Lower Rail for SMG v5

I felt the gun is a little uncomfortable with pretty much all the weight behind the grip. So i wanted to attach a vertical grip. Instead of designing one just for me i thought i'd rework the rails which are already a part of the project.

To assemble the rail, you need 3x13mm+ m3 screws and 3x m3 nuts. You don't have to dissassemble the whole gun to apply the rail. Just unscrew the 2 M4 screws holding the front handguard piece. Apply the nut holders on the inside and screw the rail in from the bottom.
