xchambers go anywhere from 2 stage or cell upto 18 stage/cell. A 2 cell is like what would come on the xchamber/gas thru foregrips on spyders and spyder clones. If your only option is currently to run Co2, then Id suggest trying to find a 8 stage/cell but if you cant find one a 6 will work good enough. A remote + xchamber really expands your co2 to a gas and even more so when its hot out which will drastically increase your shot count.
