There's always going to be the enthusiast & hobbyist (or what is sometimes referred to as novelty) owners who will find some way around whatever impediments are imposed. Ditto the gun companies probably coming up with yet more configurations that won't violate the statutes, as written.
I bought my only AR back before the first of the state's (or federal) "assault weapons" laws ever passed. I only bought it because the state was talking about creating the law, so naturally, as a younger man I took umbrage and went out and bought one (which I dutifully registered when it came time to register it under the new law).
Now, I rather wish I'd put my money in something else, as I got
more than enough opportunity to shoot and support AR's as a LE firearms instructor (teaching various patrol rifle classes over the years), and having attended 5 armorer classes for the AR system.
Now, aside from having to do so, that's the
last rifle I have an interest in shooting for enjoyment. It became a skills-maintenance task, not something done for "fun".
Other folks certainly feel differently, though.
I wasn't at all surprised by the
huge numbers of people buying off-list rifles and lowers in bullet button configuration, anxious to get in under the cutoff for the last of the sales here last month.
Personally, I'm still thinking about taking my AR out-of-state and selling it to licensed store front gun store, and using the money to buy some interesting, fun and practical rifles ... like another lever gun and maybe a new take-down Ruger .22LR semi rifle.
I got the whole AR thing out of my system, so to speak.
Don't get me wrong, as I don't personally agree with removing them from availability for private ownership, but when a state passes a law, unless it gets overturned, it's the law.
In one of my armorer classes we were once asked, by the instructor (a retired cop), about an informal "poll" (not requested by the instructor's company) of the long gun we might wish to own/possess in the event of total, long term social breakdown. He said he was just curious about how his LE students thought about such things. He went around the room asking for individual answers, and any explanations, if someone desired.
The significant majority of answers he received was "M4". I think I remember maybe 2 guys giving some variation of the SKS system. A couple 870's were mentioned.
When he got to me, I answered ".30-30" (no brand offered, just the caliber and obvious inference of it being a lever gun). When he asked why (and most all other eyes were one me), I basically replied that the cartridge was more than adequate for any relatively short-range (out to 125yds) needs I might perceive; the rifle didn't require box magazines; lever gun capacities were pretty reasonable for capacity & caliber; and the caliber was pretty ubiquitous across the country.
I also gave him the line attributed to the character (real life figure) of Command Sergeant Major Basil L. Plumley in the movie "We Were Soldiers", regarding how if I ever really needed an AR, there would probably be no shortage of them to be found ... (as I looked around the other eyes in the room
), considering all of them in both government and private hands.
