Rival Arms, manufacturer of high-quality, modular pistol components for do-it-yourself firearm enthusiasts, proudly announces their line of match-grade barrels, optic ready slides, guide rods, and slide completion kits for Sig Sauer® P320 and P365 firearms.

 

Rival Arms is quickly being recognized by firearm enthusiasts as the leading brand of quality aftermarket performance components. As the company expands its product line with multiple Sig Sauer platform options, the goal remains the same — to manufacture handgun components that exceed factory standards in material construction, precision tolerances, and durability.

 

Rival Arms will offer standard and threaded barrels for the Sig Sauer P365, P365 XL, P320 Carry, P320 Full Size, and P320 X5 pistols. All Rival Arms barrels start with a stainless-steel billet to deliver maximum durability and are then precision CNC-machined to exacting tolerances to ensure the greatest possible accuracy before being treated with a PVD coating. This coating provides exceptional wear and corrosion resistance and is available in black or gold colors. Threaded barrels come with 1/2-28 threads for use with popular aftermarket suppressors and compensators. A color-matching thread protector is included for use without muzzle devices.

For those intending to use optics, the Rival Arms slides come ready with either an RMR® cut or "other" cut suitable for a range of popular handgun optics (Docter®/Noblex®, TRUGLO®, Vortex®, Burris®, etc.)
