I don’t know how to describe what it is but the M1 Abrams has it,

I think it’s something to do with releasing pressure so the gun doesn’t explode when it fires, thanks in advance :D

I believe it's called a bore evacuator. It's used to get the toxic gases out of the gun so it doesn't go back into the tank itself and kill the crew.
@Maxwell1 lol
Makes sure you don’t get that smok in ur turret cabin. Also depends on the gun your using. Mostly seen with guns above 75mm
@Aarons123 Ohh
@SoulWarden as Gestour said, it stops poisonous gasses from entering the tank after the gun is fired
Fascinating!
@Gestour
A muffler?
@Gestour cool
