I recently just purchased a Micromag(Gen 4). I got it for a good deal because it is leaking out of the barrel(which means power tube oring leak usually).. I owned an automag way back in the day but never really tinkered around with it. I ordered a standard automag/minimag/micromag parts kit.. Anyways, I disassemble it and notice a purple power tube spacer and it has a blue bolt bumper..does this tell me anything about if it has a upgrade done to it(Level 7)? I know nothing about the level kits for these valves so any help is much appreciated... On the automag valve exploded pdf it show a blue bumper as level 7 bumper but i dunno if they all come blue and it shows the power tube spacer just brass....here are some pics of everything disassembled... Also I know you are suppose to replace the bolt spring once it sags below the bolt but does this spring change if there is a level kit installed? my spring inst lower than the bolt but it is smaller than one in the parts kit... pictures show difference.
Thanks in advance,
Luke S.
