I'm willing to accept the answer that I bought a cheap gun and should shut up and color. But the gist of it is that I got a new sccy cpx2 with the optic cut in the slide to play around with a red dot on a pistol on the cheap disassembled it and this is what I saw.

Sorry it's blurry and out of focus but that's about the best I could get it to look down the barrel without blinding the camera or having it focus on the feed ramps.

I've put zero rounds down it I did use an orange terry cloth to try and wipe it down so that's what looks like cheeto dust.

Just looking for some opinions on whether or not it would be worth sending back, or if I should just load it up and noodle around with it.

I don't intend to do anything with it but range toy and don't intend to feed it much more than 115 grain and 124 grain fmj.

You should look at the horizontal chatter grooves on some muzzleloaders. Many of these are very accurate. Although your photos are poor, the last one shows vertical lines. This should not make much of a difference IMO.
 
Yeah it kept trying to focus on the hood on the back of the barrel.

The lands look like the reamer chattered all the way down and the button didn't smooth it out, of course that's assuming that they button rifled it and didn't broach cut or something. I know that their big thing is that they cnc from bar stock.

I'll probably just shoot it as is I hate to send something back during all this, and I really can't get pictures that show what I can see.
 
I have seen barrels were it was clear the reamer picked up a chip and drug through the barrel resulting in the lands look like wash-boards and it still shot sub 1-MOA groups at 100 yards.

Shoot it first if it shoots good forget about the machining marks. If it shoots poorly then contact the manufacture and see what they will do for you.

That's about what it looks like the grooves are fine nice and brite but the lands look like washboards.

I've got a few boxes of blazer brass, a Winchester white box, and a box of leftovers (umc, aguila hollow points, and the last of the sig) I'll get out this week sometime and see what it'll do.

I won't sweat too much I am a terrible shot after all but I'll try and get some from a support and see how it goes.

I might touch base with them and see what they think but I really don't want to send anything out right now, with everything going on.

Pics offer no ability to diagnose, but no matter what, shoot it and see before anything further. It may be just fine. I have an H&R Handi barrel in 444 Marlin that looks like a failed shop class experiment. It shoots wonderfully. So, shoot first and then take better photos :p

Good luck!
 
I've seen Bear Creek Arsenal (cheap) Glock barrels, with rifling that looked like a plowed field, shoot as well as a Storm Lake or KKM barrel.

From what I've seen, it's the fit of the barrel to the slide that makes a significant difference in accuracy of a semi-auto pistol.
 
I had a 2.5'' barrel S&W 686-6 Plus with alot worse lands than that at the beginning of the rifling (and there was also some "torque" at the beginning of the rifling) and it was still very accurate.
I bet every SCCY barrel looks like the one you have.
 
It will probably do what it is designed to do. Shoot about a hundred or so rounds and see what, if anything, is wrong.

My old sp101 has terrible chatter marks in the barrel. Surprisingly I think it shoots fine. I had ordered the gun new. As soon as o got my hands on it, I hurried home and shot it.
I learned my lesson about inspection. Had I seen the tooling marks, I certainly would have rejected it.
 
I’m in the camp of the gun functioning as designed. It is a defensive pistol and should meet any accuracy standards out to the 7 or 10 yards that carry guns are built for. The good thing is that it’s a stationary issue in that it will be located and oriented the same for each shot so it should be consistent. It may shoot to a POI away from the sights, but with a slide mounted optic then you should be able to adjust for that.
 
Accurate or not THAT is extremely sloppy workmanship. Looks like a piloted chamber reamer with the pilot having very sharp corners. If someone had only taken a few seconds to radius the corners of that pilot it would not leave those marks. The pilot has also probably got lots of metal chips stuck in it. Sloppy.

I don't see much of anything in the supplied photographs.

BTW, here's what broach chatter marks look like:
