Introduction: Failed K'NEX Bullpup SMG

About: K'NEX gun builder here at Instructables. More or less retired from the community, but I still pop in now and again.
Hey guys. Well, after BlackShadow12 posted his Failed bullpup knex gun, I thought I would give a try at making a Bullpup. There was only two differences that I wanted: 1) I wanted the mag to go in the top, and 2) I wanted a permanent for-grip. So that is what I did, and it failed (hence the title XD). The Pros and Cons are not entirely impressive:

Looks kinda cool (IMO)
It is a Bullpup
Trigger worked smoothly
New type of mag (I have yet to see a bent mag of that caliber)
It is comfortable
The for-grip was a great idea
The mag can either be set to go in the top, or up the bottom
Was not too piece consuming
Range: 30 - 40 ft.

Did not work
Handles were at a weird grip (I HATE handles at that degree)
Mech needed more room
Fake barrel was lame looking
FP hardly ever hit the bullets
Mech was on the outside
