Frequently Asked Questions
Q: It seems like there would be a great deal of heat transfer to the light and mount. Is that a problem?
A: No, we spent nearly 2 years on structural, ergonomic, and thermographic testing evolving the product through incremental design improvements before making The Original PuP Light Mount available to the public. There are several engineering strategies used to mitigate the the build-up of heat. We minimized the contact areas on both the gas cylinder and the flashlight to create a maximal thermal break and allow for additional convection air cooling. In several areas we increased the surface area to aid in radiant heat exchange to air. This gave 2 benefits; reducing weight and decreasing thermal mass which would retain and transfer heat.
Q: You mention that, " after several magazines the flashlight tube can get warm to the touch." Should I be concerned about that?
A: No, we were able to operate the light with a bare hand after the 240 round strings but it was getting uncomfortable. If you are shooting that volume of sustained fire and are uncomfortable with the heat, we recommend any standard tactical glove. The advanced thermal mitigation design will cool the system quickly. Our military tactical advisors told us that a rapid 6 magazine test would be indicative of a worst case battlefield scenario. We coupled that with our previous testing that showed maximum heat build-up in the system at 1 second shot intervals to create a worst possible, worst case scenario. That became our benchmark.
Q: Why not just mount it on the side rail?
A: The rail mounted lights have 4 major drawbacks. They typically require a tape switch to be attached in a cobbled-up way to the vertical grip, usually double-stick tape or rubber bands. The wire connecting the tape-switch and the light has to be creatively routed to avoid getting readily hung up while moving. The profile of the rail mounted package is significantly wider. Rail mounted lights do light up the weapon more causing the operator to get blinded by their own light, and more importantly they cast a significant shadow to the opposite side of the rifle. In which your threat may be hiding. Relative to the rail mounted lighting systems the number of potential failure points on The Original PuP Light mounting system is significantly lower, fewer screws, no wires, no tape-switches, no double-stick tape, no zip-ties, or rubber bands.
Q: How did you determine the position for the mount?
A: The Original PuP Light Mount positions the light's activation button directly in the zone where the left thumb was "intended" to be by the designers for right handed shooters. It is also quite conveniently located when transition shooting as we tested this extensively also. So lefties aren't left out on this one either.
Q: Does The Original PuP Light Mount fit the new Lithgow EF88 / F90 Rifles?
A: Yes, It Does! We test fitted it at the Manticore Arms Bullpup shoot 2016 and it fit great.
