In times of civil strife or disobedience that TRG is about as useful as a flat tire. By the time you racked a shell ito it and lined up, you'd have 20 rounds from a gas gun permeating your forehead. Dang hard to see in a scope when your brains are running in your eyes.....
A little known fact, but true is AR platforms are touchy about being clean, About 60 rounds of questionablt orign ammunition and things start to get dicey.
Conversely, my Mini or an AK or an SKS cares less about cleaning the action. In fact, other than an ocassional douche with brake cleaner, you never have to clean the action and the barrel is a qucik trip- with a boresnake.
I look at an AR platform is sort of an extension of the male sex organ or to make up for the lack of one of substance.......
Reality is, there is really no need for that 'go to firearm in 99% of the population, pro firearm or not.
When the end comes, if it comes, you won't know it until it bites you in the ass anyway.
Better to support oragnizations like the NRA, write your Senator and Congressman and don't vote in any candidate that don't support the Second Amendment.
As was stated previously, one man armies don't last very long and always keep in mind that if you shoot at someone, chances are, they will shoot back.
