Some other things you need to keep in mind, or so I've found out.
Add a nordic low drag follower to your list. The stock is a crappy plastic one and since your already making a order with nordic it's worth it.
I just got done welding the bolt release button to the shell stop bar. I tightened the bolt release button screw pretty tight and the factory button started spinning instead of the screw coming out. I tried to stake it so it wouldn't spin but that didn't help for long. So I just welded the button from the backside. I would drill and tap it the send it off if you don't have a welder. Just takes a tac weld and some sanding and polishing and its good to go.
If you want to load fast there are a coupe things that I ave found are needed. The load port will need to be opened up. The shell stop will need to be bent and cut a little bit. but this is all trial and error to get it how you like it. Just takes some pliers or a vice and a hacksaw to open the flex cuts to allow it to bend out of the way easier when loaded.
