So Ive upgraded my dpms m4 ris that i got at the barracks. It was no longer shooting full auto, and semi only once in a while. It has a metal upper and plastic lower, and full stock.
I put in a mad bull 6.03 inner and got a shark hop up and bucking. I got a new mech box, 8mm matrix with a 130 spring. I got two motors both hi-torque hi rpm, one matrix 3000, one amp t5000L, tried them both, like them equal. I also got a mosfet to put in. Extreme fire.com ab long. It has active breaking and has sligtly increased my rof. I also installed low resistance deans connectors. when firing in full auto and you let off the trigger in a second the spring is automatically brought back and is no longer stressed.
It sounds like a totally different gun, cus it is. This thing really barks, much more accurate now, I can reliably hit a paper plate at 50 yards. It shoots about 80 yards with decent accuracy. Using .25 im only at 430 fps, was hoping for more. Battery drains alot faster now with the greater load from the motor.
