If you are looking for a SOLID AR-15 build. This is one of the best lowers in the industry. I've had several lower receivers, but these guys put the quality in their product. I've bought 3 of their lowers, 2 of which I build SBRs off of. In addition, the price is right! QD also had a few customized options that really allow the AR to be mine (i.e. Laser imprinting and engraving options). Find a quality lower for a better price! I don't think you can. Thanks for doing business!
