Introduction: Knex Pump Action Gun

Picture of Knex Pump Action Gun

Hi, this is my pump action gun I made.
I built this because i do not see many guns with a string mechanism like this.
The closest thing I have seen to this is Mepains Shifle,now for the pros and cons:

High fire rate
Average range(30-50ft)
String operated

5 round magazine capacity
Quite big
Can malfunction

If you like it,Build it!


Step 1: Front Body

Step 2: Main Body

Step 3: Stock

Step 4: Ram Rod and Pump

My string length from the pump to the rod is 82 cm so it should be about an 80 cm distance.

Step 5: Connecting,Strings and Banding

you could've put more grey cons at the front to stop the pump from dangeling out of place and whats with the wheel? why does everbody always put wheels on the back of their knex gun?! or is it so it can be dragged on the ground like a suitcase with wheels?

The wheel makes the string slide smoother

It only shoots one shot, not a shotgun. And that pump looks scary, like it will break off with the smallest amount of force on it.
