Barrel, 22" M14/M1A, Heavy Contour, 1x12, Chrome Moly, Krieger

Krieger Barrels, Inc. manufactures precision single-point cut-rifled barrels, which is the oldest and slowest method of rifling a barrel. The cutter removes approximately .001" at each pass, thus taking several hundred passes to rifle a barrel. This produces near perfect concentricity between groove & bore, a very uniform twist rate, and induces no stress into the steel which later has to be relieved. The barrels are hand lapped after reaming and then again after rifling to finishes under 16 micro-inch in the direction of bullet travel.
