I have an idea get a WE g18c put in a ra-tech 6.01tbb and a reaps bucking. Then get a roni kit put the Glock in that and you will be good to go. The WE G18 with those minor upgrades is a kick ass gun. The plus side to this is you can do it all under $200 you will have a pistol and an smg and you will most likely have something no one else has that day. Haha in all honesty the WE G18 with the tbb and reaps bucking is amazingly accurate for a pistol and shoots forever.
