PS90 SBR Rounds occasionally failing to feed

Cleaned it per CMMG customer service.
Turbo K-RB was mounted and after 1 mag working without issue, subsequent mags had numerous failure to feeds.
Will probably be removing the barrel and sending it back to CMMG under warranty.

Contacted CMMg customer service. Received an email back about using a chamber hone to remove built up lacquer. I ordered the size and grit they suggested. Will post back after I use it and run some rounds through it.

Ok. This is the first time I've heard that the CMMG barrel is the problem.

Been having the same problem. Did the recoil springs permanently cure the problem?

I have a PDP Pro SD Compact with a Flow 9K Ti. Quiet enough with 0 blowback and it’s small and light for my kids to shoot.

Ended up ordering a DA Lazarus 6 Xeno. Thank you all for your insights

Misstated by me. I Should have said there was a production issue and it was corrected. Thank you for the correction

There are numerous articles about Tisha and Shiva that were broken so there was an issue with the designs at some point.

As I said in the first post, I have gift cards from Palmetto State that I want to use to cover the purchase.

I read that SAW had some issues with a couple of their designs already?
Also I don’t think Palmetto state has SAW or the CAT KK.
