Hello again from Germany BT Brothers.
Its me ram and i will show you now how to mod an A5 Opsgear UMP shroud that it fits on an BT-4 Assault.
At first i hope you can understand me and sorry for the distance data. They are in cm and mm (Europe), sorry i dont know what they are in inch.

Edited by Tomcat:     2.54cm per inch mate!

Before you cut, take a pen and make a line where you want to cut and file after all cuts

6) now its a little bit difficult, the numbers are there that you know where you have to cut, the distance between two green lines

7) with the shroud comes a (long) screw, which you need. Also you need a compatible nut and the the distance metal piece (you have cut out)

8) the weaver rails, you can mod it easily with a metal saw

If somebody wants to mod an UMP shroud, i hope he can do it now :)

That is extremely sick.  Ups to you Ram.
"We have barely recovered from the original Y2K. If you don't remember, seven years ago at the stroke of midnight, planes fell from the sky, the banking system collapsed and power grids caught fire from coast to coast. Or so I assume. I was locked in my underground shelter cleaning my zombie rifle."

Im wavering between the G36 and the UMP kits, seeing a finished UMP would help.
