Vintec, very very nice!
But it raises one question for me, if you have the hardware,knowledge etc why then are you getting a gun smith to do the rest? no disrespect to intendended to gunsmiths, but man you obviously got the skills !
buy the barrel, reamer etc do it youself, muzzlebreaks aint all that hard to make either form personal experience.
No doubt your going to tell me its one of your crazy american laws that joe blogs cant make/finish a firearm unless your a certifed smith operatering out of a certifed workshop,and certifed machines with certified certificates on the wall to say that your certified by the cheif certifyer to undertake this kind of work
Which after all that work I would completley understand.
Looking forward to seeing how it ends up.
best of luck
