3/19/2012 10:55:38 AM There will be an adapter piece that will be sold separately of the Razor Red Dot Sight so if you should ever want to mount this to your 10/22, just buy the adapter piece and it should fit nicely on the standard Weaver T-09 rail. I think that would be a pretty nice sight for the 10/22, though. Thank you for your interest and please let me know if you have any other questions. DarkNite
