    M4 with 14" barrel and Muzzle Blast?

    I have been looking to buy my first AR, my son was coming into town and brought his M4 with a 14" barrel and a flash suppressor, the muzzle blast or noise from the M4 is 3 to 4 as much as my .223 bolt action rifle.

    My question is are all AR's this loud?

    I it barrel length or the flash suppressor?

    I don't think I want a AR if that much noise is normal, one reason is our range is close to some great neighbors and I don't want to subject them to the noise, and my ears ring tonight even with having my normal ear plugs during shooting today.

    I've shot a few ARs and haven't experienced a really loud report until I shot a 14.5" with a pinned/welded brake on it.I was flinching with every shot.This has me thinking of buying a full length rifle and forgetting about carbines all together.YMMV.tom.

    Was the flash hider a flash hider, or a muzzle brake?

    They are loud.

    Not awful. Awful is Mk18 and Colt Commando.

    A 20" barrel is much quieter.

    What muzzle device was on the "14 inch"? Muzzle brakes are bad ju-ju

    I've fired the M4 extensively, and own a 14.5 inch midlength I fire several times a month, and haven't really noticed it being excessively loud. I'm comparing to a couple 16 and 20 inch ARs, and the 20" M16. Never tried a brake, and I always wear one layer of ear protection, so ymmv. Was this under an overhang at a range, or was a brake used?

    You could always rock a sound suppressor!!!

    They ain't bad at all once you get used to 'em. Now an 11.5" upper with a Surefire brake in an enclosed indoor shooting lane.... WOWZA!!!

    I am sorry it is a flash suppressor, I did notice more noise while someone else shot and I was behind them, verses me shooting.

    True dat! My dumbass sat there and watched Belmont load his Mk12 upper with an Ops Inc brake on it, flip the safety onto "fire," and squeeze the trigger... all while my electronic earpro was sitting on top of my head.

    My right ear rang like a son of a bitch!
