nice "frogboy" ignition system (2nd time that phrase has been used in 1 day) not a good idea to have the ignitor in the cap, if you set the gun down it'll go off, and the endcap is the weakest point, if it fails, your hand is right there, plus the ignitor might rocket out and leave you with a very injured finger, next time use screws as electrodes and mount the ignitor outside the gun with wires running to the electrodes
