sights have a huge window and field of view, have absolutely no parallax and may be used even when the window is dirty or even damaged! Unfortunately, life span on a single battery is effectively lower as laser requires more energy than LED. EOTech 551/552/553 In 2001, the EOTech 512 and 552 AA-powered sights were unveiled. They featured a long battery compartments as the batteries were placed per- pendicularly to the sight window. The 552 was a night vision compatible model with additional NV button which activated low-power mode and reti- cle was visible only in night vision devices. There was also a slightly more compact version of 552, named 551.A65/1 which was powered with 1.5V N-type battery (the battery compartment was shorter). 512 could be 3 meters submerged and 552 was 10 meter waterproof. All the sights fea- tured an integrated Picatinny rail mount with side screw. The 552 was the base for the 557 model with control buttons moved on the left side of the body, but it never became popular and was quickly discontinued. In 2006 US Special Operations Command official- ly adopted new EOTech 553.A65/1 HWS sights as SU-231/PEQ. It became a part of M4A1 SOPMOD Block I upgrade kit and replaced Aimpoint M68 (then Aimpoint CompM2) and Trijicon 1x24 Reflex sights. It was heavily inspired by 551 and 552, was NV-compatible but it was powered by more effec- tive and way more popular CR123A cells. The 553 had a quick-detachable mount with two ARMS le- vers instead of a single screw. EOTech 553 aka SU- 231/PEQ is 20-meter waterproof. HERE COMES THE NEW In 2009, EOTech debuted two brand new holograph- ic weapon sights, the XPS2 and night vision com- patible brother XPS3 with upgraded electronics and completely redesigned battery compartments. New sights were way shorter as single CR123A batteries ACCESSORIES
