Who is PK? His resume is likely already on your rifle. His name is on countless patents from his time at Surefire. Many consider him to be the Da Vinci of tactical lights. After nearly 2 decades he left his role as VP of Engineering and started his own company: PK Design Labs.

The PKDL PRX (aka, the “Rocket”) is simply the best weapon light on the market. It is fueled by a single CR123 and outputs a banging 550 lumens. It mounts to any 1913 rail with a spring loaded screw clamp. The light rides with a low enough profile when mounted at 12 that it will clear lower 1/3 sights (scopes, red dots, etc) with no issue.

The light comes out of the box with a click cap on the rear. Soft push for momentary, click for constant. The light is designed with a lock out function - quarter turn the tailcap and it will disable the light from any accidental activations. The light is also compatible with the full suite of Surefire scout based tailcaps and pressure pads if you purchase the additional adapter.

If you want the smallest, most compact weapon light - you’ve found it.
