of their control. They might just be bulk ordering blanks or even completed barrels from questionable sources.

 

[kmk1012]

I don't know much about them other than they were recommended as a good barrel to me. I may just mount it and see, I really don't know if it will be detrimental to accuracy though. I can see it leading more rapidly though.

You could always fire lap that barrel in, if you reload, its super easy to do!

I checked out their site.

Nothing about their barrels is mentioned.

They have a similar feeling to all other small AR15 companies. I highly doubt they are making their barrels, maybe machining blanks. Hard to say. Likely getting them from someone for cheap. I'd be curious if they have any markings on them?

They did have a 1moa guarantee on the barrel page, I'm curious if that coincides with the warranty?

I'll look into that, sounds fairly easy.

Hey bud dont fire lap it. Just call the owner zach that his cell phone on the website. He will take care of you he is awesome to deal with. Him or the lady are good people. I am pretty sure his blanks are now made by liberty, on his older ones were t-box but he couldn't tell people because his price was so low and other dealers started grumbling about his prices he is a good dude give him a chance before you fire lap it.

Tried firelapping for the first time on a Rem 700 .308 and what a difference it made, the bore is mirror polished now.

Did you have a problem with the BCA bolt?

I'm curious about how to fire lap.

Fire lapping is done with various abrasive projectiles you can get in kits.
I use the Tubbs 2000 product, and I can vouch that it works quite well!

Thx
I'll have to contact them for the .50, not seeing it immediately. That's cool though, thx again

Yes, it seemed soft and was peening or mushrooming over at the extractor.

He also runs a group on Facebook. .50 Beowulf he's on it quite a bit answering questions, I'd give that a try if you can't reach him.
