Things I liked: wow. this air rifle is awesome! I use it for my JROTC unit for marksmanship, and I always shoot 250's or above with this bad boy. I love the adjustable stock,butt, and trigger. The cylinders are easy to refill with a tank, and the pistol grip is very comfortable. The trigger is very smooth and jerking doesn't mess up your shots very much, but it isn't recommended.
Things I would have changed: There isn't a safety button on this rifle, so you have to be very careful with it. I wish that they hadn't discontinued it. I'm not quite sure why they have, it's an awesome rifle.
What others should know: THERE IS NO SAFETY. You have to be VERY, VERY, VERY cautious with this air rifle. Also, the trigger is VERY sensitive. even after adjustment, the trigger was not as sensitive, but it was still sensitive. You learn how to get used to it after a while.
