At the beginning of the revolution, American citizens could possess all of the terrible weapons of the soldier.
Private citizens could own cannons, rifles, swords, anything their devious little minds could think up.
Hell, even private battleships were not unheard of. Ever hear of a Privateer?
Its absurd for a bunch of farmers with bolt guns to claim parity to modern forces armed with tanks, artillery, air support, not to mention the numerous layers of support and logistics that go behind all of these things...
I think many people miss the point that the second amendment was meant to be an obstacle to tyranny by means of the factor of fear and cost. When those same farmers have access to all the of the terrible implements of war.. it is another story.
A few farmers with bolt guns can be crushed in any serious engagement, whatever crap has been spread around about resistance to tyranny. They are not an obstacle, they are not a source of fear.
Hell, have you considered that the bolt action rifles you fellows claim will work so well for "sniper" roles will not penetrate the body armor of average soldiers as it presently stands? We're forbidden "armor piercing" ammunition for our own good, of course. I know, I know, head shots... On a running target that is shooting back from an unknown distance. It sounds a hell of a lot easier then it actually is. Whats more, helmet protection is advancing along with everything else.
In 20 years, who knows what technology will bring along. We could have body armor that is completely impenetrable to the weapons we are presently using. They already have liquid spray on body armor... they already have devices that can detect and triangulate the exact location of a gunshot.
Can you imagine what 20 years will bring? We are being held in a state of technological homeostasis by our generous benefactors in government. While we send in our dues to the NRA, we do nothing but sustain the status quo. It is a losing proposition.
