I'm looking for help with the mod. Please read the discussion thread I made if you're interested.

Any info about planned updates? By the way, how about making some more 'DMR' kit, especially for FAL (there is already marksman foregrip/barrel in game) and Galil?

Ahh, that must be where I'm going wrong. Thanks! ^~^

It acts like a gadget, so you have to toggle your gadget key to cycle through it.

Already activated there, but it doesn't seem to be doing anything, unless I'm pulling a dumb. I've tried it with both the Combat Sight, and the Mispec Scope, using the corresponding settings for the relevant sights, yet still no instructions on how to actually switch /over/ to the backup irons.

Mod Options > YOMC Mod Options > Backup Irons

"So, yeah, I think."
Anyway, out of pure curiosity. Are the backup sights actually functional? Or are they just there for show at this point? I presume they are functional, due to the wording, however I can not find nor see a way for them to be activated.

It will work regardless of whether you are host or client. It will announce itself in your lobbies whether you are a client or host but you can turn this off if you wish (Highly recommended you do not but you can if you want to anyway). Feel free to use this in crews there is no issue at all.

How does this mod work with multiplayer? I'm pretty happy with what your doing, and would like to share it with the crew I normally play with.
