Re: rem 700 barrel threading?
Though I've never used him (yet), it's apparent that Hooper does great work. Plus, turnaround time is always something to be considered.
I have used Tornado Technologies exclusively and have always been very happy with their work. I sent a Rem 700 for muzzle work and a Glock AA conversion kit to be threaded a couple weeks ago. They had it done and on its way back within a week. Plus, Mike from TT called to go over some details before starting to make sure he had the best results.
TT seemed to have some trouble the past year with turnaround due to their overwhelming workload, but it seems they are back on track now.
