Things I liked: Value for the money. Pretty accurate at 10 yards, not bad at 20.
Things I would have changed: The scope. The 4 x 15 scope it comes with is the worst. scope. ever. I swapped it out for a Bushnell 4 x 32 Rimfire and am pretty happy.
What others should know: At 10 yards, Crosman Destroyer EX gives very good groups. At longer ranges they really give a shotgun pattern, though. Crosman Premier Hollow Point is much better. Max effective range seems to be 25 yards, and even at that distance I probably miss more squirrels than I hit. 20 yards might be a better number for effective range (allowing for the fact I'm a n00b and not a good shot yet). At the 50-yard distances that I'm currently dealing with for ground squirrels, I'd be better off throwing rocks at them. A really good shot might be able to hit one at that range, of course, but still, this just isn't the right weapon for that distance. If I'd known as much a couple months ago as I know now, I would have bought a gas piston rifle in the first place, but I do plan on getting one. I'll teach my kids to shoot the 880. Like I said, it's great at 10 yards, and they can start there.
Things I liked: Stunning accuracy - I just sighted it in today and shot a dime-sized four-shot group at 25 yards using a bipod resting on a lawn chair - and I'm not even a good shot, I'm still a beginner. This thing is amazing! If I can do a group like that at 25 yards, a good marksman can probably put four in the same hole at that distance. As it was, three of the four holes were touching each other and the fourth was just a little bit away from the others. All were in the center of the bullseye. Very, very quiet - the ping is louder than the report. Excellent fit and finish, this is a really well-built gun. The trigger - it's wonderful. The pull is just right for me, I have no plans to adjust it. Both the first and second stages are very smooth and precise. Made in USA (with some imported parts)
Things I would have changed: The ping is annoying, Crosman should just de-ping these things at the factory and be done with it. It's pretty heavy. Weighing in at over 7 pounds, plus the scope and the bipod, it's a lot of weight to haul around even in my backyard. I'm 5-9 and small-framed, it's really hard for me to shoot a Marauder off-hand.
What others should know: I ordered the Marauder .25 Ultimate package and it's a very good value for the money. There are, however, two things I would change: 1) Include at least a 4-16X scope with it. I went out and bought one anyway and will eBay the Tech Force 4-12 it came with. The optics on the Tech Force are a bit better than on the Crosman Adventure Class 4-16 I bought, but I really wanted the extra magnification. 2) While I didn't have trouble installing the bipod as some Marauder owners have, I do think that overall it's a piece of trash. It's too short to use for anything but firing prone or from a bench; I can see already that I'll be buying a decent bipod that extends enough to shoot from a sitting position. Pyramyd has put together a nice package overall in the Ultimate package, but they should really drop this bipod and either make the package cheaper or put the savings toward a higher-zoom scope. The bottom line is, get a Marauder, you'll love it :-) It's everything people say it is and then some. I upgraded to this from a Daisy 880 (really!) and considered a number of gas-piston springers before settling on the Marauder. The more I researched, the more I could see that if I didn't get a Marauder, I'd wish I had and would find myself shopping again in a year, anyway. Crosman has a synth stock version of the Marauder coming out in the fall. If you want something a bit lighter or just prefer synth to wood, it could be worth waiting for. I just couldn't wait :-)
