Green laser for a gun?

I wanan get a about 10-35mw green laser for my gun and i dont really wanna spend that much anybody know a good one? im afraid that if i just mount any random one that the crystal will get disaligned or somthing.


thanks in advance

Depends what caliber you are planning to use it for.
If it is for a pellet gun, get the cheapest one you can find.
If it is for a shotgun, you will want to spend a lot.
The recoil is the main determining factor, if it is made cheaply, it will bounce all over the place and might, as you say "get disaligned"
You have plenty to chose from online, here in Canada the selection is a lot worse (or costs a lot more for shipping) but at least we don't have the 5mW limitation you do.
Getting a 10-35mW laser might be tricky from a reputable dealer just because it is illegal to buy/sell them there.
