Unknown can do them, of course.
Preferred is using my reamers. I have been asked about working something out for you all to buy one offs.
The prior requests were for Tikka, and I still have a couple and am going to order some more 20” Tikka prefits. For your one off Defiance, I think it makes sense to let you guys use the reamers.
I will talk with them next week and post up what I decide.
