EOTech 552 & 512 What's the difference

[Ricky-Ray]

Title pretty much say's it all. I've been looking over the description and for the life of me I can't seem to find what's the difference between the 512 or 552 EOTech's.

552 - http://www.uscav.com/productinfo.asp...6211&tabid=548

512 - http://www.uscav.com/productinfo.asp...6140&tabid=548

Any help would be appreciated on what's the difference.

Thanks.
