Rainier Arms Ultramatch .223 Wylde Rifle - 18"

AR-15 Rifle


The UltraMatch™ Rifle 18" weighs in at 7 lbs and 2.5 oz. We wanted to build our rifle by using Rainier Arms Ultramatch™ 18" Stainless Steel Barrel. These barrels are the finest blank contoured to our specifications for reliability and accuracy shooting. As always, we designed the rifle to be ambidextrous to accommodate our shooters. Every rifle comes with a Rainier Arms Avalanche Charging Handle, the built in ambidextrous bolt release, and ambidextrous 50 degrees safety selector. All materials used are of industry-leading standards, each weapon carefully and meticulously assembled with a limited lifetime warranty.
