Having Rusty from Form1suppressorforum machine for me an adapter for an “over the barrel” Suppressor mount for my STG 77. I just need to give him the measurement of how long the thread and spacer sections are on the barrel. If anyone has a barrel with the muzzle device off, can you take those measurements for me please? I’m waiting to take off my muzzle break when I get my Form 1 approved and adapter machined.

Thank you

FYI the the area you want a measurement on varies between barrel lengths. STG77 is a 20" barrel, but were all 20" barrels cut identically? Don't know.
