I have little time to spare on my I'bles, so I've just uploaded the images to build the MBSMG-2. I'm afraid I can't add my usual instructions, but I hope that anyone building will be able to figure it out from the images. If anyone needs help just PM me.

Step 1: Main Body Parts

Step 2: Main Body Build

Step 3: Top Parts

Step 4: Top Build

Step 5: Put the Two Together

Step 6: Mag

Step 7: Use

It is operated very similarly to my other guns, so if you cannot figure it out consult my previous I'bles, or PM me.

Warning: This gun can cause damage and/or injury. The safety and other mechanisms can fail so always treat it as armed. Do not point at people, things, or animals. I am not responsible in any way for any damage, injury, or death caused by my Instructables. You are totally responsible for any damage, injury, or death caused by my Instructables. Use common sense when making and/or using them.
