Ok thanks, so I do need a special mount that goes over the handguard like that one? are there any that are cheaper that mount onto the carrying handle, or the rail in the case of an M4A3?

the EOTech is meant to mount directly to an A3 type mount, aka the M1913 Picatinny rail. if you have a fixed carry handle or just want to mount it above the carry handle, you'll have to get an adaptor made for such or the gooseneck mount as pictured above which will allow you to co-witness your optics and irons. check Brownells, ARFcom, etc. there are tons of them.
ETA: you can also replace your stock handguards with a 4 rail system and mount it to the top of the handguards.

Spend the money and replace your upper with a Rock River UTE2 upper. It's a thing of beauty and it allows a fixed rear sight for co-witnessing. Also the mounting to the receiver is rock solid. I've tried the Benny Coley carry handle mount and I wasn't impressed. It's very simular to the one above. Good luck.

You can mount the 512 directly on your standard flattop upper with a standard BUIS (for example, a Matech PADS) and the sights will co-witness with the Eotech dot...
No need for the RRA UTE2 unless you want the UTE2 for other reasons...
I don't mean anything negative here about the UTE2 either...
