I have no experience with sub-carbine length gas systems, but that certainly won't work. What's the barrel?
What barrel is this?
Pistol length gas?
Black River Tactical

BRT EZTUNE Preset Gas Tubes - PISTOL, CAR, MID, RIFLE
BRT Bolt Carrier Groups M4A1, M16 CHROME
BRT Covert Comps 5.56, 6X, 7.62
i got the upper from a friend and was told it is a 7.5 inch barrel and the gas tube is 7 inches.
Not sure of barrel brand or length but its a 7 inch pistol tube but its supposed to be 7.5
Gents I removed the barrel to find that it's an 8 inch barrel but now I'm not sure what length tube I need.
The 8" barrel will use a pistol-length tube which is typically close to 4.5".
