Super product! - VISM ECO Prismatic 4X Scope w/Laser & NAV LED

I've had this sight system on my AR-15 SPR for over a year and Wow! Clear optics, reliable, easy to use and stays zeroed when removed and replaced. It literally has everything. Your iron sights are on top, laser sighting, etched glass reticle which illuminates for low light and is adjustable. Then is has a low level LED light in white or red that gives you just enough light to clear a room or navigate in a pinch without highlighting yourself. What else do you need. I'm still on the original set of batteries. In case you can't tell I love this system. It's a small package that gives you everything. At half the money of the military ACOG's and more features it's a no brainer to me!
