This is my first post on here, so let me start off by saying "Howdy Folks". Now if you guys need some help on this project as far as 3D CAD work, let me know. I work with Solidworks on a daily basis and could maybe help out in getting the A5 guts to work inside a modified housing to look more like the M4. As I haven't yet gotten my A5 (its on its way to me know) I don't have access to to parts and pieces to model them up. I'll keep you informed as to when I could it and start modeling.
