I love my 882SS (.22 WMR Stainless Steel / Synthetic - 2 or more generations older than the XT version).
With the improved trigger system, it should only be better.
Pros:
They're just as accurate as the competition, rugged, reliable, affordable, and available.
The dovetailed receiver makes scope mounting easy, with rimfire/airgun rings.
This whole series of rifles has many interchangeable parts. Repairs are cheap, with easily sourced parts. (Though, you shouldn't ever break any thing.)
Cons:
Magazines stab you in the back, if you carry the rifle slung over your shoulder. (There is a solution, though: Buy the flush-fitting 4-round magazines from Marlin.)
Fit and finish are not great (it works, but won't win any beauty pageants).
The stupid airgun/rimfire dovetail on the receiver is a hokey way to mount a scope - they should have drilled and tapped it, too.
Bottom line:
I'd buy another one.
I'd probably even trade Old Reliable in for one with the new Fire Control Group. (I wonder if I can drop one in my rifle....
)
