The Constitution requires Congress to provide for the arming and training of the militia. Since Congress ALWAYS follows the Constitution, I assume you simply make your Congressperson aware of your AR’s stiff trigger pull, and he/she/it will dispatch the BATFE armorer to tune her up. Since it’s an election year, they might bring some free cigars, whiskey, and C4 to go with that.
“The Constitution requires Congress to provide for the arming and training of the militia.”
The Second Militia Act of 1792 says you will provide your own rifle, but we know that they only meant water and nerf guns. We don’t want to scare the snowflakes.
