Questions & Answers
would this be a good tactical flashlight to mount on a .300 blackout 8.5" Shockwave AR-15 frame pistol ? Expert Answer

As long as you use a universal flashlight mount and remove the pocket clip from the flashlight, then the Klarus XT21X Rechargeable 4000 Lumen Tactical LED Flashlight will function just fine. However, there is not a pressure switch that is compatible with this light. If you were looking for something with a pressure switch I would recommend Surefire Scout lights or the Streamlight Protac.
