Introduction: Working Knex M4 Carbine Model (not Full Scale, RBG)
An M4 Carbine I made out of Knex with removable magazine. The handle, sight, stock, and barell are all interchangeable, and I'm currently working on a SOPMOD kit to go with this.
(The picture shown here is short stock, short barrel, short gearbox, short trigger guard. The ratio of measurements is closer to a colt, but with a curved magazine. The newest model Has long everything except for barrel. The reason for this is because the longer the barell the harder it is to support it's own weight. The proper measurements being implemented in Knex [14.5 inch barrel, 33.1 inches total with stock extended] would be very fragile. The current model has been dropped out of a second story window with the only damage taken being an expelled magazine. Take your pick for which one you want.
