For the guy above who asked if this will work with 300 Blackout... only if you find a 300 Blackout barrel with a thread pitch of 1/2x28. Most 300 Blackout barrels have a thread pitch of 5/8x24, which is not compatible with this product, as it clearly states it is 1/2x28. Maybe I'm wrong, but I'm confused about why 5 separate people say a 1/2x28 thread pitch flash suppressor will work with a caliber where nearly all barrels are 5/8x24.

they also make 1/2 x 28 - 5/8 X 24 adapters

Will this work with 300 blackout

Hi John Yes it will work with any 5.56mm Caliber that is 1/2"x28 Threaded

The Blackout flash suppressor is the most efficient design available. It has been military tested and selected. The proprietary features eliminate muzzle flash, even on CQB-length barrels. The Blackout is inherently stronger and more impact resistant than four-prong designs, while not being subject to the rapid erosion of closed-ended units. A high-strength, corrosion-resistant aerospace alloy and ultra-hard SCARmor finish provide the highest level of durability.

It is the one that works with my device, it does have that ping sound when fired, or you work the action, but the product does what it’s intended to do.

Excellent AAC flash hider. I have it mounted to my AR-15 with standard 1/2 x 28 threads and it allows me to mount 7.62 caliber suppressor.

The 51T flash hider is another rock solid accessory. For me it allowed attachment of a suppressor and is offered at a great price by Bud's!

One of the best flash hider designs on the market, the AAC blackout line never disappoints. Great quality from AAC as always, when running both with and without a suppressor. 5 stars.
