Sorry, I won't be able to help you. If you read my other posts you will see that my order for the Zelos through Midwest Gun Works was one that was cancelled due to their lack of an inventory control system. Impacted multiple folks in the AGN community.
I kind of got tired of trying to find and buy a Zelos for a reasonable price, so I gave up. I don't recall exactly where my Zelos money went, but I think that I may have used it to buy a beauty of a little gun - An FX Dreamline Classic in .22 which UA was clearing out (closing out?) during their Labor Day sale for something like $749 (brand new) with free shipping and no sales tax. That gun is a known commodity to me (my wife shoots one in a laminate stock), and I knew that the lighter synthetic stock would make it an even better light hunter. I already knew its accuracy potential, and the new gun has not disappointed.
So no Zelos for me. Some folks love them but others are having the normal Umarex/Snowpeak problems, which I can truly live without.
