My M1A scout, .308 isn't a huge thumper compared to what some have posted but the factory muzzle brake on it makes it louder than a M240 machine gun, my buddy I deployed with shot the 240 for 4 years and I told him "you're gonna want ear plugs man" he was like "nah I'll be fine"... Took one shot and looked like he got hit in the face with a brick
