Things I liked: the gun is realy durable. i'v gotten it jammed more times than i can remember and it still worked great. the gun design is perfect and the hopper (scope) can be changed with other crosman scopes. over all the gun is perfect for any level of airsofter.
Things I would have changed: only a few things i would change is maybe more rails on the hand grip.
What others should know: since the gun is fed by a gravity hopper so you need to shake it for it to fire, i usualy just shake the gun while firing
