I have an A2 flash hider on an AR. When the flash hider is screwed all the way onto the barrel, the hider is crooked. When I say crooked, I mean is is almost upside down. The hider is straight as far as being lined up in order to fire a bullet. No problems there. Its just that the ports are upside down. Do I need a washer or anything between the barrel and flash hider? If so, what size?
