I have been looking at getting a flat top ar for quite a while now and have been comparing Bushmaster, Armalite, and Colt. I have been focusing on the carbine length flat tops with target triggers. Recently I noticed that armalite offers their version with a flash hider while the others don't. What makes this armalite legal? Is there some sort of impact on precision with a flash hidder that Bushmaster and Colt know about and therefore do not provide their carbine length target rifles with flash hidders? Personnally, I think the armalites look pretty cool and I am kind of leaning towards them. How do they shoot?

Thanks,

Karl

It's not the device that effects accuracy
but what happens to the barrel as
it is put on.

Also that device is a muzzle brake.
