Rainier Arms Ultramatch PDW SBR

This personal defense rifle was built from the ground up to be the ultimate CQB weapon. We spent countless hours developing this system and spared no expense in designing the make up of this fine weapon. From the Mod 3 billet receiver set, to the Ultramatch 7.5" barrel, back to the Battle Arms Development PDW stock, no detail was left untouched.

The UltraMatch™ PDW SBR weighs in at 5 lbs and 15.4 oz. It features Rainier Arms Ultramatch billet upper and lower receivers made from 7075 aluminum.  We wanted to build our rifle by using Rainier Arms Ultramatch™ 7.5" Stainless Steel Barrel. These barrels are the finest blank (Shilen 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 Rainier Arms Avalanche Interchangeable Charging Handle, built in ambidextrous bolt release, and ambidextrous 45 degrees safety selector. All materials used are of industry-leading standards, each weapon carefully and meticulously assembled with a limited lifetime warranty.
