Tac One body and barrel coverage.
Looking to add an air cooled machine gun shroud to a barrel on my Tac One project. I know the front of the body extends over the barrel for "some" distance, but how far?
Basically trying to decide the barrel length and shroud length needed for a good fit.
The lapco shrouds are sized based on the typical barrel length they are mated to:
8" inch shroud is actually 6 3/4"
12" shroud is actually 10 1/4"
14" shroud is actually 12 1/4"
18" shroud is actually 16 1/4"
I don't know the measurement but u could just screw a barrel in then make a mark on the barrel when it bottoms out. Pull the barrel out and measure
I would if I weren't traveling... always get these ideas while my own stuff is 1000's of miles away.

Now, what you need to know, is how the barrels are measured when they give you the length. Is a 10" barrel measured from the absolute back of the barrel, including the threads, or does it measure 10" from where the threads end?
