The Rival Arms Precision Barrel (brand part number RA20P002A) is a threaded, match-grade upgrade barrel for the Sig Sauer P365, finished in black. Rival Arms CNC mills the barrel to precision tolerances for a tighter lockup and more consistent accuracy than the factory barrel, and the threaded muzzle is ready for a suppressor or muzzle device without further gunsmithing. It carries a 1:10 inch rate of twist and drops in as a direct upgrade, matching the factory-length 3.10 inch barrel used across the Rival Arms P365 lineup.
