I have a wilcox nightstalker sosmart vis laser module, universal picatiny rail mount, and pressure tape switch. It is in perfect condition. These units are very rare and are well saught after pieces due to little numbers. All the blink rates work and the led screen still works as well. $750 for the whole system, shipped to your door. Some info and pics of the unit are available at www.mark23.com and www.specwargear.com. look under the lights and lasers sections at each of the website.
Please contact me at email@example.com if you are interested.
thanks for your interest,
