Yeah I read your thread otherwise I would have thought it would sit in any chassis/stock. That was a lot of info. Thanks. I have an AICS that I'd like to put it in but don't want to have to modify any stock that I currently have. Dennis/Flatland1 is helping me out. I tried to get him to sell me his stick so he could send another 40X action to jelrod but he has some sort of emotional attachment to the thing He built my Bighorn that I've stuck in a AICS and it shoots great so I'm going to have him build an barreled action and put it in my Manners T4 mini chassis if it will fit. I knew this .22 trainer thing was going to get expensive.
