Things I liked:accuracy and power. Gas ram piston Things I would have changed:scope rail What others should know:Once you master the technique to shoot this gun, it shoots dime size groups at 30 yards. Trust me though, it is a difficult gun to shoot. It is very sensitive to your hold. The gun is awesome except for the fact that the scope combo is absolute garbage. I went through three different packages because the scope would not zero. Seems to me that the scope rail on the guns are not aligned properly. I got tired of returning the gun so I decided to shim the scope for now. I will need to invest in an adjustable scope mount though to properly fix the problem. The worst part though is that the email address of the tech that I was dealing with no longer exists. I'm not sure what Pyramyd Air is going to do about my situation though. They sold me a combo that doesn't work properly. I guess I was out of line to expect to be able to put the scope on the gun and use it right out of the box. I gave the gun one star on value and overall rating because what good is a purchase if you have to buy other stuff to make it work.
