Where can Edit Function for Weapon ?

Hi, i have one weapon with the function of mounting to the ground

weapons/mp/
This is:
mg42_bipod_duck_mp
mg42_bipod_prone_mp
mg42_bipod_stand_mp
mg42_bipod_walk_mp

Where i can edit script functional for weapon ? (folder and file(s) )

Hello. It's a custom weapon from from some mod (AdmiralMOD, I guess), so scripts can be anywhere, in any .gsc file. As I said to you before, you can try to start search it from _weapons.gsc file.
