Looking at this picture I would agree. Beyond just talking about the gap there seems to be both radius and dimensional differences between the feed ramps in the extension and in the receiver. Could be edges and/or pointy-protrusions that could impact the case as it inserts... Now this is a bit grainy and only a photo and you will have a much better eyeball view but seems to be several dimensions of mismatch going on between the 2 pieces.
BCM purposely cuts their receivers a bit small to ensure a snug fit, they suggest you heat their recvr and then insert the barrel, let them cool then. If these guys did that too then that might be a good thing. OTOH if it just happened to be mfr variance, who knows if that's good or not.
