Can someone please tell me- muzzle brake or flash hider?

[afajvan]

Can someone settle an issue.
I am looking to buy a Bushmaster from a guy in ME, through a FFL.
I know the bayonet lug has to be removed, and it has a fixed stock, so no pinning involved.

looks like an A2 flash hider.

Ditto.

Looks like an A2 but could also be a JoJo's brake.

It is whatever you want it to be... . A friend of mine (lives in MA) recently purchased a Stag AR-15 from a local dealer. It had what appeared to be a "flash suppressor". My friend asked: "Is this a flash suppressor?" The dealer replied (with a big smile): "No, it is a muzzle break." Choose the correct answer or the "suppressor police" may be knocking on your door.

But seriously now...THIS >

Yikes:

"Birdcage Flash Hider Choke Suppressor Muzzle Brake Compensator"

The only missing word was "thingy."

Looks like a flash suppressor. You can typically tell by the fact that the "mouth" of the muzzle device is open. This open design assists in flash suppression. On the flip side, a closed design directs gasses out of the ports of the muzzle device--thereby reducing muzzle climb or what have you. I'm certainly no expert though.

Example of a muzzle brake. Notice that the mouth is "closed".

Flash hider. A Muzzle Brake or Comp would be "closed" at the front with a hole just big enough for the bullet to pass through.


Edit to Add: "Fred" beat me to it. +1!

definitively flashider.
aside from open mouth design, another giveaway is long slits that are all around. brake would have only on the sides and top.
