Crossfire ii 1-4 - Vortex Crossfire II 1-4x24mm Rifle Scope, 30mm Tube, Second Focal Plane

I purchased this to replace an Eotech EXPS3-4 with magnifier for a Sig 516. This is a very nice scope for the price. Works well for my old eye sight. I am Retired Army and have quite a bit of experience with the M16 platform rifle. On the 1 setting the eye relief makes it easy to find the target when using a good cheek weld to the gun. I prefer the reticle in the Vortex Strike Eagle to this dot, but the dot works pretty good also. With the lifetime warranty and Optics planet prices you can't go wrong with this scope.
