Rainier Arms UltraMatch .223 Wylde AR15 Barrel 18 SPR Rifle Gas


We wanted to build an AR15 barrel using the finest blank and mass produce them to bring them to market at the most competitive prices. Our UltraMatch™ barrels start out as Shilen blanks and contoured to our specifications. We wanted the best balance between accuracy while keeping the weight down as much as possible. It also features Shilen's Ratchet Rifling™ which allows for flatter trajectories and easier cleaning. We are so confident in our UltraMatch™ barrels that we will offer a 100% money back guarantee within 90 days of purchase. If you aren't completely satisfied with the barrel for any reason, return it for a full refund, no questions asked. Now offering the same UltraMatch 18" Rainier barrel in MIDLENGTH gas (select option below).
