WTS: Used Surefire M-500 Tactical Light. This is the older model without the LED. I have the original box and the spare bulb. Excellent condition SOLD PF plus shipping. Paypal 3.3% more or US Postal Money Order. Please contact me if you have any questions. The first person that says "I'll take it" gets it. If you are not serious about buying, don't waste my time. I've had several folks say they wanted this, and then backed out.
Here it is mounted on my rifle.
