EoTech 552A651 Weapon Sight

This is by far the best Holographic Weapon Sight (HWS) I have ever owned. It has been field tested by our military and has a zero tolerance to failure. Using a pair of standard size AA, it is slightly longer than the other models such as the 555 (which uses the popular CR123). I have placed over 500 9mm rounds and 300 40SW rounds with the 552 sight and it is dead on. If you are serious about your gear then this is the best HWS you can buy for the price.

Standardized by the DEA, ATF, and FBI SWAT, the Model 552 is by far the most popular HWS model. This NV compatible, AA battery model is the sight of choice by military units like Stryker Brigade, 10th Mountain, and 3rd Infantry. It is battle proven to withstand the abuse that any harsh environment, high powered weapon platform, or military mission can dish out.
