Things I liked:Easy to bolt, light weight, accurate. Adjustable hop-up. Spent 'shells' eject. Things I would have changed:Bolt handle jiggles a little bit. If it was one with the bolt it would be better. Sometimes the thing you put in the breech to shoot the 25 round mag falls out into the breech and must be put back in, as all the ammunition pours into the breech. What others should know:Shoots straight althought sometimes shoots low to right.
