There are 2 different ways. First, you can use your
..cfg/gungame51/gg_en_config.cfg to override the values of the second way to do this. Inside that config, look for :
// ============================================================================
// >> MULTIKILL OVERRIDE
// ============================================================================
// Notes:
// * Keep this variable set to 0 unless you want to override the
// values you have set in your weapon order file.
// * This will not override hegrenade and knife, these are always 1.
// Default Value: 0
// The amount of kills a player needs to level up per weapon.
gg_multikill_override 0
The second way is just what PabloP told you. Go to whichever weapon_orders files you are using. Then, next to each weapon, put the number of kills necessary to level with that weapon. Note, in your
..cfg/gungame51/weapon_orders/default_weapon_order.txt it states:
//----------------------------------------------------------------------------
// Weapon order file -- Defines what weapon goes with each level.
//
// The order of the weapons below will define what order the weapons will go
// in on a #default weapon order rotation.
//
// #reverse makes the weapon order go bottom to top, with the knife and
// hegrenade being last.
//
// #random makes the weapon order a random order, being re-randomized on
// every map change.
//
// The first line of each weapon order must be:
// => Weapon order name here
//
// Format: <weapon name> <multikill>
The <multikill> value is what we are talking about. If you just have the <weapon name> it assumes the value of <multikill> is 1.
