Never used, owned briefly for photo posing then replaced, has some mild scuffs in places that will be hidden once mounted and the fitment between barrel and receiver is actually pretty decent; very little wobble compared to other 203s I've had.  Can be rail mounted if you can get the right E&C clamp, otherwise to barrel mount you'll need to get a front bracket (hence the low price).  Can't guarantee which brands this will fit on, you do of course need the correct barrel nut type and cut-out/diameter of outer barrel for proper military M4/M16 mounting.
