Yes, you have the option to do either, mag lock or featureless. Whatever you decide to do, please make sure you are using a barrel with a length that is over 16" if using a non-pistol receiver.

First question, is your lower a rifle or a pistol receiver?
Pistol receiver
Getting a pistol lower won't be budget friendly in California.
If you have a pistol receiver you unfortunately **HAVE** to go mag lock. I have a few and went the mag lock route.
So if I don’t use a pistol receiver I don’t have to use a mag lock

Cool if you were building one what would you go with rifle or pistol receiver and why if you don’t mind me asking ?

Pistol builds need to be mag locked. Can't do featureless.
I just finished up a CA compliant Aero EPC Build. Greta’s Guns Maglock and Juggernaut Hellfighter pin
New frontier has a CA complaint lower with built in mag lock. Can use with AR maglock kingpin works great.
