CA compliance parts

[CWINSD]

For featureless I use Sparrow, a comp, and a rubber stop for the stock. Otherwise I've had no issues with the CompMag.

all of the options suck...However train train train with your kingpin or Jugger you can get pretty fast with reloads with practice... buy an sig regulator!!! from 2A zone... they are fun and worried free and again you have to train with it

Sparrow or juggernaut grips

They are different - like Coke and Pepsi. Try both and your hand will prefer one over the other.

Hogue freedom fighter trumps AR maglock for the actual magazine locking job because it works with any upper.
Hogue freedom fighter keeps the bolt catch functional unlike the Juggernaut's mag lock piece.
Kingpin is harder to install/reinstall than Juggernaut's Hellfighter rear pin but Juggernauts rear pin is 2 pieces.
I personally recommend the Hogue Freedom Fighter combined with the Juggernaut takedown pin because it is easier to separate the upper from the lower without any tools and I like that the spring works more positively because it does not bind on the pin like the kingpin provided spring does.

Came here to write this exactly!

But I’d choose featureless over this, unless it’s a pistol

IMHO - All of these modifications are dangerous and against SOP for clearing a jam, FTE or FTF. Can't drop the mag unless you open the action. Can't open the action if you can't get your bolt all the way into battery. And opening your action with a FTF is not the wisest choice.

Plus RSO's hate when they call a line break and you gotta cycle through the remainder of your mag (shooting or manual ejection).

Hogue freedom kit + juggernaut pin fixes this issue

That's because of the bolt catch being gone.
I use only the takedown pin from the hellfighter and install a hogue freedom fighter mag lock which leaves the standard mag catch/release and bolt catch in place and only blocks the mag release button when the upper and lower are pinned together.
When you press the spring-loaded takedown pin in 1/8", then the upper pops open a little and lets the mag release work.

EXACTLY!
