I contacted CMMG by email on 12/25/22 about the Banshee firing out of battery. They responded on 12/29/22 and on 12/30/22 via email and their suggestion is to try different ammo and encouraged me to continue to fire this firearm even though I have explained to them that I believe there is a safety risk in doing so. I further explained that it’s not an ammo issue and but rather an out of battery issue. Regardless if the ammo is in spec or not, the firearm should prevent the round from firing if out of battery.

Attached are pictures of that I had sent CMMG. On 12/30/22, I requested CMMG either replace the firearm or pay me for the purchase price (I would surrender the firearm to CMMG). No response! I emailed them again on 1/6/23 and I haven’t received a response from them from that request either. I have called CMMG on several occasions since 1/6/23, including this morning, but it always goes to voicemail and as stated on their email they encourage all customer service questions being emailed to them.

I purchased this firearm in September of 2022. The firearm immediately had feeding issues with all kinds of ammo. The rear of the bottom lugs on the bolt were striking the case mouth of the loaded round in the magazine. As the bolt travelled rearward from firing, the rear of the bottom bolt lugs struck the case mouth of the loaded round in the magazine and turned it cockeyed in the magazine. When the bolt moved forward after cycling it pushed the cockeyed round out of the magazine and it failed to feed in the chamber. This happened time after time. CMMG had the firearm for about 6 weeks and resolved the feeding issue by replacing the bolt.

Does anyone have any opinions or suggestion on the matter?

Everyone is probably at SHOT

It's been 21 days since my initial request, Shot show or not.

Did they not offer to fix it? How did it go straight from try different ammo to replace the gun or give me my money back? Something is missing here.

They have never responded back to my request to replace or pay me for the firearm, not even to offer a repair it either. I have sent them multiple emails and have attempted to call them multiple times.

Friend had one with the exact same issues.
After numerous parts swap, he got a return label. 3 months later got the gun back.
Was sold with disclosure after that.
