Atheris 12.7x42 Barrel & Bolt

Quality seems top-notch

My second barrel and bolt head combo purchase from you, and the quality once again is perfect. The cerakote is flawless and looks great, and the bolt head runs trouble free. Immediate response to any questions also. Thanks and I look for to doing more business with you.

When I decided I was going to do a .50 Beowulf build, finding a quality barrel became top priority. I found a few options, but most were quoting several months for delivery. I contacted Atheris and was quoted 3 weeks, by far the shortest. I went ahead and placed an order and received shipping notification only 3 days later. The barrel itself is absolutely beautiful. The rifling looks great and the workmanship is fantastic. I was also happy to see that the barrel came dimpled and ready for a gas block to be installed. With a <1moa guarantee I am thrilled. I have not completed the build yet, but I have high hopes.

love this barrel and bolt thr barrel looks superb in finish and quality rifling looks super chamber is beautiful i will definetily buy from Atheris again. recieved a phone call from zach in reference to a issue ihad that turned out to be design enhancment he was prompt to resolve the question with very satisfactory results as there wasnot an issue to begin with just a brain fart i had thanks zach and i highly reccommend them just be patient with delivery times as covid and gun demand have paralyzed this industry but these are worth the wait ipromise. i was an machinist tool maker and cnc machinist in a close tolerance bearing factory we made helicopter jet and tank bearings been in thebusiness thanks

I am a toolmaker by trade so I do machine work all day long and I am very picky when it comes to accuracy and I am impressed by what i received.

It's excellent.

Very impressed with the barrel that I ordered. The finish work is amazing and would highly recommend buying from Atheris. Great company with great customer service also, they answered all my questions and got back to me really quick. I would give them a higher star rating if I could.

This barrel is awesome! It took 3 rounds to sight it in and it’s spot on since with less than 1 MOA.

Received as ordered. Excellent customer service during this challenging time of finding AR parts. Always provided an update when asked. Barrel looks of great quality. Just finished my pistol build. Can't wait to try it out once I can get my hands on ammo that is currently on back order. LOL. Thanks again!!!

Ordered this for a build and am nothing but happy. Thought I had a gas problem and installed a tubbs flat buffer spring and it fixed it. Will definitely buy from them again.

Nice barrel....just what I ordered!!
