I see someone selling an M1A Bush rifle online, but with no pics.  Is it just an M1A with a Mossy Oak stock?

AFAIK, an M1A Bush rifle is an 18" bbl'd M1A.  It's basically the Scout Squad, without the forward scope mount.

It's a rifle used for bursting eardrums of friend and foe alike within a 50yd radius.

What OEF_VET said but I think the Bush rifle came with a neutered flash hider in the free states.

Yeah, they all came that way.  I have a pre-ban (not that it really means anything these days) that came like that.  Actually, you can't take the gas cylinder plug out to clean the gas system if you don't shave off the lug.  I guess that's why they came that way.

True for the most part.  From page 128 of my book M14 Rifle History and Development:

"Commercial Stabilizer – Springfield Armory, Inc. very briefly made its own version of a muzzle stabilizer which included a bayonet lug for its folding stock M1A-A1 Bush rifle prior to the 1994 ban.  The front portion of the Springfield Armory, Inc. muzzle stabilizer has a short bird cage style flash hider.  It threads on to the rear portion but is held in place by a single SAE 10-32 thread setscrew on the bottom.  Removing the flash hider reduces the length of the rifle by 2.75 ”.  The rear portion of the muzzle stabilizer consists of the front sight base, bayonet lug, and a cylindrical section perforated with gas venting holes.  It is marked Muzzle Stabilizer Springfield Armory on the bottom.  The outside diameter is 0.6 ” for the entire length of the stabilizer."
