according to this 922r chart
It looks like there is (16) 922r parts on a typical AK. My NHM-91 does not have a muzzle attachment, or pistol grip bringing that count down to 14... (I think that is correct anyway)
With a US made mag (3 parts), that brings it down to 11... so I guess I need to add another compliance part to get the count to 10?
So... by using US mags, even though I am reducing the "foreign parts" count, it opens up that whole 922r can of worms, and then I have to swap out parts to get it at of under 10?
