I have added a Navy k-507... And maybe Navy's qc has gone up....
When I first bought my SRM 710s, I ordered the Navy K-622 (Al Mar Sere 2000 Homage) with em, and I absolutely HATED the thing. Ended up just throwing it away. :barf: It was an earlier model, with the solid clip, but the fit and finish was among the worst Ive seen - no, not that bad - not as bad as Emersons, but close.
The liner lock was so stiff, and sharp where you put your thumb to disengage it. The G-10 felt official, but the liners and the scales didnt line up well. The knife was dull out of the box, and just felt cheap in hand.
I was impressed with the SanRenMu 710s though - but recently have had some issues with the action - after two or three years, but not much use.
After exhausting the blade funds on a more expensive and well known American Brand, I still needed to feed that urge, so I splurged on a few more of these offerings from China. I ordered the SRM M4-735 (Hinderer XM-18 Homage), and two Navy K-507s (Sebenza with one G-10 side Homages), in hopes that I either got a lemon the first time I tried Navy, or their Q.C. has gone up, like you mentioned.
As far as the Chinese offerings go - do we really know who came first? The chicken or the egg? We know SRM does OEM for a handful of established domestic brand names - and we know that having X brand stamped on the blade makes the EXACT SAME knife worth four times more than the "REAL THING.
If the Chinese Spydercos and Benchmades, and CRKTs are actually re-branded SanRenMu knives, then Id rather have the REAL THING anyway, and save the forty dollars or so that whatever MIDDLE MAN company was trying to earn from me. It really is like skipping the middle man step, and buying wholesale.
To me, since theyre made in the SanRenMu factory - the Re-Branded versions are the FAKES!

Posing as something theyre really not.
I believe the prices we can acquire the SRM knives are very close to the big name companies cost, and the prices we pay for that NAME are really the three to four hundred percent mark-up - for a RE-BRANDED imposter - pretending to be MORE U.S.A. than the SRM, while not really.
Just like a Red Bull is three dollars here, and 25¢ there. Just like sneakers that costs hundreds here (manufactured there) cost $30 there. The inflation is HUGE - but when you get it from the source (China), you are not blinded by the trick of pretending to be more USA than it really is.
Of course, Im talking about REAL products, not blatant copies, where they actually put the makers mark on the tang - thats a completely different story.
So, if I was EVER going to buy a Chinese Byrd, Spyderco, Benchmade, SOG, CRKT, Buck, Kershaw, etc... I would personally prefer to save that 300 - 400 percent inflation, all while getting the REAL THING, straight from the source - NOT re-branded, false pride.
SanRenMu - I bet most people who boycott them, actually have a couple in their collections, that are actually re-branded SRMs without their consent or knowledge
SanRenMu - Just like GIANT Bicycles (China) makes a billion OEM bikes for tons of other brands - just re-branded.
Sometimes it feels good to save money - while getting the ORIGINAL version, and saving that extra forty bucks, instead of giving it to a company that is buying the SanRenMu knives for you, because youve got something against knowing whats really going on.
