I bought it for the cheap Sig 522 gun and din't want anything that cost more that 25% of the gun. The coolness factor of the gun demanded cool looking red-dor sight. Well I found it. It works great fro plinking. It would be hard to place good shot in a hurry, but if you know where you cheek should be it works. The original front sight for the rifle is a big help, since putting them together in line will assuree hit up to 50 yards in Cola can. Good purchase for any "toy" gun. I would not put it on any gun with recoil, since the sight made of light plastic.
Pros: cheap, nice looking, good for airsoft and paintball, fun too shoot
Cons: plastic, fuzzy red-dot, not precise
