Great optic! i only have one issue. - Hunt World USA Saturn 4x32mm Tactical Rifle Scope, 32mm Tube, Second Focal Plane

Having researched the ACOG and the Saturn regarding eye relief, I have found them to be relatively equal with Saturn giving just a little bit more eye relief at 2 inches. With that said, I would love an optic in this class that gave a 3 to 4 inch eye relief with a larger opening at the rear of the sight. Regardless of that pipe dream, this is an excellent product! Cheaper than an ACOG and well worth it. I mean, they offer a lifetime warranty as well! I have two of them mounted on AR15 platforms. I very much recommend this product!
