I'm Just curious but where can you buy a K40 laser unit?

Yea, that would be the best option short of buying a K40.

@Eric_Flynn understandable, as I’m fighting Gearbest to get the part I need replaced at their expense via warranty. Cause so far I’m getting the impression that they are unwilling to admit they made a mistake and are now just trying to weasel out of making good on the purchase!
