    6mm arc barrel

    Posted by David on May 4th 2023

    I honestly didn’t expect the quality to be so good. I bought this for a hunting rifle build with the expectation of it not being very accurate beyond 80 to 100 yards. To keep this review short, it’s an absolute tack driver at 100 yards. It loves 95 to 103 grains. It sub moa . No where did I read that it would be nor did I expect that for the price. I tried lighter bullets and it would be sub moa but I kept having the occasional flyer. I highly recommend this barrel for your next build!
