Introduction: MSMG

About: I make K'nex guns, specializing in semi-automatic, RBG-Slingshot hybrid systems which i use in most of my guns. Note: I am not responsible in any way for any damage, injury, or death caused by my Instructable…
This is my MSMG (Masterdude Sub-Machine Gun). It has a true trigger and like most of my guns is semi-auto (there is some controversy over the term semi-auto but according to me in K'nex it means that every time you pull the trigger, a shot is fired)

Pros:
-Strong
-Accurate
-Semi-auto
-Removable magazine
-Adjustable stock
-Rather easy to use
-Adjustable cheek rest (when stock is extended you can slide it where you like it)
-Looks
-True trigger

Cons:
-Handle might be uncomfortable for some people
-Can be hard to load at first (But becomes easier with some practice)

Step 8: Loading and Firing

This gun loads and fires like most of my guns like my MAR, MAR-2, MSAU, ETC. To load you first remove the magazine and put the pin in place, and then you insert the ammo which is shown in the image below. Then you insert the magazine into the appropriate place until it firmly holds in place. They you push the white rods over the ammo feed out to the side and you take the rubber-bands and hook them on the tip of the barrel and then on the spoke in the back of the gun. Then you push the white rods back into place and pull the pin out of the magazine. To shoot you pull the trigger.
