Blackout Defense lower receivers are the ONLY receivers on the market that will stop the rattle, wobble, and slop in your rifle platform.  Our patented design incorporates aerospace-grade composite into a precision-machined groove to create a rigid assembly that is still easy to field strip.  In addition, our receivers are precision machined from billet 7075-T6 aerospace grade aluminum, which offers superior strength and rigidity over the more commonly used 6061 aluminum.  The receivers are then sandblasted by hand with aluminum oxide and hard coat anodized for a tough, matte veneer.  With modern and sleek design elements, this receiver set will change the way you shoot.
