I've come across two options for a new firearm and I am going to apply them as a back up home defense weapon. One is a lever action shotgun chambered in .410 and the other is an AR15 pistol.
My questions are: is the .410 severely under powered compared to the 12gauge, is 223 or 556 as powerful out of a shorter barrel, can upper and lowers be exchanged between AR rifles and Pistols legally without paper work, and is it as accurate without the stock or with an arm brace?
