These work very well – Fired a few hundred rounds with a super safety without any problems. Great customer service too. Originally sent me the wrong barrels, but they immediately sent me the correct ones and a return shipping label upon contacting them. Stuff happens, but these guys handled it perfectly.
Amazing fit and finish – These barrel feel like quality pieces the moment you hold them. The finish was perfect, the threads allow my flash hider to screw on like butter. The bore and rifling look amazing. The fit of the barrel to the upper was super tight, I put my upper in boiling water for about 30 seconds and the barrel in the freezer for 30 minutes and they slid right together. This fit is what I would expect from a barrel that costs way more, I am amazed and couldn’t be happier with the fit. I am confident the accuracy is going to be exactly what I expect. The feed cone fed flat nose rounds perfectly with no polishing and no work. I’m looking forward to years of use of this barrel.
sound of freedom – This was a great set up. I loved being able to customize the set up. Only issue I had was my own fault as a newb to building these. I used a heavy barrel in a slim hand guard. It makes adding attachments tough with clearances. Hoping someday to also get an AR10 from here.
