If you liked the aggressive lines, cuts and edges of the Rainier Arms UltraMatch .308 billet receiver set, you’re gonna love the new AR-15 version of the UltraMatch Billet receiver set they are calling MOD 2. After releasing such an awesome .308 set recently, it only made sense to upgrade their existing AR-15 set to have a similar look. The new Rainier Arms UltraMatch MOD 2 AR-15 billet receiver sets are now available for purchase and will look sick on your next build. Pics and details below. Purchase now at www.RainierArms.com.
Our billet sets are CNC machined from solid billet 7075-T6 aluminum which is 70% stronger than the commonly used 6061 aluminum and finished with milspec hardcoat anodize to a surface hardness of 60 Rockwell. We have designed our lowers with an ambidextrous bolt release with extended latch for smoother deployment. The precision machining on our our billets are well known in the industry and we are excited to introduce our combo sets for your next rifle build.
