The Model 512 holographic weapon sight was developed after EOTECH’s acquisition by L3. With improved durability, electronics efficiency, and a reticle designed for quick target acquisition, the 512 is perfect for home defense or even hog hunting. If a duty-ready optic is what you are looking for, the 552 was designed specifically with the Marines in mind. This model is fully night vision compatible and can be purchased with the XR308 reticle designed for full auto .308 Winchester use on the M240. Combined with the G33 magnifier, the 512 or 558 holographic sights can reach out and hitting targets at medium to long range. Replacement battery caps and repair kits are also available for both the 558 and 512. Since these models are older, they are bit bulkier than newer holographic sights. For the latest holographic optics technology, consider shopping the XPS and EXPS lines.
