Things I liked:Nice gun, nice design.
And for the dollar amount paid, not a bad product.
Trigger is cast steel, not a stamped sheet metal part like the old gamo's
Automatic, and ambidextrous safety, you don't even notice it after 5 shots, but you are using it every time.
Deep rifling (on the .22 atleast) leaves consistent deep grooves in all lead pellets. Things I would have changed:Ditch the 4x fixed scope, its not what this rifle needs.
If they had spent just a few more moments deburring this gun before assembly it would have put it in a whole other class.
I had razor sharp edges on almost everything.
Also they GRIND on the cocking lever AFTER the gun is assembled and it leaves metal filings all in the action! The grinding is done to the part of the cocking lever that acts on the automatic safety (which IS a nice feature) in order to set the proper throw length. Anyway, get these filings OUT of there if you do nothing else, as they will only foul up your piston seal.
It's gonna diesel until you get the light weight oil off the spring and piston body, and replace with a moly lube. The reason for this is that it is not just burning off oil that was in the cylinder from assembly, there are likely cuts in the piston seal, as there were in mine, that allow more oil forward into the chamber.
What others should know:This gun will shoot fine out of the box, but can be made 10x better by getting the working surfaces deburred and lapped together, everything from the cocking linkage to the rough sheared sear surfaces.
Pay for pyramyd's chrono test, it's not expensive and if the gun is doing something funny, it won't be sent to you.
