DoubleStar AR-15 Lower Parts Kit 223 Rem/5.56 NATO Black

The DoubleStar AR-15 Lower Parts Kit is a set of internal components and a pistol grip for building out an AR-15 lower receiver. It is intended for use with AR-15 platform firearms chambered in 223 Remington or 5.56x45mm NATO.

The kit fits AR-15 small pin lower receivers and comes in a black finish. According to the retailer's description, it contains every part that fits inside a lower receiver, including the pistol grip, and uses U.S. GI specification parts.

Because the kit is sold as a lower parts set, it is suited to completing a lower receiver build rather than serving as a stand-alone firearm.
