Things I liked:The first time I shot this I was holding some good groups with the provided sights. Great feel to the gun and not to hard to cock with the assist handle. Things I would have changed:It would be nice to see this gun available with the Nitro Piston option if they could do it. What others should know:I did as Paul said in the video for the 800 and bought the Walther Top Point 2 red dot sight and 1 inch Accushot rings. I had my local gunsmith drill a stop pin hole and mount the scope for around $60 what a difference it made I'm now shooting three quarter inch groupings at 35 feet. This is a great airgun in 22 caliber with the provided sights or the red dot scope this is a real pleasure to shoot. I'll be enjoying this for years to come. Thanks Pyramid!
