yeah, it replaces the flash hider, but it doesn't work on all ar's, i.e. some bushmasters' flash hider is permanently attached

Here in Aus if you get caught with an AR-15 without a proper catergory D licence (dealer licence) you face a loss of all your guns and licence and possible jail. It is so crap when you storm up a mob of pigs or goats and you can only use a bolt action.but that doesn't stop people from smugling them in so it is really pointless.

I got a Ar-15 for my 18th birthday its a sweet shooter.

I have one, a Daniel Defense m4 with magpul grip and a comp that i added after i took off my flsh hider.I use mine for hunting a little but mostly for personal protection because im in the process of going int olaw enforcement.I would never trust my life on a Bushmaster or a DPMS.ALfter you hold a good quality AR and take it down and check out all the stamping of the bolt carrier and stuff you would see the difference very quickly.Bushmaster arnt stamped nearly as good as a defense ar.I wouldnt hesitate to buy a bushy for hunting only tho!good luck and enjoy your new AR!
