Save your money - Wilson Combat Adjustable Lo-Profile Gas Block

Save your money and buy a different brand. The gas block does not restrict flow enough to adjust BCG cycle. With their adjustment screw screwed in all the way, too much gas gets through to make a meaningful adjustment. When I contacted WC about this issue, they told me to buy another gas block from another vendor. WC customer service is non-existent and they don't stand behind this product.
