Things I liked: It's an absolute tack driver right out of the box. With the UTG/Leapers 4-16x44 SWAT Scope and JSB .22 Match Diabolo Exact Jumbo Heavy 18.1g pellets single hole groups at 25 yards are very common. The JSBs are so accurate I've only shot one other pellet (H&N FTT 14.66g) which were not nearly as accurate in my gun. Out of the box it was too loud for my neighborhood, but that was easily rectified with the addition of a barrel shroud (there are several good ones available as well as lots of other after market goodies for this rifle). I can shoot it on HPA on full power in my garage and you cannot hear it inside my house with the shroud installed. You will definitely want high scope rings with this rifle. Quality is top notch and the warranty is as good as it gets (Limited Lifetime). The power is very easy to adjust and it has more than enough power for my requirements. For less than $200 you can easily change the barrel length and caliber on this rifle in less than 10 minutes to go from a backyard plinker to a serious .25 cal hunting weapon. For the money this gun is tough to beat.
Things I would have changed: Trigger is very good, but not exceptional. It would be nice if it was adjustable. The forestock, grip, buttplate and safety could all be significantly improved. Again, these are all addressable with aftermarket add-ons (search Maddog Stocks). An option for a factory baffle for the SS barrel shroud would be great. In stock form the SS barrel shroud is just a hollow tube with an end cap. While it does make the rifle slightly less noisy, it could easily be significantly improved with a simple baffle. Better yet, it should be a standard feature rather than an option.
What others should know: If you are going to shoot it using CO2, the 12oz bottle is a much better option. The diameter of the larger 20oz CO2 bottle makes it nearly impossible to get a cheek weld and be able to see through your scope.
