uhhh what?
It's on multiple pages of the NFA handbook on the BATF website, but I cut and pasted this off of page 5:
"The ATF procedure for measuring barrel length is to measure from the closed bolt (or breech-face) to
the furthermost end of the barrel or permanently attached muzzle device. Permanent methods of
attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100°F) silver
soldering, or blind pinning with the pin head welded over. Barrels are measured by inserting a dowel rod
into the barrel until the rod stops against the bolt or breech-face. The rod is then marked at the
furthermost end of the barrel or permanently attached muzzle device, withdrawn from the barrel, and
measured."
Full fusion gas or electric steel-seam welding = TIG, MIG, etc...
High temp silver solder (1100 degrees) = silver brazing.
Hope this helps.
I never realized that's how they measured. Not trying to hijack your thread, but I guess under that method of measurement, a revolver style rifle would include the length of the cylinder in the barrel.
What are you pinning to what?
Will it be a suppressor mount? If so, make darn sure everything is concentric first.
Good point, don't want the end of the can going down range with the bean
Can you do mine?I can do it.Give me a pm about it.
I trust Jonathan at Reulet Gunsmith a excellent gunsmith CovingtonAnyone know of a gunsmith that can pin and weld a flash hider in the NOLA area?
Thanks!
