Whats the laws regarding muzzle devices on the 14.5" barrels can i just pin this (myself) or do i also need my buddy to mig weld the pin in? OR can i just weld the shoulder of the MD the shoulder of the barrel so i can cut it off later and reuse the MD?
also wondering if i need to grind to bare metal if i need to weld? The MD will be a VG6 nitrided. I imaging the surface treatment will contaminate the weld?
TIA!
