This 3d mesh model was found in the game files.

Will it be added ? Or replace the current existing M16 carbine grenadier variant in the arsenal? From the images i found circa 1989 during operation just cause this appears to be the handguard used on grenadier carbines in SOF units, but i figured since its the game files this model included in the link could be added at some point anyways. ID also suggest including a leaf sight on the circular handguard as this modification also existed and would retain the same aiming capabilities for the m203 grenade launcher as the currently existing model that uses the cut down heatshield resembling the longer length M16A2 grenadier.
