The YHM HUB direct thread mount in 1/2×28 converts a HUB-compatible suppressor to direct thread for barrels with the most common 5.56 and rimfire thread (YHM part no. YHM-2189-28). To install it, remove the existing mount from the suppressor, thread this mount into the 1.375×24 HUB threads with a 3/4-inch open-end wrench, then thread the suppressor onto the barrel. Yankee Hill Machine machines it from heat-treated 17-4 PH stainless steel and finishes it in black oxide. It is only 0.3 inches long and weighs 1.7 ounces, so it adds almost nothing to the overall length. It is a clean way to dedicate a HUB can to a 1/2×28 host.
