I've used Rainier Arms for years, they are my go to people for anything AR. I've recently used them to cut/crown/thread a Daniel Defense 16" barrel. I also had them pin a Vltor gas block. The turn around was about 10 days and the work was superb. Crown and threading were very nice and the cut was spot on.
Have no reservations about RainierArms gunsmithing.
