Odin works 18" 6mm ARC XL rifle DMR profile SS Barrel W/ free tunable GB/ B-6MM-18-ARC -2R-TG
Great barrel. No issues with GB. Started with GB almost wide open. Made adjustments until brass was ejecting at almost a 90-degree angle, and everything was cycling properly. Used Hornady BLACK 6MM ARC 105 gr. BTHP to start with.
So far I’m happy
I read reviews of people having cycling issues with their rifle due to the XL gas system length. I did not have this issue. I have the 6 ARC 18 inch Odin works barrel, tuneable gas block, Odin work BCG, carbine buffer spring and H1 buffer. This is the recommended parts from Odin Works. My rifle functions perfectly, I even had to reduced the gas. As far as performance of the barrel so far so good. I have 20 rounds total down the barrel and the it shot a 3 shot group that’s was .6 MOA and one that was .7 MOA. It also shot a 5 shot group that was .9 MOA. This was with Hornady Precision Hunter. I only had a thread protector, no muzzle device. When I removed the thread protector, no muzzle device, the groups went over 2 inches.


Stainless sculpture
Havent really used it yet, but for the price in 6mm arc how could I ignore it? Besides it is so attactive with its genius packaging, I decided it should be displayed as a coffee table center piece. Until wife said not! Anyhow, I like it alot so far, and expect a legendary rifle.
