Test fit first...
by Browncoat -
I've purchased multiple AAC muzzle devices and haven't had any issues. This was a very rare instance and, I feel, more my fault than AAC's.
<br>Bought this for a new built, tried threading it on and it seemed to get too tight, too quickly. I removed it and tried an old Brakeout I had and it threaded up just fine, so the barrel threads were okay. Long story short, the threads were too shallow on the Blackout, ended up getting galled up on my barrel and had to cut it off with a grinder and a Dremel.
<br>Bought a 1/2 x 28 tap and die and chased the threads on the barrel. Most of the mess cleaned up okay and I installed the old Brakeout.
<br>Just a warning to others, who probably have more sense than me... If it binds/tightens up too soon, don't force it. Chase the threads with a tap or return it for another one.

As with any AAC product I own, the Blackout FH is rock solid kit and you could probably break rocks with it. While the Blackout doesn’t necessarily need to be timed, I used some left over shims from a AAC Brakeout 2.0 to get the slots to line up at 10:00, 2:00 and 6:00.
No Shims in the Package

Please Note: Purchased 2 and neither came with the Shims.<br>Great product other than without shims your will most likely have to purchase them separately to use.
pice and service
usually I can find items like this AAC flash hider cheaper on here than the factory and shipping is great, I live in Alaska and some places think that is a foreign country, Thanks again Primary Arms

I use aac sdn6, so little choice. No flash what so ever, but there in the infamous PING!

Really nice firm flash hider, solid functional and very aggressive.
As promised, and a quality product
I use a 51T for suppressor mounting and have found it an absolutely solid piece of equipment. I needed one for another rifle and found it in stock at Primary Arms at a price that was the most competitive of other leading sites that did not have inventory. The item shipped out with exceptional speed, and I received it in no time.The quality of the product matches the quality of service I've gotten from Primary Arms. Thanks to all.
FAST FAST FAST!
