I am in the process of getting an upper together.

I currently have a Krieger bbl that my brother has machined for me. I have yet to set the gas block or drill the gas port or cut muzzle threads.

I know I want to put the gas port in the pistol position (like it ought to be). I am kinda up in the air over how to set up the upper for adjustable gas. I have looked at the JP adj. block, thought of making my VOLTAR GB into an adjustable system .. and then I saw the Fulton Armory adjustable gas tube. On Fulton's site they only list a rifle and carbine tube .. do they make an adjustable pistol tube? If not how hard would it be to make my tube into an adjustable system?

Currently the bbl is 14"? or so. I have plans to install this onto an A3 upper with my LaRue 7.0 railed handguard and am thinking I want to cut the barrel back to maybe 1 or 1.5" sticking out past the handguard. Any concerns I should have with this set-up?

ETA: I currently have an SAS 30 cal muzzle break mount silencer waiting on a F4 that will be used with this upper!
