>EOTech 553s Are In

Steven K. Ledin,

>Finally got some EOTech 553 sights in. The first things I noticed was the silver colored stainless steel windage and elevation screws and the two small throw-levers on the integral ARMS mount. The sight is made to be instantly attached to a 1913 picatinny rail. It can be removed and reinstalled with no more than a one minute loss of zero. The recoil lug under the sight is true 1913, and will not fit on Weaver style bases with the standard recoil slot of about .146. The recoil lug is about .196 and will simply not fit. The side-to-side differences also preclude a proper fit on Weaver style bases. There have already been fit problems with some Rock River Arms flattop receivers, probably tolerance issues with the manufactured size of the rail.
The new 553 uses CR123 batteries, and runs up to 1100 hours on a pair of them. The battery compartment is secured to the sight to prevent loss or a drop. The base is about 7mm higher because of the ARMS mount, and I prefer the slightly higher dot position over the front sight post. It allows for even more peripheral vision, which is why the EOTech sights are my favorite top quality sights in the first place in a non magnified optical device. Be sure to read much more complete information on our website.
