Daniel Defense AR-15 Platform Lower Receiver Parts Kit (05-013-21007)

We are proud to offer this kit for those interested in assembling their own AR15. Although there are many manufacturers of so-called MIL-SPEC parts, we have gone to great lengths to ensure the parts we provide are of the highest quality and compatible with a wide assortment of available receivers. However as we have developed this kit we have seen a wide variety of lower receivers; some from “manufacturers” of questionable quality. Consequently some of our parts may not fit properly in some of these receivers. We at Daniel Defense always recommend purchasing the highest quality parts available to assemble your AR15.
