Wolverine Airsoft Inferno Gen. 2 M4/M249 Nozzle for Inferno Gen. 2 Engine
When the Inferno Gen. 2 was developed and new nozzles were designed for it, it was found that the M4 and M249 nozzles were too similar, so it was decided not to create separate nozzles for each. For this reason, no Inferno Gen. 2 nozzle is specifically marked as an M249 nozzle.
