The Rival Arms RA20G512A Conversion Barrel provides a match-grade, drop-in solution for Glock 23 owners seeking reliable 9mm performance, engineered to fit Gen3-4 frames with a 4.02" Black PVD stainless steel fluted and threaded design that accepts 1/2-28 accessories for suppressors and compensators. Precision CNC-machined from 416R stainless steel, this barrel delivers exceptional corrosion resistance and durability, while a low-temperature vacuum PVD coating creates a tough wear-resistant barrier in demanding environments. Its 1:10 twist with 6-groove rifling ensures consistent accuracy and precision from shot to shot, and the BORSLICK Boron Nitride DCD inner bore treatment helps resist heat and carbon buildup for cleaner, more reliable cycles. The target crowned muzzle contributes to consistent muzzle velocity and flight, and each unit is individually hand inspected for accuracy before shipping. No gunsmith is required for installation, and Rival Arms backs this conversion barrel with a limited lifetime warranty, making it an ideal upgrade for shooters pursuing improved precision, reliability, and versatility in a pistol platform.
