Sold, thanks for looking
This rifle is a factory built Rock River 20” A2 1:9 upper with 20 rounds through it in excellent condition, on top an unfired Cavalry Arms polymer lower.
Sold $670 shipped to your FFL
The polymer in the receiver is Nylon 6, which is tough stuff used in many semi-auto pistol frames. These have been substantially upgraded from the first generation polymer lowers. They are in production as Eagle Arms/Armalite lowers, and retail around $300 complete. These receivers are often used for pistol caliber AR conversions, using Olympic .45 uppers and Hahn mag blocks which allow the use of unmodified grease gun mags. The receivers have a lifetime replacement warranty from Cav Arms against defect, and would also be replaced for $30 in the unlikely event you manage to break it in the course of use, earthquake, experimental modification, whatever. Currently the most popular applications of these Cav Arms lowers is in superlight rifles (less than 6 lbs with the Bushmaster superlight upper), but they mate up just fine to Rock River and other uppers as well.
