*NOTE:  Some .22LR, 9mm and other blow back style upper receivers use a groove in their BCG that is too narrow for the polymer hammer that comes standard on the New Frontier Armory LW-4 complete carbon fiber lower receiver.  In these cases you will need to switch to a blow back style hammer available by clicking HERE.  The blow back style hammer, once installed, will run all rim fire and pistol uppers, and still work fine with standard mil-spec rifle uppers.
