I didn't get jipped on anything, I didn't buy it for the super low price of $300. Just one flash lamp or one of the "laser medium" slabs in it
would have costed $2000 new! If you looked at the link I give, you would see that my friend sold it for $2500!

Also, chemical lasers do need mirrors, argon ion (Ar:ion) lasers also need mirrors.

Plasma lasers don't need mirrors because the "gain" is so high that they don't need any feedback to get amplified again.
Now as rail guns go, they are not as complex as lasers but they also don't last as long even if its designed properly. Rail guns have losses and they
still need lots of power they can not be fired too fast without cooling and a new set of rails, which take time to load/install. A rail gun will have
its "one shot per minute" uses but will be surpassed by the laser when new, more efficient types are discovered.
Radioactive material emits alpha beta and gamma particles but it spreads out over distance, if a lens could be made for those particles then you
could really make a death ray!
