I've got a dozen or so on the shelf from the run I made when I started my 600OK project. It is based off of the Vias design is a good as any and better than most. If I remember correctly the threads are 7/8-14 but these could easily be opened to 1-14. I would use a 14 TPI over a 12 TPI. It's a more standard pitch.

Recoil is far too subjective to be making claims regarding effectiveness and there are too many factors outside the manufacturers control anyway. I won�t make any claims in that regard.

I'm in the process of making a larger brake for the 50BMG that will have 1-14 threads. OD will be 2.500" for the largest one and 2.050 for the smallest. I'll probably make a half dozen extra of these as well.

I usually only rough in the thru hole (.375) and do the final clearance once it's on the barrel. The smith will need to taper the back edge to blend into the barrel anyway and this insures concentricity. I know my threads are concentric within .0002 but I've got no control over the threads on the barrel. With someone who knows what they are doing there would be no problem but I've heard of more than a few guys putting on threads with an acorn die and a box wrench so I play it safe.

Any of these larger brakes could be modified to accept a .700 or .729 bullet with ease. Just bore out the hole with clearance (I like .020 per side).

I'm sure I could do an oversized AR50 brake for a 700 cal but I wouldn't be interested in doing it. There isn't enough of a demand for that to justify the programming, fixturing, set-up and testing that would be required.

Finally I don't know anything about carbon wrapped barrels so I can't help you there.

BTW- Thanks for the compliment Rob.

Thanks for the info Fritz!
