-Doesn't use too many pieces
-Can have optional front grip and stock
-Rather easy to use
-Handle might be uncomfortable for some people
-Can be hard to load at first (But becomes easier with some practice)
More Instructables by me.
Note concerning problems in the earlier version of the MSAU: This is an improved version of my earlier MSAU! This version has the problems fixed! The trigger system is stronger and the magazine holds better to the gun. It still may disconnect from the gun by accident but it has been reinforced and will withstand most conditions except the most violent and strong movements during which the magazine/handle may disconnect from the gun.
Note concerning images: Image one shows the MSAU with optional additions. Image two shows the basic version. Image 3 shows version compatible with additions but without them.
