That would be an interesting feat....
Hiding a 10kg, 4foot long machine gun in a 5 foot long bike....
Or a 6foot long assault canon on a 5ft long bike....

Why, oh, why is there no "like" system on this forum?
In all fairness it is a pretty sweet gun. Normally I'd be pissed that the plane was being reduced to the category of accessory but how else are you going to be able to use a gun that awesome?
