Thunderbolt

It's not possible to load additional rounds into the tube with a shell on the lifter.

Start with the magazine fully loaded and the bolt forward with the chamber empty. Pull the bolt back far enough to fit a shell onto the lifter. If you pull the bolt back too far the lifter will flip up, but you just have to push it back down and ease the bolt back forward a bit. Now place the round on the lifter, keep it held down enough to clear the bolt and ride the bolt forward. With the round just partly under the bolt carrier, slip another round in the chamber. Or you can ignore this step if you want the chamber empty. I'll try to make a video of this.

An out of the box M4 will hold 5 in the tube, 1 in the chamber, and 1 on the shell lifter under the bolt for a total of 7. The full length M1014 tube or M4 tube with extension will hold 7 in the tube, 1 in the chamber, and 1 under the bolt for 9 total.

If the price is right, count me in as well.

Don't ride the bolt forward. Pull back and let it snap forward on its own.

Neither are 1 & 2.

Nope. 922® lives on and will never sunset. This is from the ATF's website: SAW = Semiautomatic Assault Weapon LCAFD = Large Capacity Ammunition Feeding Device

I've seen that letter. It left out the bolt, bolt carrier, and the gas pistons.

It's either the pistol grip or the extension. You can't have both unless you knock down the parts count.

Just the standard type stock, no pistol grip.

It does not matter what state you live in, a functioning telescoping stock with pistol grip in still prohibited throughout the United States unless you add 5 approved US made parts or add the gun to the NFA registry. An imported semi-automatic shotgun cannot have both a pistol grip or telescoping/folding stock. This has been the law since before the Brady Bill and is still standing. You can install a US made or Italian made full length magazine tube or extension to your M4 without adding any US parts by either installing the M4 synthetic field stock or by limiting the tube to 5 rounds with a plug. It's a stupid law, I know.

The M1 and M4 are both regulated under definition of the 1968 GCA. The Nova is not.

No, you're good to go. The Gun Control Act is limited to semi-automatics. Since the Nova is pump-action and the AWB is dead, you can put whatever evil features you deem necessary.
