Ratings & Reviews
I have had my AR10 for over a year and have had the following issues. Feed Ramps eating up brass littering my upper with large brass shavings. Gun will not fully chamber a round unless you apply excessive force to the BCG. Gun have issues ejecting spent rounds. I have changed buffer spring weights, buffers, BCG, Magazines, Cleaning, Ammo, and Lubes with no success. I have suspected the barrel but now after seeing the other reviews I am more confident the barrel may be the cause. I am going to replace this barrel with a quality product.
Catastrophic Failure; Absolute Garbage; Spend more as your life depends on it

Purchased this barrel for a build, and couldn't achieve lock up. Bolt had to be forced closed to achieve full lock up. The forward assist wasn't strong enough to push the bolt closed. Primary Arms assisted quite well in getting barrel sent back to Anderson but once Anderson took over, there customer service and communication was atrocious; you get better service at Walmart! This barrel should have never left Anderson with the headspace issue it had. Could have caused a serious accident with deadly results.
If you use a dual ejector bolt it will chew-up brass and cause it to jam a lot. Just a FYI. Too much side loading on the brass going in and coming out shaves a lot of brass. That was my experience. Switched to a single ejector bolt and the problem went away and it worked fine.
Works like a Swiss watch. Very accurate. Great bargain. Needs to be cleaned before use.
You get what you pay for
The feed ramps/lugs were not de-burred and very rough. Chews up brass like nothing I've seen. But for the price i'll live with it.

This barrel is a project or at least mine was the chamber was extremely rough it couldn't eject the brass, I had use a soft .357 brush and polish to smooth it out but now it works great.
