I have own 3 different t8s, one t9 and t8.1 is on the way. But I recently picked up another t8 w/ 2 mags and offer gear. When I air up the co2 grams into the mags the hold the air no problems. Then when I prceed to pop in the mag it dumps the air. This has never happened to me before. Any help??? If so lmk....if not I will call tiberius in the next week.
