Thing is...there is no standard for barrels...some are a hair to thick, some are a hair to thin.
Got a caliper to take readings?

It's an M4.
A caliper? I have the device to measure sizes of brake pads and rotors which could work. But ye when I put the two inner barrels side by side the stock one is longer by about a centimetre.
I'm about to try and swap them again. I'll post back with an update.
