DealRoyal Arms manufactures some of the finest Billet Lower receivers available today. Machined from Solid Billet of Aluminum, not just any grade of bar stock 7075 would do. Royal Arms uses a special blend of 7075 and had it heat treated to their specifications to make it more shock resistance and less prone to failure from fatigue and stress fractures. They then enhanced all the critical areas to make this one of the most durable AR15 Billet lower receivers on the market. It also features a Discreet approach to the logo and firearm information engravings on the bottom of the trigger guard. No big logos plastered on the sides! from AIM Surplus (Product F1RAK15) |
