Installation and Operation Instructions

1.       Make absolutely certain the rifle is unloaded!  Visually check to assure a clear chamber, flag it, and apply the safety.

2.       Loosely thread the 2 provided, ¼”-20 socket head screws into The Original PuP Light Mount.

3.       Slide The Original PuP Light Mount all the way onto the rifle's gas tube.

4.       Position the flashlight into The Original PuP Light Mount to best accommodate your personal ergonomic preference.

5.       Tighten the upper screw with the provided hex wrench, taking care not to over tighten.

 6.       Raise the forward grip and tighten the lower screw, taking care not to over tighten.

Your Original PuP Light Mount is now ready for use! Thank you for your purchase! Always shoot safely, responsibly, and defend the 2nd Amendment!

Operation Information:

The Original PuP Light Mount was extensively engineered and tested to minimize thermal transfer to the flashlight and maximize heat dissipation via radiative elements of the mount itself.  It has been tested with several quality flashlights and batteries and easily sustained 240 rounds (6 magazines) of continuous fire at 1 second intervals safely, without fail.  In our opinion, this covers nearly all "Real World" situations. Please note, after several magazines the flashlight tube can get warm to the touch. If this is an issue for you, we recommend tactical gloves.


The Original PuP Light Mount is intended for use with high quality Hard-Coat Anodized ALUMINUM flashlights of the 1" size class.  The mount has been tested effective at holding flashlights down to .980” but using them could potentially permanently deform the mount and make it unable to accommodate 1” diameter lights thereafter. Do Not Use Plastic Polymer Flashlights of any kind! Use of polymer flashlights WILL result in the rapid deterioration of the flashlight housing and risk possible explosion of the batteries.

We recommend Lithium Batteries for the highest dependability.

The Fine Print: 

Use of the "High Gas" setting is generally attributable to neglect or severe battlefield conditions.  Though uncommon, should its use become necessary, it will result in high temperature gasses being vented onto the flashlight tube, discoloring the finish material.  By using the "High Gas" setting, you are acknowledging that a pristine finish on your flashlight is not your tactical priority and are accepting the likely localized discoloration.  It will Not negatively effect function under typical intermittent use.  It is the duty of the operator to monitor and rotate the flashlight if needed.  It is optimal to orient the flashlight providing the maximum material thickness toward the "High Gas" port in the event severe battlefield conditions warrant its use.
