If you're not wanting to plop down upwards of 500 dollars or more for the latest EOTech with the elevated base in the front for going over the handguards, and if you're not concerned about compatibility with Night Vision, or with the latest reticle design, the 512 may just be the optic for you. It's better than just about anything else you'd find out there and while it isn't the fanciest EOTech available it covers all of the basics and it is more than adequate to get the job done. It will consistently put rounds on target, helping you to deliver accurate and precise fire.
Rugged, reliable, and affordable, that’s how one should describe the EOTech 512. With the EOTech 512 you get a lot in a small package. It's a lot of bang for your buck. You simply cannot go wrong with the EOTech 512, especially if you don't have a use for the additional features of the fancier and newer EOTechs. The 512 is classic EOTech, it's pretty much where it all began. If you're not looking for the bells and whistles then look no further, pick up an EOTech 512 and your AR-15 will thank you, well it would if it could.
