== AR-15 weapon categorization ==
Depending on the selected configuration of modifications, your AR-15's weapon category may change. * If the weapon has the '''DMR'(WIP)'', '''Sniper''' or '''SPR''' upper receiver modification, the weapon category changes to '''Precision rifle''', regardless of any other mods installed.* Otherwise, the weapon category depends on the fire control group. If it is '''Safe/Semi''', the category changes to '''Conventional rifle'''. Any other configuration is a '''Combat rifle'''.
