Introduction: K'NEX 40 Mm System V 1.5

Hey guys. Well, this is a new type of gun to instructables. It is "commonly" known as (or rather, not so commonly as) a 40 millimeter (mm) system. To learn more, see here. 40 mm systems are grenade launchers that, hence the title, shoot 40 mm grenades. The Mark 2:20 is a full-auto 40 mm system, and is found in many of the CoD: MW games.

Mine is a is a K'NEX version of a 40 mm system, but is not, technically, a replica of any particular gun. I just thought it would be cool to bring up a new "concept" to the K'NEX community on instructables.

Pros:
Looks kinda cool (IMO)
Has good range for a grenade launcher: 40 ft.
Has good close range power
Easy to handle
Has a pin-guide (you are welcome Knex.X) XD
Has detachable mag/inner barrel
Can shoot shotgun shells
Has handle guard
Might be useful in K'NEX wars
Has true trigger

Cons:
Trigger needs some help to block
Not a replica
Kinda difficult to load

Well, there you have it. The R40mm System. I would really like some of you guys to really just take this and use it to your advantage. It is my gift to you all. Have fun modding and looking.
