SureFire 623LMG LED WeaponLight for Mossberg 500/590

New, open box. Discontinued by Surefire and extremely rare to find!
I bought this when I couldn't find a DSF590 but recently got lucky and found one. I have never mounted this but there is a deep scratch on the top of the bezel.
Light can be upgraded to the LM2-B for about $200 which will take this from 200 lumens to 1000 lumens.

$490 picked up anywhere between Newmarket and Uxbridge OR shipped at buyers expense.
