Best bang for the buck - Lasermax L Uni-IR Infrared Laser Sight

I just ordered my second one of these for use on 300 BLK rifles. Structurally this unit is fairly flimsy, but it works. The manual is available on line under Lasermax Uni. It supports seven different lasers in this class product. The rail attachment is well thought out so you don't lose pieces in the dark. Fits nicely in front of my grip pod. The alignment Allen wrench is very small and easily lost. Alignment is delicate. Best done with a visible laser already aligned and used with your daylight filter on your NVG to bring into alignment with visible laser. Battery compartment screws another source concern but functional. Works just great, good strong targeting dot. Went beyond my NVGs ability to resolve (>500 yards). Documented output power <0.7mW, Wavelength 800-900nm often cited in the center at 850nm. The slide switch can be an issue, inadvertent turn on can be prevented with care and an innovative fix of your own design. You need to know how to switch mode settings and practice it. Or spend another $150 for the switching kit. Great bang for the buck.
