I forgot but do we know if the DMR variant has a free-floating barrel? I remembered we talked about this last year but I can't find that comment.
It's not confirmed, but I think it is likely looking at the way the handguard joins to the receiver at the back compared to the standard QBZ-191, as well as the lack of any obvious joins at the front of the handguard and the barrel or gas block (which is present on the standard 191).
