Yes that's a good reason to get those parts also. My trigger kits are Tapco. I'll have to read through the parts compliance again to be up on all the requirements.

Yeah most definitely! P22r only counts certain parts. Basically if you have a muzzle device you need 6 U.S. parts (your receiver would be one as well). Hopefully you have 2 more countable U.S. parts somewhere. I would recommend a U.S. pistol grip, stock, handguard, or muzzle device. Stay away from U.S. mags unless they are US Palm (even then it is debatable). Here's a calculator for 922r.
It is designed for Saigas but still works
http://jobson.us/922r/Note that 922r applies when you go to the "evil assault weapons" configuration of a pistol grip AND/OR (by those who read the law strictly) when you insert a magazine over 10 rounds for a rifle or over 5 for a shotgun.
After listening to the show, I looked up the site and have to admit I like the price on the kits, I wonder what is the availability of the cartridges, spare mags, etc. Mainly cartridges and are they all lacquered steel or are any brass? Can't shoot steel at many ranges. The ballistics of the cartridge are appealing and the idea of the hollow space to promote tipping on impact but still seems like once you get over the initial price of the weapon that the AR value of availability is strong.

7.62x39 and mags is very plentiful. 5.45x39 in ammo and mags not as much but is cheap if you get surplus. Not much any more is lacquered, it is mostly polymer coated. AKs have no problem with steel cases. Ranges that say no still case annoy me and I don't go to them with my AKs.
The hollow space is common to 5.45x39, not so much to 7.62x39. In fact older designed ammo (M43 cartridge) rarely tumbles. Newer modern FMJ and HP has an airspace, while the Wolf Military Classic HP ammo performs somewhat similar to M193 5.56mm in that it will fragment and/or expand under 100m.
