7.5 inch barrel not a 5 inch - CBC Industries 5.56 NATO AR-15 Barrel, 1/2x28, 1-5, Micro

The barrel is a 7.5 inch barrel not 5 inch since measurement should include the chamber (like how it is done for ATF barrel measurement) I only noticed because I was using this barrel for a pistol to SBR build so it's annoying to have to redo paperwork because the barrel is actually a 7.5 inch upon arrival. And the barrel index pin was a hair to big for either of the 2 barrel nuts I tried but fit after a few seconds of filing. But otherwise the barrel seems to shoot reliably and is fun to shoot
