They are definitely good rifles, BUT! There is one poorly designed part in them.I have been trying to buy a good one for $600 for about a year now, and still can't find one. I have been told that Rasheed's are a good gun to buy from someone after test firing them at the range, and that there is some risk in buying them without knowing if they have issues or not.
Actually, it is the rear sight slide that is weak. The leaf is pretty tough. They made the bottom part of the slides a little thin, and then they drilled a hole in the middle of the thin part for a retaining screw. the slides will bend and, over time, get metal fatigue across the bottom fairly easily, and like Kennedy said, they can break.the rear sight is also week, do not let it snap down, it will break, I know from experience
