This is a no-go if you’re using the FSB or a forward mounted optic. I just got them mounted on my 6450 and the bezel of the light completely blocks the sight path. There’s about 1/4"-3/8’ clearance between the light and the barrel, so it might work if filed out to allow the mount to sit lower on the FSB. I believe it would also work with the standard TLR-1 and possibly with the TLR-2. I just hung the light underneath and will return the mount. Just a FYI so you’ll know… Ron
I’ll confirm, the standard tlr1 has no issues on the mossie mount. Thanks foolproof for letting us know about the tlr-hp
