These are Snowpeak made 16″ barrels with the same threading on the end as the short stock barrel. You can add a short carbon sleeve that can be used in conjunction with your end cap on the stock shroud, and it will slide inside the sleeve and lock the barrel and factory shroud down tight against the PP700sa frame making it nice and ridgid. Or you can choose the long carbon fiber sleeve and take off the factory shroud and use the end cap from your shroud to lock the barrel down against the frame and make it solid.
If you have your own plans for a shroud you can always just buy the bare barrel.

Supernice fellow to deal with. Barrel was perfect fit and swift delivery. Cracking bit of kit, please give us a shout if you can get any more in .20 or .22.
