308forlife

Thank you so much 392heminut, That is what I was thinking it would be...seems as though the industry "standard" for the most part is .730" muzzle for barrels with a .750" gas block and .920" for .936" gas blocks. I suppose this is to make it easier to slide that gas block all the way on without getting a bunch of scratches on the barrel. Appreciate the help.

I quickly am realizing that poverty comment ha. There are worse things I could spend money on.

Anyone who has a LR-308B with the 18" bull barrel I really need to know the diameter of the barrel at the muzzle. I have a LR-308B upper on the way and have a local machinist working on a muzzle brake for me. Since i dont have the barrel yet in oreder to proceed I really need to know the diameter of the barrel at the muzzle. The spec on it says .936 at the gas block but i want to double check what it is at the muzzle since most barrels have a slight taper. Anyone who could grab some calipers and measure their LR-308B would be greatly appreciated. Thanks
