One of a kind, unique and patented.  This front sight is way cool!!!!  The patented 2 piece design allows you to set your zero as you normally would, then rotate the the blade back into a positive clicked position selecting from either the big dot or the small dot exposure.  With a awesome 5/8 moa adjustability you can't go wrong.  Its a "Limited" thing, but a great addition to any rifle for the new and exciting "Tactical" USPSA division.  Available in 3 sizes:

-Mil-Spec .070

-Match .060

-Ultra Match .050

     and the blades are interchangeable providing even more flexibility.

We highly recommend the folks at Mounting Solutions Plus for this product.
