Things I liked:Pyramyd air's excellent service. Things I would have changed:Breech seal, sights, trigger, rail, and wood. What others should know:I have owned three gamo guns and all of the have had problems within 5 months of purchase. The breech seals on gamo guns are a big problem, they rip, crack, and fall out. Save yourself some money and go for a RWS or Beeman.
Things I liked:Light weight, Synthetic stock, power, and accuracy. Things I would have changed:The Trigger pull is a bit hard so it is hard to get good groups. What others should know:I got the .22 cal and it will take down a squirrels, chipmunks, raccoons, and rabbits easy. So far i have shot 1/2 groups at 20 yards and 1 inch groups at 30 yards.
