If you are refering to where it is sold at, thats easy. Freelancer/data/equipment/market_misc and locate the base you wish to sell it at. Find the name of the wep, and insert it with level requirments.
Sample -
base = CR01_0_Base
MarketGood = Civ_weapon01_mark01, 0, -1, 10, 10, 0, 1
If its a newly created wep, or a modified in game one, do you want to change price? If so see in the euipment folder, Weapons_goods and add it there for the price. Sample - [Good
nickname = Civ_weapon01_mark01
equipment = Civ_weapon01_mark01
category = equipment
price = 500
item_icon = equipment\models\commodities\nn_icons\EQUIPICON_gun.3db
combinable = false
ids_name = 564727
ids_info = 564727
shop_archetype = equipment\models\turret\tie_laser.cmp
material_library = equipment\models\li_turret.mat
Hope this helps.
