Can someone tell me what model this is?

Can someone tell me what model FLASH HIDER this is:




What are the pros and cons over a standard A2 flash hider?

Can a bayonet still be attached with this flash hider installed?

Thanks.

That's a quick-attach mount for an AAC suppressor. Pro's are, obviously, you can attach a suppressor quickly, and it's supposed to have pretty good flash suppression.
