Umm..no.

Even out of a 7.5" barrel the 5.56 is not going to be subsonic, so I don't know how any of this is relevant.
Being loud isn't always a negative, in fact its the main reason I built mine. Pure, unadulterated awesomeness.I don't own one, but the only negatives I've heard are you obviously are going to lose a fair amount of power with such a short barrel and that they are incredibly loud.
None. 10.5" is typically the shortest you'd want to go on a true battle rifle. I've heard of quite a few SWAT guys running 7.5", but they're only shooting across rooms, so they're not as hindered by the short barrel as an Army Ranger would be.Since I'm not an AR person (yet), what exactly is the tactical or strategic advantage of such a short AR? I can understand 14.5" or even 11" for CQB scenarios or guns that are normally stored in vehicles, but I just can't wrap my head around why anyone would need/want to go any shorter than that other than just because they can.
Your logic seems absurd to me. Have you priced MP5's lately? Nobody runs a can on a 7.5" barrel, the massive pressure coming out the barrel can damage the baffles.That just seems absurd to me though. At that point, why not just go with an MP5, particularly when you're talking about running a can? This makes more sense to me seeing as both will be sub sonic anyway and the 9mm will carry more energy due to it's heavier bullet.

When I put my can on my 16" AR, its as quiet as a .22. I've never ran subsonic through it.Either way it supresses. I'm sure it is far from quiet using standard ammo. I'll leave someone that has one to more fully answer that. I know at least a couple of people on here have them. I think I read a thread on it in the NFA section.
RobC posted some pics of his new can after a few hundred rounds on a 10.5" AR. It wasn't pretty.
