Excellent value - Streamlight M-lok Mount For Pro-tac Rail Mount Lights

It's no Arisaka, but it's definitely worth the sub $30 asking price in comparison.

I mean, it makes sense for SL to produce a budget aftermarket mount for their budget lights. Wish I'd found this before I went through several high dollar name brand mounts.

I like the way this fits the PT-RM 1 better than any of the arisaka mounts... gives the little recess for the step in the mounting base of the light to nestle down into.

Docked one star in the fit department, as it didnt quite seat tight down perfect to the Dark Hour Defense HG on my rifle. That said, I tested it on several other hg's and it fit fine. May not fit on larger diameters, though, YMMV. Also, the mount is a bit blocky in comparison to the Arisaka equivalent, but that's likely where you're saving your money.

I'd absolutely buy this mount again for any future SL weaponlight that can use it. I would absolutely buy the arisaka for something like a Cloud Defensive or Surefire light... though I think this mount would work there too, I just don't know why youd spend on the light and not the mount.

Save some dough with Streamlight!
