Try to get another photo if you can.
A bad chamber cut looks like this and marks the brass accordingly when fired. That shit came from a manufacturer of a prefit.

It’s supposedly brand new.oh so sorry signs of ed at such an early age it's terrible . but fear not you can get it fixed but it will be painful .
No if you hold the barrel up to the light you can see the marks without the aid of a bore scope.Looks great, maybe a little fuzzy ?![]()
So far it has fed ok. The gunsmith that I took it to said it was way too rough. He showed me a pic of some cheap AK chambers he had and mine was way rougher.Does it feed well?
If you get a chamber too smooth you lose grip on the brass and can get false pressure signs. A cross hatch finish like on piston cylinder walls is about ideal.
If it feeds without sticking it’s fine. If brass sticks while trying to eject, you can deburr with a dowel rod and Emory cloth.
Does Desert Tech chamber their own or do they outsource it?Desert Tech
No idea.Does Desert Tech chamber their own or do they outsource it?
The brass does have markings similar but not as severe as @Cberndt ’sI added to my post when you quoted me. Check it out.
You know that cylinder crosshatching is used to hold oil for lubrication and guiding piston ring rotation right?Does it feed well?

Does it have potential to become a problem later on?looks like a bit of reamer chatter/vibration when the chamber was cut. Reamers will chatter/vibrate for a number of reasons, creating a washboard finish in the wall of the chamber.
The manufacturer has been contacted and I’m awaiting a response.You know that cylinder crosshatching is used to hold oil for lubrication and guiding piston ring rotation right?
I've yet to see evidence of "too smooth" chamber finish. Under firing pressure the case is going to compress the ejector (and spring) before brass expands.......the whole path of least resistance thing. As far as "wall grip"......take two precision ground surfaces and squeeze them together......good luck getting them apart. Just my observations over the years.
In my experience, I like to use 400grit polishing to knock down reamer machining marks and break any sharp edges that can shave jacket or brass during operation.
Not sure what happened to the above chamber. Either live with it or contact the maker. Completely your call, I've seen both extremes......shooters who can't live with any evidence of use.......and shooters that are shooting homebrew mixed part rifles because it shoots decent enough.

Will do. Believe that.I think you are on the right track. If your concerns/expectations are realistic (and I believe they are) then you need to get what you paid for.
Keep us posted on the status, customer service in this industry goes a LONG WAY.
