Things I liked:Power, Accuracy, Precision, Durability, it's made well so to say.. power even at +100 yards and then some. Things I would have changed:It is very hard to cock! Seems a little awkward to get the needed cocking leverage with this package (scope mounted etc..) though I'm sure it will be nicer once it's broken in. It's a heavy rifle, I know, I have many pellet rifles and take hundreds of shoots every week. I'd only recommend this to a person who doesn't mind the extreme cocking effort needed. What others should know:Use precision pellets, tighten screws frequently (should be done to insure good integrity). My main target gun prior to this one was the Gamo Whisper .177, it's a great gun, 'cept I wanted a good .22CAL.
Things I liked:Accurate for sure. Good seals, manageable weight, decent scope, good long-ranger. I have the .177 version of this rifle. It's relatively easy to shoot free-handed. Got mine back in mid-2011. Things I would have changed:Not so much.. maybe install the "SAT" trigger found in some other Gamo guns. What others should know:I've been through 1000's of rounds with this rifle, and it doesn't disappoint usually. Frequent shooter here. This rifle recoils substantially, be sure to TIGHTEN EVERYTHING FREQUENTLY. It's never good to overdue the tightening process though, this could cause excessive wear on the threads.
