On the topic if today’s citizenry being outgunned by the military:
I had the privilege of growing up in a shooting family where guns were just part of life. As such, I’m kind of the resident gun guy in the circles I hang with, and get asked often about suggestions on guns to buy.
I have had a lot of friends ask me over the last few years what AR-15 I think they should buy. This question usually comes up during political “gun grab” scares, or times when the ammo market is running dry. My answer to them is usually to talk them out of an AR-15 altogether.
The reasoning I give has to do with what you envision yourself doing with it. If you’re looking for something strictly for home defense against baddies, or something to go plink with at your local range or buddy’s property, there are much better choices. If you’re serious about getting into a gas-operated .223 like an AR-15, you need to understand the cost of ammo; how to maintain it; whether or not your local range will let you shoot it there (many indoor ranges won’t); whether your wife or teenager can pick it up and operate it with minimal experience; the dynamics of over-penetration in an urban setting, etc.
By the end of the conversation, I’ve usually talked most people into a 9mm carbine and call it good. Cheap ammo, easy to find, light recoil, easy-to-clean blowback action, fun to shoot for all ages and builds, etc.
Aside from being an actual gun enthusiast or sportsman (long range competition shooter, etc.), there is only one other situation where I think owning an AR-15 makes sense for Joe citizen, and that’s if you’re actually preparing for the expectation of armed conflict – either in the form of civil conflict or invasion from a foreign aggressor, where having a 200-500 yard combat rifle in a chambering that makes ammunition readily available during such a conflict is a good thing.
But you see, that conversation becomes more theological than it is about gun advice. By then we’re asking questions about the Christian’s role in armed conflict, the topic of just war, the topic of justified resistance against governing authorities, etc. What would you see yourself actually doing in the event of a civil war or invasion from a foreign aggressor, dear Christian? Once you have answered that, then we can talk about if an AR-15 makes sense for you.
