Alpharex here, with my latest creation!
It is the new Assault Rifle!

Pros: Light, Small
Decent Range
IT FIRES WHITES! GASP!
Uses little parts
Large Mag
Mag doesn't jam
TRUE TRIGGER! :D

Cons:
Bad Handle
The stock may make pulling the ram rod back difficult. (That's why the Stock is optional.)
Mag Pusher Sticks out of the Gun.
