The mec_bipod? A D-Day Map for vanilla BF2. Kinda Strange, but whatever.
Anyway, YES, make a copy of the weapon, put it in your map folder and make sure to load it with your map, try increasing the basic temp for the weapon's ai config file. The vanilla emplacements/stationary guns have a basic temp of about 5 I think, FH2 MG42s for example use 250 (!). I'd advice that you compare both ai config files and see where the differences lay that might help you to get the results you wish for.
