35 new scopes are added, I think that is all of them. Let me know if anything is missing.
The turn speed is currently bugged, so hipfire calculations might be off.
Here's a few things I tested:
Backback with 2% reduction - 2% measured.
Helmet with 2% reduction - 0% measured.
Same 2% helmet with facemask 4% totalling 6% reduction - 6% measured.
Body armor with 5% reduction - 0% measured.
Same body armor with 5% and 1 plate with 1.5% totalling 6.5% - 1.2% measured.
Same body armor with 5% and 2 plates with 1.5% each totalling 8% - 2.4% measured.
It seems quite random what works and what doesn't, so it's not possible to account for this in any way without testing each specific setup.
