I need some help with my markers - geo and geo2 :
Last week at an event the both guns started acting strange - first the geo2 when firing after 1 good shot the next 2-3 shots were really low (the sound that the guns does is a little puff, you know that sound
) and again one good shot. It has happened to me before I assumed low battery. This week it happened again with both guns now the geo2 does one good shot, few not full shots. The other gun's bolt is doing almost the same but the bolt is sticking after few shots and it's leaking air. I tried new batteries and wiping the lube from the bolts. It works alright for few shot's and the the same problem. Any idea what might be the problem or what to do next? Maybe change all of the o-rings?
