1. i'm not stupid
2. #1 being said, i'm not planing on building one *myself*, just designing it out for fun.
i saw the advertisment, and i thought it'd be a heck of a thing to see one of those in semi-auto
as for the problem of surmounting the heat buildup, i had also thought of using an electronic means of 'safteying' the marker. assuming you can use fairly standard board type components, it would be easy to hook up some sort of thermocouple or other temperature sensor to the same circuit the anti-chop eyes would be connected to in some boards.
to actually clear heat buildup away under high operation, heat sinking could work, and is probably the best option i can see at this time... at least until i install the fusion reactor with liquid nitrogen cooling.....
