ZAVIAR Firearms NEW Match Grade 5R Barrel. Great for competitive shooting and target shooting. We are proud to present our "Competition Series" line that is going to give you far greater accuracy than an average barrel.
-Bolt: Nickel boron bolt matched to the barrel chamber for perfect head spacing. Serialized to the specific barrel. (Barrel and bolt serial numbers match)
-Barrel Material: 4150 CrMoV
-Gun drilled and reamed for optimum surface finish, and size prior to rifling.
-Button rifled with match tooling as opposed to production tooling, resulting in bore and groove tolerances maintained within .0002" for bore diameter and deviation over the entire bore length.
-1:8 twist 5R rifling.
-223 Wylde match chamber and bolt matched for optimum head space and accuracy
-Mid length gas system
-Black nitride finish for increased wear and corrosion resistance
-Nickel boron barrel extension, allowing less lubrication and reduces premature wear and friction between bolt and locking lugs during cycling. Slow or high rate of fire compatible.
