A2. No muzzle device, it has a crowned muzzle. I have photos but I need to figuire out how to post them.
I am wanting to get a M-4 upper instead, that is why I am selling this one. If you have a Bushmaster or Rock River M-4 with a bolt and carrier, we can talk. I would prefer the mid length handgaurd if possible.
E-mail me at email@example.com for pics.
