Great product - Vortex OPMOD SPARC II Red Dot Sight

I have only been able to shoot with it once but I made a two click adjustment and was able to stay with in the size of group that I wanted. My adjustments were made while shoulder firing the rifle so it's not perfect or exact but I am extremely happy with the product. It seems to be well built and hopefully will last a very long time. The thing I like most about the products from vortex is if you are building a more budget friendly build like I did but don't want to sacrifice quality, then the vortex optics are the way to go. Thanks!
