My next question may seem over kill on my knowledge on the 922r compliance parts list. The following list is what I have on my build. There's no pistol grip at the moment, as I have it in a rifle configuration, but I do have one for it. Also, even though I know I don't need to have one on there, is a Solar Tech BB.
Magazine, floor plate, and follower.
In total it's 12 parts that I've got. Is it six (6) parts to make it all 922r?
Would big brother really take a count on how many there are?
Or are they making us whistle Dixie?
