I have no idea, but it is great while it last.

Regarding accuwedge and "O" rings or shims, I agree, these are bandaids not fixes.

Plenty... but it won't be fair. I happen to be a dealer. I have run into DD mk12 with some play to it.. still shooting moa. Double D demo gun that have seen over 16 k rounds.. sloppy but still moa. Even in hk417 and MWS, we have seen some play between the receivers, and they are still accurate. So 2 things, matching receivers from the same manufacturer do not guarantee anything, and a little looseness as you mentioned may not even be a big deal.
