"Got this guy to replace the gearbox in an 11 year old tokyo marui mp5 R.A.S. The sector gear stripped five teeth one day in the middle of an intense firefight, so I was a little bummed and I came on to Evike to get a replacement gear for it. I found no shortage of parts, but the more I looked at that old gearbox, the more I realized it was just worn away - I could've bought the new gear for sixteen bucks and have it fixed and maybe have something else go in a few weeks, or I could just save myself the headache of breaking down that mp5 (seriously, it's time consuming to open all those mp5 clones up, there's no way around it) and start from the ground up with a brand new pre-assembled gearbox (also cheaper here than anywhere else that I found, AND you know you can trust evike.)
So far it's working wonderfully and I have zero complaints. The wires that run to the motor are a little stiff is all and can be tricky to hook up to the connection terminals, but it's an easy fix - just limber em up a bit, almost like stretching a muscle - don't go too far, but loosen em up a bit. I would open it up a bit when you get it just to make sure that it's properly shimmed and greased (IF you know what you're doing, if you've never fiddled with a box before, just do your research first!). Mine was perfect, but lemons are bound to happen at least once or twice - particularly with gearboxes, only because they can require tons of finesse at times.
Anyway, highly recommended for someone looking for a standard plug and play box that's affordable and dishes out a pretty capable performance.
