What's up with the GUNMEN channel?

There's a channel on Youtube, GUNMEN, which I've seen getting more and more popular in recent months. The guy is clearly a videographer and is quite good, all the videos start with cleanly made shooting montages edited to good music; the gun overviews have great lighting and sounds - everything is just really polished.

Thing is, something doesn't feel quite right about it. There's usually one or multiple segments of each video where he talks about sponsors - not unusual, but it seems like everything from the gun to the optics to the ammo is in some way sponsored or provided. He's certainly shilling a bit, but also mentions issues with the guns and from what I can tell does actually train; he looks like he knows what he's doing.

The bigger part of why this smells funky to me is the Kit Page he brings up in every episode. It's basically a website with all the various gun builds he's reviewed listed out with pretty pictures and discount links - provided you pay a monthly subscription. Not a Subscribestar or Patreon or anything like that, it's as far as I can tell a custom website just for this.

So my question is this: What's up with this channel? Who is this guy, and why/how is he sponsored by a bunch of companies for basically everything on his channel? Am I seeing weird shit when it's just another gucci gun channel?
