Rainier Arms Ultramatch .223 Wylde Rifle - 16"

AR-15 Rifle


The UltraMatch™ Rifle 16 is an AR-15 style rifle, weighing 7 lbs and 2.5 oz. It features our new Rainier Arms Switch™ Rail system - 14". 

The Switch™ Rail has a brand new mechanism that allows toolless removal of the rail for easy access to the barrel nut and gas block. 

We wanted to build our rifle using Rainier Arms Ultramatch™ 16" 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. Each rifle has a Rainier Arms Avalanche Charging Handle, an ambidextrous bolt release, and a 50-degree safety selector. 

All materials used are of industry-leading standards, and each weapon is carefully assembled with a limited lifetime warranty.
