Hmmm, very interesting at that. I didn't even know you could?

Don't know what the default key setting is so look in the controls; think it's called Prone. When you have the rifle selected, you can go into this position. Oddly, you can't from a crouch; you have to be standing THEN you can get intothe Prone position & the BiPod gets unfolded.

Can you make a video or osmething, I tried as you said but didn't managed to open it.

I know it unfolds in SP automatically when doing the missons but, is he talking about unfolding it in MP? I don't see that clarified here. Just that he saw it in a video.

when I play the sp it unfolds automatic, but when im playing mp I cant find the key to open it, I think you cant open it :\

I don't think you can either. MP isn't set up like SP is. You got to move and hold your weapon and practice your steadiness.

Yeah, well I think ill just find a high spot where I can prone xD

Is this bug 2 years later already present?
I am using the RON B107, with bipod, but in every Mission I am not able to use it.
In the wheel menu with equiped Sniper, the game shows "no equipment"

I’m having the exact same issue but it’s also with all the other rifles too
