No, this does not include a pistol brace or stock. To add a stock would require you to register it with the ATF as a SBR/short barreled rifle and require a$200 tax stamp. Not sure if you heard but at the moment same applies for pistol braces since the ATF reclassified them as stocks basically. Sorry but hope this helps.

Hi and welcome to the Buds Community. No Stock or Brace included Sir. Depending on final ATF court ruling regarding Pistol Braces, just for info : omahaoutdoors.com/sig-sauer-mcx-mpx-folding-pcb-brace/ - Cheers and stay safe!

No sir, there is no stock or brace included. You would have to buy that separately and pay a $200 tax stamp and register with the ATF, as adding a stock will turn this into a short barrelled rifle.
Stay safe & have a great day!

No it’s a pistol
