MSG SA-01 Weapon Mount w/ Super Rare Swing Arm. Hmmwv Polaris? For Sale

This is a milsys group product. Never seen a super light weight unit like this. The mounting bracket is heavy but the cradle and swing arm are either titanium or a lighter aluminum. These are super light. The lever for the swing arm is broken and part is still on the mount in the photos. What you see is what you get. It’s discolored as if it’s been in or near a fire. Not sure. Not sure what the mount fits. Hmmwv, Polaris rzr, GMV.
