Hopefully no one will confuse "AMC" with that crappy little car company of the seventies. What did you use for the chamber?

in the upcoming presidential election, there will be several candidates who will be running, one of whom is Hillary Clinton. Now WAIT A SECOND!!! I though there was some sort of rule that prevented someone from serving more than two terms in office. Vote Against Hillary: Presidential Elections 08

the word marble is in the title, judging by that i woud guess that his preferred projectile is a sock filled with sand.

Hahaha nice one beebs.

Hey f.c not to bring you down but since your using propane do you have a metering device or do you just spray and pray? Also you might have wanted a longer barrel for that beast. you'll get better performance, but hey do what works for you man. Oh and cool cannon by the way I like the green and black
