M240 Machine Gun: Need a BFA Discriminator?

BLUF: Properly use the M240 machine gun discriminator
 

This article from May 22 was updated 8/10/2023

The discriminator will be added to the M240 machine gun additional authorization list (AAL) according to TACOM.

The discriminator can be used when firing your M240 series machine gun with a blank firing attachment (BFA).
  • When using the M21 BFA, the chamber and discriminator, as an assembly, are mandatory.
  • When using the M24 or M26, the discriminator is optional. Use NSN 1005-01-700-0177 to get the individual discriminator.
