I think FiveMega still has some Sprial mag bodies, which are bored for 9 GP2000 4/5A high-current batteries in a Mag2.33D body. Get AWR to build a Hotdriver switch kit to regulate this light (just need an allen wrench to swap out switches) and you'll have an awesome light, with an external charging jack. Hook up a Universal Smart Charger and you'll rock. Get a small-hole Litho123 heavy stipply reflector for huge flood beam or a Five Mega LOP reflector for throw and decent beam quality.
