The Cartel Mod is a special edition mod featuring a telescoping double pin and three separate laser-engraved tubes to accommodate three different battery sizes. The three compatible battery sizes that fit the Cartel Mod are the 18650, 18500 and 18350 IMR style batteries. The tube itself comes in a brass or copper finish and has a diameter of about 24mm. The Cartel Mod has highly conductive silver-plated contacts and a two-way adjustable center pin. The extremely smooth throw, recessed switch design allows you to stand this MOD safely on flat surface without the worry of it firing. This Mechanical Mod is a high quality 1:1 clone.
