I'm pretty sure I'm in line with the law as far as I'm concern, curious where you get that citation from?Sounds like you are walking a fine line here of manufacturing an explosive device without a license. I realize it is a very small device, but it you mix the chemicals in a large batch before dispensing it to the individual primers, that might be an issue. But I'm reasonably sure the ATF is busy rounding up all the 14 year olds that are putting full auto switches on their glocks so you should be GTG.
