For the Supernova pistol grip.....you have to remove the recoil pad an loosen the bolt enough to get the butt stock to slide back about 1 inch or two then you can just rotate it towards the top of the receiver. After the pistol grip is upside down you should not have a problem removing the trigger assembly.
I havent unscrewed it all the way but i imagine it would be a pain to rethread he bolt. Unfortunately, this step isnt listed in the manual. I have been told the manual was written before they offered the pistol grip option and never update.
As for the M2 tactical, I dont have a M2 but i believe that it is already tapped for the picatinny rail. Should be able to push the plugs out from the inside of the receiver. They only go one direction. I know this is true on the SN's. Then just screw on the pic rail.
Im sure that i have errored in my advice i will be promptly corrected.
Good luck.
If guns kill people....do pens mispell words?
