CMMG lower and CMMG upper compatibility

They fit, with a catch

The CMMG RESOLUTE MK4/ Trigger Midnight Bronze works with the CMMG Banshee 9mm Upper, with one thing to check: Lower Receiver (AR-15) needs a 9mm magazine well adapter for a PCC/9mm build.

No one has built this exact setup yet, but CMMG lowers with CMMG uppers are a common pairing.

Counted from real GunPartPicker builds: parts lists people put together while planning to buy.

Checked by the same rules the AR builder runs on every part you add: caliber, frame size, receiver pattern, thread pitch and gas length.

Fit is judged from the specs retailers list, which can be missing or wrong. Confirm with the manufacturer before you buy, and have a qualified gunsmith check any build before you fire it.

How we count ⌄

These shares come from GunPartPicker's build data: real parts lists people put together while planning a purchase, not sales or surveys. A build counts a part only when it is the final pick for its slot, so parts that were swapped out never count. Fit never comes from these numbers; it comes from our compatibility rules alone.
