Delta Armory M4 AEG

So this rif has not got a single original part as I’ve built this from the ground up. It’s got a complete new gear box, maxx hop unit and a improved motor (can’t remember the brand)
It works but i haven’t used it in a hot minute so might need a tinker just incase. Good for anyone looking into tech or need a start up gun.
Will come with 1x mag.
