The AR platform has been around WAY more than 30 years. It’s nearly double that since Colt lost the patent and every weapons manufacturer came up with their own version, but the original Armalite went into production in the late 50s.
They’re great firearms, fun and easy to shoot, simple maintenance, and bulk ammo is relatively inexpensive. They’re a little underpowered IMO, unless you step up to 300 blackout, but great fun for varmints and plinking. They are popular for a reason. They’re good general purpose firearms that most people can afford, are fun to shoot and have tons of accessories available. If you’re scared of them don’t buy one.
The whole "defense against a tyrannical government" is merely a romantic notion these days. A fantasy.
Tell that to the Pashtuns, or Vietnamese. Not much romantic about the US losing wars for 7 decades. You think our government forces could take on a highly armed and trained citizenry when we couldn’t take sparsely populated areas defended by a handful of goat herders/fuckers who break 5 times a day for prayers. The US federal government has zero chance of subduing the population, by design.
Banning weapons wouldn’t have stopped this shooting. Admitting trannys are mentally ill, which they are, instead of glorifying and “confirming” them would’ve.
