I am hoping you guys could recommend an ar smith that will do some work for me. I have a grendel upper that started life as a gen 1 gdmr from Alexander arms. It has a funky contour and thread pitch. I want to get installed an adjustable gas block and handguard that I have, and get the threads recut so I can use the 30 cal muzzle devices. I am probably going to need to get the barrel contoured in front of the gas block. I could do some of the work myself but not the thread cutting and contouring so I was hoping to find a smith I can just ship the parts off to and have it built up.......
and recommendations?
