Does NOT work on the BRN-180 lowers

Engineered to function reliably, no matter which manufacturers’ lower it’s mated with, the Foxtrot Mike .45 ACP Upper Receiver is forgiving enough to cycle even the most economical steel or brass cased ammo.

Foxtrot Mike Products MIKE-45 Upper Receivers are not compatible with Korean magazines or aluminum cased ammunition. Foxtrot Mike Products also does not support the use of Stern Defense .45ACP Conversion Adapter as it requires adjustment to work properly.
