I have for sale, 1 Rock River complete lower receiver. It featured a collapsible stock and a two stage trigger. The lower is very lightly used, aprox 90 rounds fired. It is jet black and the fit/finish is excellent. It mattes perfectly to LMT and Colt uppers that I have tried on it with no rattle at all.
Price is $325 delivered to your FFL. As always, please verify that this item is legal to own in your area. It is not for sale where prohibited by law. PM me for pics and with any questions.
