Well, I'm starting fresh with AEG's, just picked up my first one and instead of buying a nice new expensive and good one, I want to learn about what I'm using so I decided to by a crap broken one and upgrade it. I picked up a used and abused UTG MP5-J. Already changed the front grip to a new grip with tac light, ordered a new metal CA cocking tube and cocking handle as it came with a broken cocking handle and bought a full stock with wires to replace the broken adjustable stock. I rewired her to the rear and want to run a larger battery in her. I was looking to run about an 8.4v 3000mAh battery and I've been reading tons about what upgrades to do and what needs to be changed from stock if I upgrade the battery, and I just wanted some input from the pros or people who have done it!

I know I'll need to do the spring, I'm looking to put in a PDI 120 or 130% spring or something of similar power, and I've read it would be wise to up the stock 15amp fuse to a 20 or 25. I've heard the MP5's are a bugger to get open cause you have to split the body completely in two to get at the internals but I'm willing to do it because I want to build a good gun and learn at the same time. Any other comments or recommendations from you guys would be MUCH appreciated. Thanks
