The Rival Arms Barrel for Glock Model 43 Twist Threaded Black delivers precision and reliability in a drop-in design, blending Rival Arms commitment to match-grade performance with practical, field-ready features for serious shooters. Crafted from CNC-machined 416R stainless steel, this barrel offers superior corrosion resistance and durability, enhanced further by a low-temperature vacuum PVD coating that resists wear in harsh environments. Its 1:10 twist with 6-groove rifling ensures stable, accurate performance across a broad range of ammunition, while the BORSLICK Boron Nitride Dynamic Compound Deposition inner bore treatment fights heat and carbon buildup to maintain consistent bore conditions round after round. The target crowned muzzle optimizes bullet release for tighter groups, and the 1/2-28 threaded design plus included protectors provide seamless compatibility with aftermarket suppressors and compensators. Each barrel is individually hand inspected for accuracy, and the no-gunsmith installation makes it a straightforward upgrade for the Glock 43 platform. Backed by a limited lifetime warranty, this barrel elevates precision shooting with a reliable, durable, and easy-to-install solution.
