However, I'm not too sure of what to exactly use on a "scaled down" spudgun. Do you guys have any suggestions to the overall design of the gun? Variety of parts here are sort of limited as my country is more "consumer-oriented" if you get my drift..... My concern with the gun is that the PVC might not be able to withstand the heat of the combustion (Will it?) Rough drawing of plans...... Might try and make a semi-auto plan.....
