"NMshooter"I really love the Marauder platform, that said, either caliber may not come out of the box shooting well. This can always be corrected and that is where the learning begins. I got an education with both of my Marauders and ended up putting around $300 into each rifle (well maybe a little more). You will need to expect to do this or you may be very disappointed. From what I have read, more people have better luck with the .25, however, I was not one of them and 16 shots SUCKS. I replaced the barrel, transfer port, Hammer, and added a Regulator and theTSS to get it shooting well (geting 28 good shots now). I was planning on doing it so I was OK with it. Shot 2 P-dogs at 104 yards last time out hunting and it is turning out to be a shooter. The Marauder is one of the easiest rifles to work on and there are lots of videos. I am by no means accomplished working on these things but it is getting easier. You can also pay someone to install these as well.
If you are looking to fill up a rifle with air and start shooting bullseyes, I might suggest saving up and purchasing a Daystate Regal (in .22) or an FX Streamline (either caliber). Both can be had for just under a grand. The Regal really has a nice wood stock. It is not regulated but does not need it. You can get the Streamline in wood but you will be over a grand.
I really am not trying to talk you out of a Marauder (as I have 2 of them), but plan on doing a lot of homework if it doesn't shoot great at first. Good news, there is lots of help out there.
Best of Luck with your decision!
