Type: R.I.S.
Classic Army M249 Upper R.I.S.
To complete the MK46 Mod0 look ala Ghost Recon Advanced Warfighter, I added the Classic Army M249 Upper R.I.S. unit.
Classic Army M249 Upper R.I.S. "Closeup"
This is an all metal unit and very easy to install. A drawback is you need to remove the upper R.I.S. to remove the barrel. Another drawback being the added weight of the all metal R.I.S.
