Things I liked:I am not a shooter, I was debating getting a .22 rimfire and start shooting at my local range when I decided to get an airgun and practice first. I therefore don't big range of experience to pull from other than the shots taken as part of a conceal weapons permit class I took. I like this Silent Cat simply because I was able to nail nice groups in quarter size groups at 20 yards right out of the box after watching the whole Airgun Academy video series. Next, I loaded up the platinum pellets from the package and improved that to groups in nickel size at the same 20 yards. These caught me by surprise with their loud reports. I like the iron sights and so far they have not wandered after 50 or so shots. I intend to tighten in short order to avoid drift. I am not bothering with the scope and instead worked with Justin here finding a good replacement scope. I will update later. Things I would have changed:I trust what most have said about the scope so, have opted to forgo installation and wait instead on a UTG scope. The trigger is also a bit of a challenge although I must say I developed a technique whereby I pull on secondary to a point just shy of the fire point and simply pull back the couple of millimeters left to fire: quickly and firmly and as squarely as possible. So far, so good. Nonetheless I have ordered the plastic trigger replacement for Charleythetuna and we will see if I can improve on the wonderful accuracy I am achieving thus far. What others should know:I had zero experience and still managed to achieve pretty incredible results at 20 yards right out of the box. So, this is a very viable machine for the beginner. Find the sweetspot on your trigger while maintaining focus on your target and it will come together somehow. Althought the PBA ammo beat the wad cutters, they are LOUD and it pretty much sounds like you are shooting a firearm. So, be warned.
