Metal gas block for outer barrel of M4 / M16 rifles by FMA

This metal gas block from FMA is designed for airsoft replicas of M4/M16 series rifles, but if the barrel diameter is suitable, it can also be used on other types of guns.
The gas block has an internal diameter of 18.9 mm and is secured by two set screws underneath, ensuring a firm hold on the outer barrel. This component primarily serves as an imitation or holder for a mock gas tube on free-floating handguards.
Not suitable for use on real firearms.
