Mag system for 223?

Didn't know where to ask this question, so figured I'd as in the stock section. I'm going to be putting together my first 300 blackout and will be using a Savage/Stevens 200 .223 as the donor rifle. My question is anyone offering a mag system for 223? I saw that SSS offers an extended mag, but does anyone use a mag system in a .223?

CDI detachable bottom metal and AICS 10rd 223 magazines.

Oh nice...I sent CDI an email last night...I didn't know they offered it for 223...I have a CDI for my 308. Thanks, I'll give Jeff a call today.

Just to be clear, the AICS 223 magazines fit any DBM that utilizes AICS 308 magazines...they physically are the same size.

Any of CDI's 308 mag box DBMs (short action 4.27, 4.41 or LA/308 mag) will work with the polymer AICS 223 magazines.

That is good to know...I was going to call Jeff and talk to him.
