22 cal alignment check rod - Griffin Armament Suppressor Alignment Check Rod

22 cal alignment check rod does not work for 22lr only 556 .223 barrels. 223 vs 224 bullets It should be noted somewhere, but it's not so 60$ wasted. Also, if you have a 30 or 46 cal suppressor with 22 end cap, it's not really accurate. Idk if the internal baffles play a role, but I tried it with multiple AR uppers, and according to the pictures on Griffins' website, all would fail, but shoot fine.
