How do you fire a rifle grenade on a PC?

Tried every thing, and how do you fire multiple satchel charges as well on a PC. I can throw 2 but have to cap them at the same time.
Rifle grenades I have no idea what key to launch it.

you have to unlock it at lv 12, it is used as attachment, and press 2 to use it

You unlock Rifle grenade attatcment at lvl 14 for all AR. AR, SMG, Shotguns and Pistols have new attacments: 2 for AR; Bayonet and Rifle Grenade, SMG's; Silencer, Shotguns; Incendiary, Pistols; TacticalKnife and silencer. All of this "New" attachments have to be unlocked for every single weapon. Then they all has to be set as an attachment for that weapon, before the game starts. Then you can put it in use by hitting "2" for them all. Same is with Bipod for LMG's.

Thanks should have guessed it worked like silencer. Thanks for the heads up.

Yeah, the other posts got it down. As for the satchel charges, you quickly double tap F to detonate one manually. This will detonate both if you have two on the ground at the same time. This is a bit inconsistent, and ♥♥♥♥♥ you over if there is a weapon on the ground near you, so I would recommend using the usual detonator unless you have a second one you don't want to throw
