Sent my Zelos back to Umarex. It has been leaking since the first time I filled it up. I fixed 2 leaks, but it is still leaking and getting worse, so I gave up. The mags are so hard to load into the gun you just about have to use a rubber mallet to drive them in. I have the worst luck of anyone my wife has ever met. I was born under the sign of the turd. The Maple mag I bought worked perfectly. Not sure what to do. I don't think they will give me back all of my money, and I spent $100 on add Ons for the gun, or they will charge me to fix the gun that they sent to me broken. It has already cost me another $30 dollars to ship it back to them. This is exactly why I am afraid to get anything besides Airforce guns, but I really wanted something with a magazine to coon hunt with because they can be tuff little guys. Oh well now the waiting starts to see what they have to say after they get it.
