Available from SWS Germany. Used to be a good price but not so much now due to the exchange rate. Postage bumps it up a lot, helps if spreading the cost with other products. Last time I enquired, they had the old stock (the nicer glossy shroud), but might be different now. As said, a wanted thread might work, I have seen one change hands that way. The balance of the 4" is nice, but the fps is fairly poor compared to the 6" barrel.
