AOW's: legal in WA with approved Form 1 or Form 4
http://www.atg.wa.gov/opinion.aspx?section=archive&id=14312
An AOW is any firearm that doesn't fit the definition of "Pistol" "Rifle" "Shotgun" "Short Barreled Rifle" or "Shot Barreled Shotgun", "Destructive Device" or "Machine Gun" for this discussion simply put, a pistol is a rifled barrel firearm designed to be fired by one hand. If a VERTICAL foregrip is added it has now been designed to be fired with two hands and no longer fits the definition of a pistol. Note that Holsters that conceal a gun but still allow it to be fired are AOW's as well (think wallet holster with a hole for the trigger finger only hiding the gun inside)
SBR: only legal to FFL's who are a Special Occupational Taxpayer, LEO, or government approved entities and people who owned it before 1994
A SBR is a weapon that measures less than 16" from the front face of the muzzle with any permanently attached device on the end of it to the face of the closed bolt. Or a Rifle less than 26" overall even if it has a longer than 16" barrel. A folding stock weapon is measured with the stock extended for official measurement purposes.
AR Pistols are ok in WA but you can not put a shoulder stock on a weapon that does not measure more than 16" from the face of the muzzle or a permanently attached muzzle device (silver solder and blind pin welded in place are acceptable permanent attachments) to the face of the closed bolt.
Note that in washington state law that once a shoulder stock has been put on a receiver the weapon can only become "a weapon made from a rifle" from that point (RCW 9.41.010 (14) and (17) ) and is illegal in WA pursuant to 9.41.220
