"Excelent box. Does not come with motor so ull need an extra one. It pulls an m130 so fps is high. I recomend a .30 bb because .28 were still being thrown all over the place. it fits nicely but the rear body pin has trouble fitting in. Excellent overall with few problems

"This is a good gear box, I used it on an m4 with madbull tightbore and I got about 450fps now I am ussing it on my MP5 with a 120 spring and madbull tightbore and I get around 380 to 390 fps. I did have to change out slecetor plate, air nozle and the triger to get it to work on my MP5.

"If you plan on putting this or any other M4/M16 GB into a SCAR you have to swap the air nozzle and the selector plate. tried to swap this gearbox out of my friends s-system into my echo1 scar and i had to open them up to do it. great gearbox for the price.

"I am going to buy another one of thiese boxes.. But with a G&P Hopup Unit and a Madbull Tightbore Barrel it was 420FPS! with a Stock Barrel it was olny 390FPS. This is a Good Stong Gearbox Lots of parts are Strong and with a M130 You will have a high FPS and a Good RPM.. It should fit in a Classic Army Body Just fine..

"Question: would this fit on a Dboy M4?

Webmaster: It will fit "ALL" M4 series. Some modification might be required for certain brands. But generally, all M4 / M16 AEG Evike carries are Marui compatible. Thus, Yes, it will fit all DBOY M4 series AEG.

"Great gearbox for a quick swap out with whatever you have at the moment. If you have experience working with gearboxes, if you switch out the piston in this one, it'll make your life alot easier.
