I have a Surefire M900A with the white LEDs that I purchased earlier this year. It has been mounted on the gun for several months and been to the range twice. It looks brand new. It comes will all the factory accessories, manual and original box. Also includes the Surefire FM-17 opaque bezel cover. Here is a pic of the light mounted to my M4 without the FM-17.
Price is firm at $355 shipped. I accept paypal (+3%) and money orders. Questions to firstname.lastname@example.org. Thanks.
