A3 Tactical bullpup chassis with Foxtrot Mike's FM-15 bufferless upper and CMMG milspec lower. Upgrades are folding charging handle and additional recoil spring for shooting suppressed. Rise 434 trigger so no typical bullpup trigger pull. Nice and crisp. $1,000 or trade for high end MOA optics, Ruger MKIV 22lr pistol, or Buck mark 22lr with threaded barrel. Located in Rapid City, SD but travel to Williston, Bismarck, Dickinson, and Mckenzie often
