I didn't take my .22 XL apart as my chrony results indicated the seal in my gun is fine so I just left it the way it is, but the guys that have taken theirs down have said that you do not need a spring compressor.
Cocking effort..... I own a .22 350 magnum and my XL definitely takes more force to cock. The only other springer I have that takes as much cocking force is my English made GAMO 1250 Royal in .22 The cocking effort doesn't bother me though because it's not a target rifle, it's a hunter so it's not like I'll be sitting in the back yard plinking with it. The initial sighting in and pellet testing did of course give my arms and shoulders a workout, but now that that's done I don't give the cocking effort a thought.
My only complaints with the rifle out of the box was the HORRIBLE stock trigger, but that's an easy fix

, and the staining job on the stock. Don't get me wrong, the staining job isn't horrible, it's just poor - fair at best, but I must admit that once I cleaned it up and spent some time on the stock with a new silicone cloth it now actually looks much better. To be honest though the stock is fine with me cause I bought the rifle to go hunting with and it's gonna get its nicks and dings anyway so to me it's no real big deal.
The metal and bluing on my rifle was good,,,,not great but good,, about what I would expect. Again though, I bought this rifle to hunt with so I'm happy.
As for it's capability as a hunter for small game and medium sized game such as groundhogs....... the gun is simply outstanding
