All Kies billet lowers start life as a solid block of 7075 aluminum. Kies Firearms does not use castings or forgings for their billet lowers, these lowers do take more time to produce but they feel that it delivers a superior product as all dimensions are held by the CNC machinery and are not dependent on the condition of a forging die. Kies billet lowers also feature extra wide and deep magazine guide surfaces, common in many competition AR-15 lowers. The front magazine wells are also checkered all the way to the edges offering a superb grip when using a mag well hold.  These lowers also have an permanent winter trigger guard. These Lowers will work with P-mags
