Thanks for you help and info guys. Not knowing what is a good make/brand for upgrade parts i guess i went for the cheapest, lesson learned! Another question - i have removed the selector switch to lock it to semi use as a dmr, but if it locks up i used to just switch to full auto to clear it. I cant do that now. Whats the best way to stopnit locking - full press of trigger not spamming it, or would a mosfet stop this? If so what mosfet do you recommend?
