Things I liked:Nothing -- the rifle was NOT operable out of the box. Things I would have changed:Poor quality control. Rifle was DOA out of the box. Would not cock even though it had a "quality control" sticker right on the stock at the hinge point.Obviously something wrong at the Gamo manufacturing plant. What others should know:Pyramid Air refunded the purchase with no hassles. I purchased a Crossman Nitro Venom from another vendor. Excellent gun, much higher quality - I will not attempt to purchase Gamo again.
