Hey guys, legality question. I have an extended muzzle brake for 30" overall length when folded on my AK 74, must this brake be actually tack welded on and permanent? Or is the spring loaded retaining pin that holds the threaded device on sufficient? I assume the answer is that it must be permanent, thus welded. Thoughts?
And if I must permanently attach it, should it be brazed (low heat) or is a small tack from a mig welder advisable? I realize mig welds are messy, but I'm confident I could get a clean tack on the underside.
Thanks for reading.
