Rival Arms RA20G802E Precision V1 9mm 4.17″ Barrel

Rival Arms RA20G802E Precision V1 is a match-grade drop-in barrel designed for compatibility with the Glock 48 and 9mm Luger. Machined from stainless steel and finished in Gold PVD, the 4.17″ fluted, threaded barrel combines durability with precision-oriented features. The bore receives a BORSLICK Boron Nitride DCD inner treatment to resist heat and carbon buildup, and the muzzle is target crowned for consistent bullet release. Threading uses 1/2″-28 to accept a range of aftermarket accessories, and the barrel installs as a drop-in with no gunsmithing required.
