The pointers on all 3 of those weapons are all misplaced and not on the rail.

This is fixed on the SPMG and Navid, but the SIDE proxy (for fitting IR lasers, flashlights etc.) is still misplaced on the Cyrus.
The proxy just needs moving a couple of cm upwards.
This is resolved so I don't see why it isn't closed...
