AAC Blackout FS

AR/M4 AR Technical Discussion
1

I recently got one of AAC’s new Blackout non-sound supressor FS’s to try out. I put it on my 16" Operator build. Finish and design appear excellent just at first look. Unfortunately, I have not been able to actually get to the range to try it yet, so I cant give any live fire data/impressions. I hope to do that very soon. In the mean time, I thought I’d toss up a few pics. If it works as well as it looks, I’ll be picking up a few more of these. Sorry for the crappy pic quality, I was in a hurry when I took these.

good guys who make good stuff, have you tuned some stuff with it yet lol

3

Despite the ring, the do work very well for flash suppression.

4

The ring is very distinct. And now for the worthless trivia of the day…the Blackout vibrates at an equivalent of 32 MPH, as confirmed by radar.

5

I keep meaning to get one of those for one of my SBRs. The cheap bastard in me keeps waiting for them to show up at Brownells so I can pay $10 less (hopefully). :stuck_out_tongue:

6

Mine even rings when firing with the M4-2000 mounted.

I like the ring its cool, I love to flick them lol. Its a very well designed flash suppresor. The boys and girls at AAC make top notch stuff and are top notch people. Rob you got a loaner KAC SR-15 right, just yell at Trey to try and get you a hook up on one.

Is there any benefit in trying to time it with a washer like the A2 flash suppressor? Or is that unnecessary for this device?

9

The Blackout is like a Vortex in that regards, and a crush washer is not needed.

10

If you want a “closed bottom” you can time it so that there is a prong at the bottom, otherwise there is no reason.

11

So in hijacking the thread if I wanted to time a Blackout would I use a peel washer or a crush washer?

12

Is it self-tightening like the Vortex is?

I could be way off…but my guess would be that whatever self-tightening the Vortex is doing would be from the twist it has to it.

14

Yeah that’s what I read.

15

is the AAC fh in the above pics shorter than a Vortex?

16

The AAC non-mount FH like above measures 2.125 inches and the Vortex G6measures 2.265 inches. Thats .140 thousands of an inch differance . G&R Tactical has the AAC in stock .

17

I’ve gotta stop viewing these review threads…

order placed :smiley:

18

The standard AAC Blackout FS is not indexed and is not self tightening. The FS come with a small container of Rocksett for securing it in place and the instructions specifically mention not to use any type of washers.

Sorry if this is off topic…

I am looking at getting the AAC Blackout for an LMT 14.5" upper. From searching the forums here it looks like pinning/welding will bring it to the required 16" legal length.

Are there any gunsmiths in the Northern Virginia area that you guys recommend to have it installed?

Thanks in advance.

1st post!!

It’s not going to be earth shattering. I’ve stood right above/next to my buddy’s 16" AR with A2 flash hider when he was firing XM193 in low light and you really had to watch to see the flash.
