Mounted with a pro tac hlx - Streamlight M-lok Mount For Pro-tac Rail Mount Lights

This is a great mount, especially for the price. I mounted it in the 11 o'clock position with a Pro Tac HLX at the last mlock at the front of my handguard. With an inch from my handguard to the end of my barrel threads and the addition of my muzzle device, it brought the light to just about a half inch behind the end of my muzzle device which is fine for me, no splash whatsoever. The mount is solid but it is important to note, when mounting in the 11 o'clock or 1 o'clock, with the way the Pro Tac HLX is flared at the side where the screw mounts, one side will get in the way of attaching things to your top picatinny. So I marked with a sharpie the area I needed to clear and grinded it down flush to the mount with a bit of a bevel inward to be sure i would have amply space between my light and my top rail attachments. I used a dremel with a metal grinding bit to start and get the bulk of material off and a low grit sand paper bit to finish it. Covered it with some paint and the look and fitment is perfect! If you are someone who likes that clean, factory look, take your time and use higher grit to finish, but if you are someone like me who paints their rifles, you will never know. Overall, very clean and fits the light very tight to the gun. No complaints.
