My R700 5R in AICS Stage 2 is at PCR right now....getting the same knob installed along with the shroud mod, black cerakote, Timney trigger installed, and threads for a suppressor. Can't wait to get her back!
Brad and Keith Johns at PCR are great guys to deal with. I have never heard anything but positive comments about the quality of their work. That is why I shipped my rifle across the country for them to work on rather than try to find someone here in Florida.
I just hate having to wait to see the end result.....it will be a at least another 5-6 weeks before it is done.
