The Rival Arms Precision V1 Drop-In Barrel (brand part no. RARA20S201C) is a 4.25-inch, 9mm Luger replacement barrel machined from 416R stainless steel and finished in bronze PVD for the Smith & Wesson M&P pistol, excluding the M2.0 generation. Rival Arms precision-polishes this barrel with 6-groove rifling and a low-temperature vacuum PVD coating for wear resistance, then adds a BORSLICK Boron Nitride DCD inner bore treatment to resist heat and carbon buildup along with a target-crowned muzzle for accuracy. It is a direct drop-in upgrade for M&P owners who want match-grade performance without a gunsmith visit.
