The gun which has had the same general concept to for two years.
A simple tube and stick rifle with a block trig system.
Powerful (can pierce 6-8 sheets of corrugated cardboard)
Fairly easy to make, simple in design
Compact and lightweight
Trigger is far away from the handle
Uses a few cut pieces (but good if you have already cut pieces and want to use them)
Uses so many !@#$%^& snowflake and half-snowflake pieces...
So yeah... I've tried to make this as detailed as possible, the yellow boxes with notes help, I hope. Have fun with it (if you have enough snowflakes mwhahaha)
For increased stability, replace all long gray rods with the harder black ones.
