These maglights are real equipment that are inexplicably missing on RB6 weapons. The terrorists even carried them in Raven Shield.
The night vision modes are ok but shouldn't be available when the player isn't wearing goggles.

I want the next RB6 game to have taclights and where do I request this to the right people?

There is really nowhere to request it since the Ubi devs for R6 don't listen to us. There was a puppet named Goliath that posted here in the Lockdown forums but when that game phailed he left.

Yep and he never came back.Hes a guy other developers should look up to.
