Frequently Asked Questions

What is the action type of the FNAB 43 submachine gun?

The FNAB 43 submachine gun operates via a closed-bolt, lever-delayed blowback system. This mechanical design helps to delay the opening of the bolt, allowing chamber pressure to decrease before spent casing extraction.

How rare is the FNAB 43, and what were its production numbers?

The FNAB 43 is considered very rare. While some sources suggest 7,000 were made, serial number evidence indicates that only approximately 1,000 units were actually produced, making it a scarce firearm.

What type of magazines does the FNAB 43 use?

The FNAB 43 submachine gun is designed to accept standard magazines that are compatible with the Beretta 38 series of submachine guns. This allows for some magazine interchangeability.

What historical significance does the FNAB 43 have?
