I have an MX Double release trigger done by Phillips and it is bottom first. The trigger guarg and blade are Gold plated. No ser # on trigger . (( $1200 Delivered to your address in the Lower 48 )) Any questions please send a conv message for info and contact # - Thanks Bob
I had one done and bought one of Phillips he did to sell and both were Gold Nitrated "not Plated", I believe if you check with Phillips you will find it's nitrated. Hope that helps clear up some confusion... Don
