Rainier Arms UltraMatch .223 Wylde Mid Barrel - 16

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. Features:

  • Stainless Steel Match Grade Shilen Blank

Barrel received did not match pictures on Rainer websiteReview by Dale
The barrel I received was not marked as pictured on Rainer's website. Barrel on website is marked 223 Wylde, Barrel I received was only marked "223". I appreciate the refund but I had to eat the return shipping as well as the original shipping on this and I disagree on that point since this was Rainers website listing error. By the way the barrel is still listed with the same picture. Not sure If I would order from them again. (Posted on 7/28/2016)
wow!Review by Richard
Could not imagine getting a better barrel for the money. Installed it on a mega mml upper and zeroed in 6 shots and then shot a 1/2 moa 5 shot group with cbc 77gr. ammo through a silencerco omega. Mega billet lowe with a ssae trigger. (Posted on 1/9/2016)
