I have a Sun Devil billet upper and lower receiver set, slick side upper and stripped lower. Both are brand new, never assembled let alone fired. I was going to do a lightweight build, but I've already got too many receivers laying around.$325 $300 OBRO for the set if we transfer at my dealer in Frederick, MD. If you're in MD and don't want to use my dealer, we'll figure out how to get it to yours at minimal cost. If you're out of MD, add actual shipping to your FFL. For payment, I'll take a USPS money order, or I can do a credit card (+3.5%)Edit to add some trades in no particular order (+/- ca$h as necessary):...Geissele SSA-E (would consider other models too)...backup reflex site, like a Burris Fast Fire, Trijicon RMR, Dr. Optic, etc....Surefire rail mounted light kit, prefer LED model (no 900 grip series)...Magpul UBR or PRS...Glocks: 17, 20, or 29, Gen 4 only please.or...anything else you might have, will consider most anything.
