5 stars! cheap, simple, works. - Caldwell PAS Caldwell AR Receiver End Plate Sling Mount

I've used these on quite a few builds. Its nice how they wrap around and are truly ambidextrous. They can accept many types of fasteners which I prefer the mash hook single point slings made by kley zion. Also there are no sharp edges and it doesnt make contact with your hand. For some reason the optics planet app will only let me give 1 star.
