Hey guys I I've been looking for a few months for a couple things for my MP5 SD5. I can barely find any type of equipment exclusive to the mp5 SD, basically all ive seen is 1 RIS module on redwolf, and a custom type batery for the fore grip. Another thing ive been trying to do is since there are few accesories for the sd, try to convert it to a regular A series MP5. anyone know how to do this? and one last question, ive looked on mechbox.com and theres no place that tells me how to re-wire the gun for a battery at the front instead of the back. help??
