If I have a fixed mag AR, can I put a folding stock adaptor? Just want to make sure since it does make the rifle easier to store and shorter.
 
Pretty sure that's a no-go from what I remember. OAL is measured from most compact functional configuration possible. Folding stock can technically fire 1 round folded so it's considered operational. I think the law is 30 inches minimum OAL in California.
 
Not if the rifle is functional and OAL is <30”.

I have a Kel-Tec SU-16CA that folds to 25”, but the rifle is non-operational when folded.

Yea that’s what I figured. I’ll stay away from those
 
You either need a long barrel or P&W a muzzle device to get to the OAL length. I have a BRN-180 that I had to P&W one of those long JP Enterprise flash hiders to fulfill the OAL requirement.
 
What if the gun is registered as semi auto pistol?
 
Federal measures rifle in longest configuration. I.E. with stock out "unfolded" and extended (if collapsible). 26" mimimum

California being California makes you measure with the stock folded and/or collapsed if the rifle can still function/fire in that configuration. 30" minimum
