I believe lrf’s with 1250nm or greater are not regulated because that nm wavelength is eye safe regardless of power.
It’s the mw rating of the laser diode pointer/illuminator that has a FDA regulation.
I agree. I want an atx but the promises that are said about magnum bolts and parts is frustrating. At least D Tech and Lmt have good parts availability.
I’m curious to know as well. I have a LMT MWS that is having this same phenomenon. Maybe a high stress point in the barrel and after a small heat is dissipates?
Put both on low power against dark background, then make a decision. Not many mk5’s have illumination and you’llknow why that’s important for this style optic
