They are what they are,,, Not too bad with fixed sights.. I hope you get one that shoot straight, as in not left or right
Fairly easy fix.
They state in the manual (Do Not Fan) And beleave them, as I messed up the hand & timing doing just what was said NOT TO
All in all, if you take care of it you should have a good gun @ a good price.
Good Luck Shoot straight ; )
