Hey every one...
I found this forum just a couple of days ago... I had my 1077 for about a year now. The only add on I have for it is a bushnell 3-9X40 scope. It's a really nice rifle with the exception of being underpowered (canadian version that is). I don't really know much on modifying air rilfes but I'm sure some one on here knows. I took some pictures of the internals of the rifle today so that you can check it out and maybe spot a diference from the us version. As far as I can tell by changing just the valve it would bring it to us power. That's all for now. Let me know I should post a picture of another part.
