A CAR buttstock will remove and reassemble with the ratcheting plier of the SOG Multi-tool, saving you the need to carry the little wrench. Shtf, no reason to care about "toothmarks' on the locking ring. Removal of the regular AR stock is considerably more of a PITA, and concealment of the latter is pretty much out of the question. The CAR'S buttstock also allows you to adjust length of pull for other shooters, or for use with body armor and pack harness.
