Where the heck are you guys finding R-22 rifles??? I would give my left nut for one, and you found a second!!! I'm happy for you guys but man I'm envious. I think the R-22 could be a good platform for a rim fire mp5. A little chop or replacement of the fore end and if your up to it an operating lever on the front left side of the for stock would be sweet. Heck cut a notch for the HK slap. You could also look to Specterarms s2 for inspiration. It looks a lot like an mp5 but the R-22 is closer. If you are anyone here wants to part with your dear R-22 just let me know what organ you want. (that does not sound right). Please think twice before you start cutting up a rare R-22.

I want my mp5 to be completely restorable to original
My first R22 had around 100-200 rounds down the pipe and came with a bushnell holosight for 500$ both are relatively rare and was on the EE for 3 weeks, the sight alone sell for 300$ on ebay from what i've seen.
I've already been ask by pm to do a DIY for my mod so i'll make a little photo thread when I get started (when I get mine in the mail)
