I'm pretty sure CZ\DW still makes the barrels and shrouds for most models. Here is an email I received from Genny back in July:
The shroud only for the 744 in 10" is $219.00. This price is good for the shroud with front sight only. We do not have to laser it if you prefer us not to. Just let me know. Shipping is extra. Thank you for contacting Dan Wesson Firearms.
