Estonia’s NordArm launched a blank firing adapter for the .50 cal M2 Browning back in 2021, they have now announced the introduction of an improved GEN 3 version of the adapter. The latest iteration of the adapter introduces exchangeable gas nozzles, while this might not sound particularly significant or exciting it’s useful for enabling the blank firing adapter to use all blank ammunition types available on the market – these range from brass or plastic cased and various loadings of gunpowder which can impact the reliable cycling of the M2 when firing blank.
