Things I liked:The gas spring. I don't think I will ever go back to a standard springer. Thumbhole stock is nice, and the gun has good balance. Not as hold sensitive as a standard springer. Noise reducer works well. Now that I have about 1500 rouids through the barrel, it has become quite accurate. Things I would have changed:I HAD problems with all the following and changed them all - trigger, scope, mounts, flashlight, and front and rear sight. The trigger was anticipated, but not the other problems. What others should know:With all the problems, I still think the Whisper is a great gun. However, I would get the standard version, unless you have to have the thumbhole stock, as the scope and accesories do not work well together with this rifle. First the scope does not have A/O. So if most of your shooting is under 50 yds, you are limited to 3-4X if you want a clear image. In addition, the front sight & silencer obscure the scopes vision. You can't even use the flashlight, as the flashback into the scope blinds you. Even after removing the front sight, you still get a small amount of flashback from the silencer. The Standard and Deluxe Whisper come with a mounting rail for the scope, and this should be include here as well. I had to go to high rings before I could get a clear sight picture and use the flashlight. The flashlight was good to probably 20 -25 yds.
I also had problems with vertical stringing while shooting the open sights. I never could figure it out until the rear sight came apart for a second time. The rear sight had to be raised quite high in order to sight in. This is because the front sight is mounted high on top of the silencer. So their was no tension in the tension spring in the rear sight, and it worked loose after about 50 shots. If you want to use these sights, then you will need to loc-tite the rear to hold your settings. I just removed them completely when I mounted a new scope and light.
Things I liked:Excellent, excellent pellet. I now use this exclusively for training in my Steyr LP10 and Aeron Chameleon. Performs as well or better than all other match pellets I have tried, except for Vogel.
Things I liked:For the money, this is the best quality pellet available. And I have tried just about everything. I shoot a lot and go through 30,000 to 40,000 a year shooting 10 meter targets, using a Steyr LP10. So I want a low cost quality pellet, and this is by far the best. They are the perfect practice pellet for the 7.0 grain competition pellet by RWS, the R10. Things I would have changed:Nothing. Great the way they are.
Things I liked:Uniformity. A quality pellet. Things I would have changed:Nothing. What others should know:Maybe a little expensive for just plinking, but if you are shooting competitions, these are great.
