Finally got a keeper. This Katana arrived in great shape without any obvious QC issues. I promptly check all the screws and cleaned the barrel with Goo Gone. It took about 10-12 patches to get the barrel clean. Then I mounted a 4-12 Bushnell Banner on her. Tried to stay with a light weight scope that has reasonable clarity.
The weather is rather balmy here in Wisconsin today, a reasonable 25 degrees with no wind. That made the sighting in bearable. I aired it up to the max fill line and shot it down to the lower line. That's about the same time the fingers got too cold to load her anymore. Didn't mess with the Chrony, there will be better days for that.
I'm most impressed with the shoulder ability of this air gun. Just seems to come up nice and fits my 6 ft frame well. I like my air guns light. This combo fits that bill to a T. It should be a nice hunting setup. Accuracy appears very good. We'll see what it does when I can stretch it out more.
All in all I'm glad I took advantage of the Black Friday sale at Pyramyd Air and got mine for $331.55. Pyramyd Air has lowered the price on the Katana. I'm thinking they will come down some more since the Marauder is now available for less too.
