Everyone really has to give up on this "it looks like a silencer, I might get arrested" bit. Its not a silencer, or a suppressor. Its a hunk of metal. Some rifles have heavy barrels, that might make them 100000'th of a db quieter than a light profile barrel (though I doubt it, big deal if it does) some .22's are quieter than others, big deal. Whats on the end of this rifle is not designed to suppress the sound of it firing, thus its not a suppressor (I know a pop bottle isn't either, but if you put one on the end of the gun, its for the purpose of suppressing the sound, this is for looks). If we keep asking however, some anti's going to pick up on it, and decide its a good idea if they were banned. Heck, sound is the transmission of waves via the air, technically bedding a rifle stabilizes the barrel possibly making it quieter, who knows.
Just my 2cents.
