JETSECAM 5MP Action Camera Lens 25mm FixedÿM12 1/2 Inch IR Filter For Gopro SJCAM Camera Long Distance View

Will this fit on the RunCam 2?

Does anyone know where can you get the plastic locking nuts for the lenses? I sure it is avail here on Amazon but cannot find them?

May I have a picture of how it looks when In use

Does this come with a ir filter installed? From the pics it looks as if one is installed. Thank you
