T.REX Lightbar PRO Mount


Video | What’s Included | Specs | Pictures | FAQ | Related Info

A common problem with weapon lights once you start running a suppressor: Suppressor shadow – A large, oblong shadow obscuring a large percentage of your light’s spill. You lose some situational awareness and it splashes light off the side of your suppressor, turning it into a mini-Lightsaber. This PRO variant of the Lightbar was designed to extend SureFire PRO lights further down the rail, cantilevered over suppressors. This puts the weapon-light bezel more in line with the end of the suppressor, thus eliminating suppressor shadow and splash off the can. Short guns can also get cluttered quickly with pressure pads, weapon lights, IR lights, and IR lasers. Being able to extend the light further off the rail allows for more room on the rail.

Note: This will not work with the classic SureFire Scout footprint as it is specifically for the PRO series.

Why don’t you offer a KeyMod version?
To be honest, KeyMod doesn’t really sell. If you’d like to run the PRO Lightbar on your KeyMod rail, we recommend either getting a Picatinny-to-KeyMod section or picking up a KeyMod version of the Scout Lightbar and using the PRO adapter to mount your light.
