Hi all, I hope all is well. I am in the process of buying a 556 pistol. I want to convert it to an SBR. From what i have read i can install an AR buffer tube and stock but I was curious if it is possible to install the Swiss style folding/adjustable stock? I have read i can swap out the lower but is their an option without doing this? If anyone has links to the parts, etc it wold be appreciated. Thank you.
