I’m about talking the BWE waiting list. I spoke with him already. I can only assume Richard supplier has been affected by COVID because he doesn’t have an ETA on blanks. I’m looking for an alternative source. I’ll even purchased used!
Why not just send a barrel out to get threaded for a 3 lug adapter?
I would get a 3 lug adapter from HK Parts that is threaded almost the entire length and do it like this:
only 'downside' is it will most likely not be timed so that you have a lug at 12 o'clock but who cares. If you are putting a suppressor on there it won't matter. You could probably pay someone a little extra to try to get it to be timed right at 12 o'clock but I wouldn't.
Going this route you can use a barrel that you know already runs 100% in your gun.
