holy crap, thanks for all the good responses guys. Ive decided just to upgrade my metal non blowback mp5 I currently have and spend the money I would spend on a cheapy M4 on upgrades. I admit, I fell victim to all those flashy DMR youtube vids but you guys are right.
I am ordering some 9.4's from Elite in the states with some dean connectors. I am either going to just buy a complete Lonex gear box or the lonex shell and mix match some parts. I am going to upgrade my barrel on my MP5 to a 6.03 330mm. Only thing I am still considering is the motor. I am looking at the Lonex infinite high speed.
What you guys think? more realistic?
