Great so far - Sightmark Wolverine 1x23 CSR 4 MOA Red Dot Sight

This CSR fits on my AR Pistol just perfect and I love the sleek, rounded design of it. The dot is crisp and easy to see even though I wear glasses. The red dot is very visible with both eyes open and I don't lose it when sweeping the firing field with my AR.
With the discount Optics Planet gave me, they have best prices I could find and I'll definitely be ordering from Optics Planet again.
