This was built as a dmr and works like one. Has an extended 6.01 mm barrel, upgraded engine (unknown) ~7 mags high and mid caps, magpul horizontal grip, mock suppressor for the extended barrel, 1 battery and charger, Magpul iron sights, (no scope) new grip and I believe a upgraded motor but I'm not sure cause I didn't build it my friend did and it was a while ago now. Price is shipped, US only price negotiable
