I'm not sure what you've heard about accuracy issues. Crosman did receive a batch of .22 barrels many years ago which had virtually no choke. However that is not the case now.
What you HAVEN'T heard is Crosman assembles AND accuracy test each rifle before it goes out the door and the test target is included.
That's called Quality Control. Their Customer Service is second to none. They answer the phone or return your call promptly, they speak English as a first language and they are genuinely nice people.
Umarex doesn't do that.... Hatsan doesn't and Gamo doesn't either......
And in .25 I think I read or heard Crosman makes their barrels in house now. (If this statement is inaccurate please confirm). They were using Green Mountain to make their barrels only for the 25.
The .25's I've had in both Gen 1 and Gen 2 have been stellar performers. Yeah, they aren't regulated but can be, the shot count is around 25 as a result (and BTW by installing a reg you will give up some power for more shots)
And as was mentioned, the trigger is one of the best on a gun under a grand.
If you do decide to get a Marauder..... get the JSB .25.39g and just shoot it.... Fill it up to the recommended 2700 psi for best power curve and enjoy. If it ain't broke,.....
IMO, great value. You don't see them for sale used hardly at all. Wonder why????
