Not what is pictured - Luth-AR AR-15 Adjustable Gas Block .750 ID

I liked that the add showed the +- on the side and seemed pretty regular otherwise. However it came in without any +- on the side. Instead the set screw is on the side, with adjusting from the front. Also the thickness of it as the side ramps from outside the barrel to outside the gas tube is a straight, flat surface in the photo where mine is curved in between the two. Think like hips on person I suppose. It all seems fine so far, just not what I was ordering. Hopefully it’s the same quality or better and not something cheaper in the same packaging. Bag was sealed, all hardware was there and number GB-750-A printed on the bag.
