Does the PSA Lower 300BO work with the ABC RIFLE COMPANY AR9 9mm Luger Pistol?

Palmetto State Armory lower and ABC Rifle Company upper compatibility

They fit, with a catch

The PSA Lower 300BO works with the ABC RIFLE COMPANY AR9 9mm Luger Pistol Billet, with one thing to check: Lower Receiver (300 Blackout) needs a 9mm magazine well adapter for a PCC/9mm build.

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.
