It’s a G&G Raider poly receiver, V2 blowback gearbox (blowback disabled) and a full metal 13.5 Mlok rail. I was trying to replicate the Geissele URGI. Comes with gun, vortex flashider, hollow peq, mag, flip up metal sights and regular crane stock. Eotech, magnifier and Surefire NOT included. Price is shipped. NO trades.
