Quality A2 bird cage that works as intended. Good value.

It's an A2 flash hider


Nothing wrong with this as far as quality and function. Only issue is that I am unable to to mount my griffin armament m4sdii silencer as it is slightly oversized. I'll keep looking.

Surprisingly well made


For how cheap it is, it’s actually very nicely machined and finished. It’s worth picking up a few unless they jack up the price. it does not come with a crush washer FYI.



wow no quality standards I got a threadless flashhider

Great Value!

Never spend much more on a flash hider. A2 is by far the best you can use to hide flash until you get into the $100+ mark. This product came in just like much more expensive A2s. Does the job.

Bought two, neither will thread on any barrel.

Basic A2 flash hider. Looks OK, but the threads on both of mine will not mate up to any 1/2x28 threaded barrel I have. I've tried several barrels and on all of them they will thread on about 2 turns and no further. Other flash hiders and thread protectors I have will thread on all of the same barrels without issue. I'll be looking to send these back for a refund.

Thank you for getting back to us on this and I see that we are getting this taken care of for you.
