My brother actually got me interested in mounting a light on my long guns. He lives way out on 26 acres of property and it gets 'country dark'. Numerous times he's had to get up in the middle of the night to pop some critter (usually rabid) trying to get into the hen house. Photo of one of the more Jason-like critters is in post #2 of this link: Examples of why one should always be armed in the woods He mounts an SK68 that I gave him on his Mossberg 88 and it has been a big benefit to him. So that got me thinking about it as well. I mounted an SK98 on my Mossberg 500 that I like quite a bit. I build the SK98 myself using a Noctigon star soldered to a Qlite 8*7135 driver. To say that it's bright would be an understatement. That full moon you saw last night...yeah, that was me. Use a universal mount for the Mossberg. So I decided to put one on my 995TS trunk gun. I choose a Convoy S2+ which in my opinion is one of the finest 18650 lights on the market. This one has a 7135*3 driver so not only is it bright (probably about 500 lumens) but it will have close to 48 hours run time on low (25 lumens). I ordered a couple of mounts of a slightly different design so that I can mount both an SK68 and SK98 on my son's 995TS and my 4095TS. I'll let him choose which one. Both are modded and are exceptionally bright. They should mount nicely. In the SK68 I'll be using a Trustfire Flame 14500 li-ion battery. Both the SK98 and the Convoy S2+ use 18650 batteries (usually TF flame, Sanyo or Samsung). Toying around with the idea of mounting a laser on one of them to play around with to see how well I like it. But happy about the lighting system on each.
