Hi there,
I have a amd65 with a us made barrel just over 16". Because the AMD65 has a shorter gastube and piston, the frontsight is way out there and if I put the muzzlebrake on its way way out there and looks rather hideous. I am thinking about moving the sight closer to the gasblock and then cutting the barrel and welding on the muzzle attachment to reach back to the non SBR 16".
Is there a way to do this without needing to invest in over 100$ worth of tools for a one time use? My barrel is .580 in diameter and to cut new threads I would need to get this down to .545.
My idea was... could I Instead cut and crown the barrell to the desired length, then hone out the muzzle device threads to .580 (maybe with a 37/64 drill), slide the muzzle device on and then pin and weld? Since it will be pinned and welded, is it absolutely necessary to cut threads?
