Daniel Defense Lower Receiver Parts Kit, 223 Rem/556NATO, Black Finish 05-013-21007

Daniel Defense is proud to offer this kit for those interested in assembling their own AR-15. Although there are many manufacturers of so-called MIL-SPEC parts, we have gone to great lengths to ensure the parts they provide are of the highest quality and compatible with a wide assortment of available receivers. However as they have developed this kit we have seen a wide variety of lower receivers; some from “manufacturers” of questionable quality. Consequently some of Daniel Defense’s parts may not fit properly in some of these receivers. Daniel Defense always recommend purchasing the highest quality parts available to assemble your AR-15.
