The question is how much weld is required to make a 2 3/16" flash suppresor and a 14.5" barrel legal?
I'm talking about tig welding.

Completely around the barrel, last I checked. It's easier/cheaper to drill a blind hole and pin it. :)

Yeah, spot welds are frowned on. When I was a kid you could go to a surplus store and buy a "dewatted" M3 Grease Gun that had its chamber welded shut and the barrel was spot welded to the receiver. Then you could go across the street to the scrap yard and buy brand new M3 barrels still in the wrappings. Take the whole thing home, put the receiver in a vise and apply a pipe wrench, break the spot welds and ..viola.........
Of course, having a FA wasn't such a big thing then..........

The four accepted methods for 'permanent attachment' of a muzzle device:

1) spot welds at the 4 cardinal points

2) continuous weld at least 50% of the circumference

3) high temperature silver solder

4) blind pinning
