| I want to put on a Troy low profile gas block on a Bushmaster carbine. After looking at the block i do not understand why the hole where the gas tube goes in is a thru hole and not a blind hole. Am I missing something? How is it going to cycle the gas back into the tube? Is there a plug that I need to get? Can someone please help? |
