I want to attach a sling to my gamo shadow and i was wondering if this would work?

http://www.pyramydair.com/cgi-bin/accessory.pl?accessory_id=1124

If it dosnt, what would be the best way to go about adding a sling? Also, do the shadows that they are selling on pyramid air have the rear stud on them to add a sling. I want to get another shadow and have it tuned and swithced to .20 to use as my new wintertime hunting gun.

And my last guestion is about my gamo viper express shotgun. I have a hard time picking up the bead when i am shooting with it sometims and i want to know if a aftermarket regular shotgun bead like a true glow would fit on it? thanks for any help guys i really appreciate it.

No, at least not the one I got about 6 months ago. The box had a picture of a gun with one but in reality it didn't. Also, the butt is not as pictured on the website. It's the same one thats on the newer models with a few holes going down it. Also, mine didn't come with a scope stop, instead a small metal piece, so I emailed Gamo and they told me to give me their address and I had a free one within a few days. And as for your third question, I know Gamo sells rear sites, but they might be the same that you have now.
