Just got this barrel to upgrade from a stock, medium contour, chrome lined barrel. The difference was readily apparent. Quality machining, less weight, and more accurate. I was able to pull off 1” groups at 50 yds with 62 grain bulk ammo and an Aimpoint. Expect better when I try match ammo and a magnified optic. Great part!
