Hi. The GRU is using the wrong defindex. The weapon had a new defindex when the Jungle Inferno update came in. The current defindex "1184" on the Template:Dictionary/defindex page is now used exclusively to the robots on MVM. The new index should be "239". Due to this, clicking to purchase the weapon on the page does not work, as it's redirecting to the old defindex.
Was going to update but saw that the page is automatically replaced by this bot, so.
