"Absolutely love these gearboxes. I have built 8 replicas and used them in each 1. The stock gears have held up to a DMR build with a m150 spring without any problems. I recommend them to anyone looking to build a custom replica.

"Gearbox is great but if you are looking to put this in a Tippmann aeg it will not fit.

"I bought this originally to fit into my Mp5 sd6 Cyma. Which I got it in there. Since the mp5 selector acts as the v2 gear box pin and the mp5 selector switch slider is the same as a m4 or m16 I had yo modify some stuff. I tried yo make a selector slide of gift cards. It would have worked well but the Ares gear box has a modified selector slide with a small magnet mounted to it ( for a hall effect sensor) I decided to not even go that route.

Instead I used a 6-32 screw and nut to take the place of the sd6 mp5's pin. I had a broken lower receiver for a m4. So I cut the m4 lower receiver and lined up the pin hole with the mp5 selector switch hole. And marked the position of where yo put the m4 selector on the mp5. I drilled the hole and made it to fit the m4 selector. Now it took a couple tries because the m4 selector hole was not exactly in the same spot yo engage the Ares selector slide.

So I have a random hole in my mp5 lower reciever. But on the second try I got it pretty close and it works.

The 6-32 screw gets in the way of the m4 selector switch because it is not flush with surface of the mp5 lower reciever. A little more effort and it will work great.

Not I used the gun with the Ares gear box installed yesterday. And it worked great. I like it to much because I plan on selling the mp5 and now I don't want to.
