UMG Project. Part 1

So, lets be clear. It's a Heckler & Koch UMP - Universale Maschinepistole - but, to G&G Armaments and Double Eagle, its a UMG - Univeral Machinegun - it's a copyright/trademark thingy.

Yes, I know I already have one of these. Your point is? Anyway, the old one is a DE one. The new one is a G&G. Or, I should say the new one is a G&G outer - basically the complete gun with a gutted gearbox for £58. The original plan was to build a custom gearbox as cheaply as possible and scrounge bits from the parts box. I was pretty sure I had a set of gears, several cylinders, a couple of piston sets, a selection of main springs and some 6mm metal bushes kicking about. I promptly ordered the rest but with an AK trigger rather than a UMP one. Why for? Well, I could get a UMP trigger but a V3 gearbox trigger actually is a two piece afair and the UMP trigger is just the trigger part. I'll buy the UMP trigger later. Of course, I discovered that the bushes had done a runner and I needed to order a set of those as well. They've now arrived and all the parts are here waiting to be installed. Here's the list.

Original G&G gearbox shell
G&P M120 motor
Lees Precision Engineering 6mm bushes
Guarder Polcarbonate Piston
Guarder Cut-off lever
Guarder Enhanced Tappet Plate
Element Gearbox Spring set
Element Silent Cyliner Head
SHS Spring Guide
Deep Fire AK trigger set

In addition we have, a Gearset, nozzle, polycarbonate piston head, trigger switch and an AWS mosfet. And, a spring, either an SP90 or SP100.

And, Plan B. Just in case none of this shit works I ordered a complete G&G gearbox posted from WGC for a mere £81. :) It was half price. Resistance was futile.
