Much like >:3 mod: https://modworkshop.net/mydownloads.php?action=view_down&did=17011

It would be great if someone could mod in the RMR sight (or any small optic sight) and positioned like the 45 Angled Ironsight gadget.
So when aiming the 'backup' sight, the weapon is turned 45 degree or so.

If you want some visualization, its like the Hybrid Sight of RSASS in CoD: Modern Warfare 3 campaign.
