Things I liked: NIce design and very well finished - all wood/steel except for endcap. Trigger is very useable - fairly crisp, well regulated, and decently light. Short, EASY stroke - kids can do it. Very accurate - not a total tac driver, but very good with a variety of pellets - eats cheap ones well - Crossman Premiers. Sights are very useable, and can give decent accuracy - but not precision some may want. You can STILL drive all rounds into the black at 5m with these sights if you do your part. Excellent for a basement plinker and for young shooters. It IS addictive - easy to cock accurate, nice stock, good looking - overall a superb deal and well designed. It WILL perform out of the box. I had no dieseling.
Things I would have changed: Provide a peep rear sight to bring out all the potential. While you're at it, provide a globe front with swappable inserts.
What others should know: Crosman Premiers (HPs) work well. Because you are at 500 fps or less, you will need substantial target backing and fire HPs or domes. Wadcutters at these speeds will tear a big hole in the paper. I DID have to slightly adjust the rear sights. Notch ONE is good for 10m, notch 2 for 5m.
