[QUOTE=Canonshooter;2419577]I'm running a Magpul offset BUIS set now so replacing the front sight wasn't in the cards.


- this light can run on high-capacity/high draw Li-ion rechargeable batteries (the X300, TRL-1, etc. can only use CR123 primaries)

I've got several flashlights that use the 18650 battery you are referring to. Two of my WML's use both 18650 and CR123's. The 123's are more convenient, but the 18650 is hard to beat as far as the lumens it can power and the battery life.

Only drawback is quality 18650's have a higher upfront cost than their little brother, the 16340, also known as the CR123. I say upfront cost becuSe most 18650's are rechargeables. I picked up a NiteCore charger that handles the 18650 and other batteries, and it works like a champ.

PowerTac 18650s

Gene sells good 18650's and if you want an additional resource, check out PowerTAC.
