True Match-Grade Heavy Contour Competition Barrel
This stainless steel match barrel from Krieger features a minimum-spec .223 chamber and hand-lapped, single-point cut rifling with a 1-7.7" twist rate that’s ideal for 69-80 grain match bullets. Heavy “H-Bar”-style contour and 20" length make this barrel ideal for service rifle competition. Available in Pre- or Post- Ban configuration (with or without ½"-28 tpi muzzle threads). All critical dimensions have been ground between centers to be concentric to the bore, and the gas port has been precisely located in one of the grooves of the rifling. Krieger recommends the use of a standard Parkerized mil-spec bolt with this barrel; due to the minimum chamber, it may not headspace properly with chrome-plated or nickel-boron coated bolts. .750" O.D. at gas port. .093" dia. gas port. 3.5 lb. wt.
