This launcher works great for using Taginn C02 shells, they are a little snug but they fit. Make sure you don't over tighten the plastic tube to the base of the shell or it will not fit. Orange tip is easy to remove, i used a vice grip so squeezing it off works well, but keep in mind removing it will make the barrel cap that is attached to the launcher useless, i cut that off as well. Solid construction and looks exactly like the real thing, even has most of the correct trademarks. MMI makes a holster for the M320, i picked one up on eBay used and it works perfectly. Would absolutely reccomend this launcher for use at a milsim, and highly reccomend airsoftjunkiez.
