The SP-223 lower is made of 7075T6 billet, and is type III hard anodized black with Teflon coating. Our lower has features like no other lower on the market. Some key differences of the SP lower are the oversized winter trigger guard, quick access mag release, large front grip, and a nice beveled mag well opening. The oversized, built in trigger guard allows the use of a thick winter glove. The magazine release area has been designed to allow quick and easy access to the release button from any position. Also, the mag well is wider and elongated in the front for a sure grip as well as having a large beveled opening for fast, smooth mag changes. An upper receiver tensioning screw is located under the grip, and it also includes a captive detent spring to retain the rear takedown pin.
The Gen 2 Lower features an ambidextrous bolt release (Pre-installed)
*Because of the rear take down captive screw, the detent spring will need to be trimmed down.
