I think you'll be extremely happy with a Maximus. You'll also get addicted to just being able to load and shoot between pumping, then you'll decide pumping isn't any fun and get a tank, then you'll decide you want more than the Maximus, or want a better scope, or, or, or.
As for the bolt, don't think you need to worry about it breaking, but that upgraded bolt will work well, and you have to be confident in your rifle, or it takes all the fun out of it.
Even though I plan on buying an FX later this year for my second rifle, the Maximus is soooooo tempting I may buy one anyway.
So which did you buy, the .177 or .22, and I assume the full powered US version, not the European version?
Oh and if you buy off the Crosman site, do use the AGNATION 25% off code. It provides feedback to Crosman that their customers are using this site and saves you $$. That $350 kit with a pump becomes $265! Free shipping on Fridays.
Welcome to the addiction.
