Scorpion kak tube and at stocks?

[Acsr]

Have a pistol scorpion with the kak tube and the shock wave. Was wondering if there is a ar style stock that goes over the kak tube.  I noticed it's a bigger od then a standard stock.  Maybe it's necessary to modify a regular one.   Thanks for any info.

I assumed they made the tube diameter larger to keep people from putting stocks on them for legal reasons.

I believe that may be the reason as well, but when sbr'd it would be perfectly legal.

Yeah, there arent really any options for that. Interesting choice keeping an AR buffer tube style stock when you can go with other options.
