It does look suspicious, the ano looks different and the engraving/lettering looks off as well.
Have you checked the driver board?

If you still have the original packaging , look at it very closely for misspellings, unusual phrases. uneven printing. try to compare the package to a known Nitecore package if you can locate one. There should be instructions and maybe a warranty card included
Nitecore does a pretty good job with packaging.
If your light arrived in a plain (white ) box than for sure its a knock off .
@ sp5it: when I looked at the video I notice something. On my flashlight there is only written MT10A on the side compared to the one the video shows. So I googled MT10A images and I can’t find anything that looks like mine, all images I found have more text and that bin symbol.
All images of MT10A on the net has this on the side:
Mine has only this:
@Nicolaas: no, I don’t have any technical knowledge but I will compare it later as I’ve got to get ready to attend easter dinner.
@Paul321: I will compare it with my Nitecore EC21 packaging later on, gotta get ready for easter dinner soon.
I know it looks different, that’s why I suggested it is knockoff.
Post a picture of driver board.

Oh man , I had 3 pieces of this light in my hand , before I gifted them , and NONE was looking like yours !
The color is like it was baked in a oven , the knurling looks like a fade one , the printing is fake...,sorry to say , but "spi5it" seems to be right , it's a fake !!!
It could have been a batch with different printing. The charger of my TM26GT was slightly different than what all the pictures on the internet showed. I contacted Nitecore, and they verified my light was authentic. So I’d contact Nitecore if I were you to find out whether it’s authentic or not.
I have to agree, that isn’t a true Nitecore light…. this company makes an excellent product and the chance you’d get a clip that didn’t fit, new in box, is just like totally nil. And that light itself, yes, fake. Nitecore is a class act, that light is not.
Banggood may have taken a return and got scammed, may be completely unaware of it and think it is YOU trying to scam them. I honestly don’t believe Banggood would send that out as a real Nitecore intentionally.
Also pretty positive Nitecore uses Type III Hardcoat Anodization, if you bake it you won’t get bronze but an olive drab green sort of color. The bronze when baked is typically from Type II. And yes, that light does look baked…
I have to agree too, that is definitely not a Nitecore product you received. No way.

Ask them to look at this topic and comment to BG.
Still can’t believe, that BG intentionally sells fake Nitecore flashlights. But checking the different knurling and not that fine machining, I’m in doubts now…
I took a look at what I’m thinking is the Nitecore site flashlight.nitecore.com and there is one picture in the MT10A section that has a longer clip like yours. It’s the one where the flashlight is sitting on a rock. That flashlight has different lettering than yours. Maybe Nitecore recently switched manufacturers? Back when they were having problems with counterfeit chargers they had a site where you could enter the serial number (or was it the number in the hologram on the outside of the package?) and it would tell you if the charger was legit.
Okay I’m in a rush now, really have to go to attend the dinner party but I can’t wait about this so I took quick picture of the driver.
I can’t really tell the differences but the printlane (is that how it’s called?) on mine is bit vague. What do you guys think?
I found this picture from https://m4dm4x.com/review-nitecore-mt10a:

I think if they’re going to all the trouble to make a fake driver board that matches so well, then it’s probably a pretty good fake overall! 
It doesn’t look exactly the same, but it is very close? Look at the machining marks around the nudge in the ring, even they match up?
It’s Sysmax I don’t trust. I bought a factory sealed D2 charger with the authenticity sticker that checked out correct. Inside the box was a plastic battery case that said “Xtar” on it. I think these companies who do machining, driver boards, packaging, etc… are intermingled quite a bit. Probably not hard to buy a few hundred nitecore driver boards from the electronics company who made them. Especially if Nitecore didn’t claim all that were made, and the company wanted to dump them.
I’d bet the hosts were Nitecore rejects, and someone assembled them to dump off on the gray market. Who better to dump them off to than Banggood, Gearbest, & Fastech. Nitecore doesn’t recognize BG, GB, or FT as authorized sellers anyway, and will not warrant if purchased from those sellers.
RobertB - That looks like Slim Pickins’ from Doctor StrangeLove
It is, lol… Dr. Strangelove is one of my favorite movies, along with Young Frankinstein.
The clip looks like my clip that comes with the EC11. This one as far as I know is authentic. Came from Longhorntactical, a US based seller.

The lighting makes the color of your first pic look off (brownish). I noticed the black lanyard string also looks sort of brownish.
Me taking a close look at mine, the machining looks spot on, at least the head.

The bezel doesn’t come polished, I gave it the Caustic soda treatment and polished. I just had to add some bling to the light. 
Same here -
What Hump?
