I have for sale a brand new B-Square #18526 Nato see-thru scope mounting kit for AR-15's and M16's. This is a complete kit with a see-thru base (so you can use your iron sights) and heavy duty 1" rings. It is for mounting a scope to the A2 carry handle. This complete kit sells in Cabella's for approx. $50.00, I'm asking $25.00 shipped.
