is ADSing slower with sights?

[ShermanR]

is aiming down sight faster with iron sights or does it just feel that way?

[Waldschrat]

Should not have any effect, unless you found a bug, because, THAT would have been in some description.

[Chainos]

Acog has longer ADS times

[THT.Felix]

No, its slower when using a vertical grip. If you want to aim faster, use the angled grip

[ShodaN]

The sight you attach does not affect ADS time.
