Check for and remove the lawyer spring in the trigger assembly? That made a huge difference in my Gen 1 Mrod. Don't have a Gen 2 to play with, but I am sure there is still one in there somewhere.
I think you will find the Gen II trigger better than expected and definitely better than the Gen I Marauder
I'm with you on the saving for a tank, when i got my Mrod I had only a pump and after the first month that was enough for me, that pump went straight to the corner and I went down to the dive shop and got me a tank. I also ordered a 4500 PSI 90 CI tank from PA. Never again will I pump up another AG, I also a few months or so after that purchased a Omega 4500 PSI compressor. If you shoot that Marauder much that pump will wear you thin on patients thats for sure!I ended up selling my Mrod and Pump but wish I still had the Mrod .25. Really loved that gun, very accurate and deadly on small to medium game thats for sure.I also did the Lawyer Spring mod on it and cut the trigger pull over 50%. Good luck and happy shooting.Willaim
