The EOTech Model 516 was specifically developed for law enforcement use.  This extended run-time sight operates on the same CR123 lithium batteries commonly used by all other leading makers of law enforcement gear.  It features the standard EOTech ring/dot reticle with 20 brightness settings to allow for changing weather conditions and surroundings.  Extremely reliable and built to last, this sight it perfect for forced entry LE situations as well as mid to longer-range shooting, when partnered with the EOTech magnifier.

I have an EOTech 516 on my JT  |  January 05, 2015
I have an EOTech 516 on my Sig Sauer 516. 516 is a pretty lucky number.

I've had my 516 as my primary sight on my Stag ARMS Mdl-1, for the past 5 years. I love it and can't live without it. I have a magnifier, which really extends my range way past 100yds. I was showing off one day, while checking different sighting devices. I went through a scope, irons, BUS, and the 516. I'd shoot a few on one target, change sights, shoot again. Once I had gone through several devices, I put the 516 and mag back on, and told the guys that anyone could bullseye with this set-up. Two volunteers stepped up, from the a bench, with a bi-pod, using the 516 and magnifier. After each shooter took two shots. The three of us went down to check the target. There were four pairs of two's, all in the nine, ten and X rings, each pair had about a 1/4-1 inch spread. Took it apart, put back together and held perfect zero for me and three total strangers @ 100yds! Granted I have a really good gun, but still you couldn't have planned a commercial as good as that! They were impressed. I am still always impressed with it! I still have the target. Durable, rugged, tough and easy to install and use. Great reticle and view. Takes a little time to become proficient with it, then it's like they advertise "just point and click!'. Well built. Batteries last for ever. Remounts to the 1" spec every time! It's been rained and snowed on, baked in 100+ heat and frozen in sub-minus zero days. It's been dropped several times. I've shot competitions with it. If you have an AR15, this is the sight! It's one of my "Best Buys". 516's RULE!
