how bad or hard is it to attach jb weld to a threaded prebn barrel to attach a muzzle break to make it postban?
JB weld is NOT an BATF approved method of attachment. NO 'chemical' means are.
The only legal methods to attach a muzzle device on a threaded barrel (for a pre-ban weapon) are:
- 4 equidistant tack welds
- High temperture (1100 deg) silver solder
- weld for at least half the circumferance
or (and this is the most popular)
- pin the muzzle device with a blind pin - then weld over the pin on the muzzle device.
