    Hard to believe the price on this barrel that does nothing but shoot tight groups. A friend and myself each ordered one, taking what felt like a gamble being such a cheap price. Both built on Aero M4E1 uppers, his being a DI gun and mine a modified Adams Arms piston system. Sub MOA with 77gr Sierra tipped match kings (0.62-0.90“ groups at 110 yards). I load my rounds and friend shoots IMI. Also found an excellent load with 69 Sierras that holds steady at 0.85-1.21“. Very happy with this medium contour barrel! Have been comparing with the 18“ stainless rifle length fluted barrel(see review) and will be ordering the dimpled version to continue the tradition of KAK barrels on my accuracy builds.
