Hi i recently bought a tokyo marui v10 pistol, i know nothing about airsoft and i used abbey 144a maintenance gas to fire the gun a few times which i now know your not supposed to do, first of would this of damaged my gun and second of all would predator 144a gun gas be suitable for me to use with this particular model of gun specifically indoors? The other few questions i had were what is predator 144a gun gas and 144a maintenance gas composed of.. I noticed that sometimes it gives of a strange smell and foolishly i accidentally inhaled a very small amount of the maintenance gas when i fired the gun, i feel fine but is this something to be concerned about? I noticed its kinda of difficult not to get a wiff of the gas when its discharged from the gun especially when firing indoors, is it safe for me to do so or are there ways i can avoid this, lastly now that i know the maintenance gas is not meant for firing my airsoft gun how often should i use it and once im ready to fill my gun up with the appropriate gas for firing what do i do with the maintenance gas already inside the mag, sorry for the abundance of questions but im very confused, Any feed back would be greatly appreciated thank you.
