So we've already touched on ethical and legal issues with a SHTF scenario. Here's my next question: Scenario: it really is a SHTF situation - rioting in the streets, looting is happening, and general meltdown and the authorities have no control. Question: Would you take that pistol/shorty upper from your AR and put it on a rifle lower illegally if it allows you to have a versatile but somewhat concealable firepower at your disposal? This is just a hypothetical question for discussion. I sold my AR pistol long ago.
