Albert @ The Rasch Outdoor Chronicles has reviewed the CMMG 28 round Immortal magazine for the AR-15:

CMMG claims that no other magazine offers greater performance under extreme conditions. It has their new stainless steel anti-tilt follower which features superb stability, minimal drag and unmatched durability.

The new CMMG braided wire spring gives 40% additional pressure over standard USGI springs. A nano-ceramic plated braided wire spring protects for over 400+ hours against salt sea spray.

I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!

    buzzwords, and siduse of them at that.

    That wire is NOT braided. It's twisted.

    Nanoseramic coating, eh? While 's robably a ceramic coating along the lines of header ceramic, it's doubtful it involves anything on the nanometer level.

    In all, probably just a bunch of buzz to "justify" $50 a mag.

    Mags are disposable items. Duh?

    hmmm, I see CMMG are being clever and selling the followers and springs as retrofits.

    $6 gets you both items. I can certainly live with that!
