Higoo® Tactical High Profile Dovetail Weaver Rail Adapter, 11mm to 20mm Picatinny Riser Mount

Product seems well made but you can’t actually see through it to use your iron sights. If this is your intention, don’t buy this. It is advertised as see through, which technically,it is, but it blocks the view of the rifle’s iron sights. Not happy with this purchase or the customer service. Update: I received a very unpleasant email from this seller. The service keeps improving. Second update; I received yet another unpleasant email from the seller! ??????

perfect fit
