So i bought this laser; www.rayfoss.com

It arrived like 2 days ago, and i really wanna try it out.
only the batteries won't be here for another week or so, i have some cr123 3v batteries spare from my spartan.
Would it be safe for the laser to run on these batteries (i've been warned by Rayfoss not to use them but im wondering if anyone has tried this?)

No, their smaller, so you'll need 2 , which will bump the voltage upto and over 6v , which will likely fry the driver.

300mW would pull a lot of current from a single cell, so I wouldn't recommend using a cr123 sized spacer either.

If you know anybody who services computers, ask 'em for an old laptop battery pack. Google how to safely extract the cells from it. You will then have 4-6 useable 18650's, though wit reduced capacity and/or performance, since they're old and been cycled many times already.
