Things I liked:The six shot burst is guite neat. Things I would have changed:The gun is a bit large but fun to shoot. I wish the gun fed from the 300 round hopper instead of the 30 round magazine. The magazine does not fill very easily. It takes a lot of shaking to get the BB's to go in from the hopper. What others should know:I suspect many of the people who have had seal problems shoot the gun too fast. At excessive fire rates the expanding CO2 is probably freezing the o rings causing them to deteriorate rapidly. I have found the accuracy to be fine for a BB gun. You just have to hold back and not fire too fast and freeze the O-rings. I also put pelgun oil on the CO2 cartridges before inserting them to keep the O-rings supple.
Things I liked:It helps slightly. Things I would have changed:Needs an adjustable focus, not just a fake ring that does nothing. What others should know:Save your money. I'm sure you can find a better scope in the aftermarket for about the same price.
Things I liked:The price is good for a semi auto. Things I would have changed:The trigger pull is very long because its double action, advancing the next round before firing. That takes some getting used to, What others should know:You can get about 45 shots off before the velocity really drops off.
