The battery life is the same. The only differences are as you said, the shape of the front and the buttons on the side. I bought the 512 to save a little money but wish that I got the 517 because I am now planning on adding a magnifier.

517 sits, I think, 7mm higher and is set up for 1/3 co-witness with BUIS. 517 is clearly better choice as of now.

It seems having the irons centered would be better... The whole "eye wants to center things" everyone preaches about aperture sights would come into play here, right? |

You don't want 1/2 your view through the finder blocked by iron sights. Having the top 2/3 clear helps you see targets and get them in the fiield of the optial sight.

Is there a way to get a raised base for 1/3 co-witness with an Eotech 552?
I know the 557 has had some major problems... So it is out of the question. An Eotech 552 is similar, just without the 7mm riser. I kind of want to keep my night vision options open. |

The 517 is curved and raised to fit over standard handguards without a mount.
If you want a lower 1/3 co-witness with a 512/552/etc, you can buy a mount like the one from LaRue. This also gives you the QD option which I think is nice for optics. |

I use a Troy rear BUIS and a fixed FSB, and with the Trpy folded down, I don;t even notice the front sight. ETA: I have a 512 and have not experienced a battery drain issues. |

Does the LaRue mount allow you to have it mounted partially over the handguards? Is there a specific item number or name for this mount? I know LaRue makes a lot of stuff. |
