I ended up with a Ruger Charger for a pretty reasonable price and it's one of the newer ones with AR grip and I don't like it. So I thought it would be neat to put it in a stock that would allow for the sig or shockwave brace would be cool. A very quick google search on my phone didn't come up with much specifically for the charger but I assume a 10/22 stock that allows for an AR buffer tube would work. I would just obviously have to remove the adjustable stock and replace it with a brace of some sort. Anyone done this or have any suggestions?
