512 eotech - EOTech HOLOgraphic Weapon Sight 510 ( 511 - M511 ) with Scopecoat Protective Cover

My intended purshase was out of stock and was replaced by a 512. This was done after notification by your company. The susequent 512 is more than acceptable and is presently mounted to my M4. It is my second 512, which is also mounted to another rifle. The second purchase should speak to my satisfaction with the product.
Pros: Large view port, ease of installation, and function and performance in all lighting conditions
Cons: Maybe weight, but everything must weigh something.
