Things I liked:As expected---Nitro Piston: more quiet, less recoil, more accurate; decent scope; hard hitting. Things I would have changed:Sling attachment points; Needs better trigger (replaceable, but at a cost); the plastic feels cheap. What others should know:Great value. Spoiled me as I will not purchase another springer that does not have an air piston.
Things I liked:Reliable. Extends your fun. Things I would have changed:Expensive. Have sales or allow for coupons. What others should know:If you're going to fill it with the Air Force manual air pump, be prepared to take a while...at least 450 full strokes for me.
