Locally Sell a Medium to High Power Laser

Hi all,

I was wondering how legal it is to locally sell a like within a town not shipping it anywhere.

Im asking this because im thinking about selling a 300mW red 650nm im made recently, to a friend. We've been friends since elementary school and he's responsible enough to trust him not be stupid with it. He will be responsible for his own eye protection, ill tell him exactly what needs but he will have to buy it.

As it stands now, im not doing anything until I understand the legal terms.

So far, I have only managed to gather this from searching this topic around:

1. Any with optical power output must have the required safety features on it like key locks, led to show the is on, and a certain delay until the actually turns on.

2. It is legal to sell any of any power as long as proper safety requirements are met.

3. The must meet the stated output power within a stated tolerance to go along with quality control and false advertisement.

Im sure this is not all correct, but if it is, what are all of the safety requirements, if I missed any that is.
