Best EOTech for AR15?
 

I'm looking into getting an EOTech for my AR and I'm not sure which is the best one to get (only ever used ACOGs and Leupolds). I was originally planning on getting the 553, but have also been thinking about the 557. I plan on using this on my next deployment also. Any advice or help is much appreciated. BTW, does anyone know of a good store to get an EOTech at in the DC area, I'm at Walter Reed and can't seem to find anything locally. Thanks everyone.
