Questions & Answers
Is the 1/2×28 for 9mm? Expert Answer

The 1/2x28 KAK A2 Birdcage uses a 5.56/.223 bore. It is not compatible with 9mm. Unfortunately, we do not carry the 9mm 1/2x28 version of this flash hider.

Does this item come with a crush washer? Expert Answer

The KAK A2 Birdcage will not include a crush washer. I'd recommend the Luth-AR Crush Washer found using the following link:

no frills but does the job by Dan, Verified Owner, May 22, 2021

Good A2 Flash Hider by DMuss, Verified Owner, April 27, 2021
Good cheap muzzle device for any build. Fulfills it’s purpose. Threw it on my new 16in build, would have been cool if it came with a crush washer but it made me butt a pack so now I have extra so I’ll count that as a win. It’s nothing special, but it...

muzzle devices for 9/16" threads are hard to find. options are few. this fits and works fine. if you are going to build a 9mm ar15, I recommend you get the barrel thread 1/2". I can recommend this. also recommended for 9/16 is the midwest industries ...

I just wanted a low price birdcage that also serves as thread protection… I am guessing these are rejects idk … the slotted holes do not go all the way around…. Like they forgot to machine them out ….
