Ask a Question
  • Assume this will be compatible with any .300 WM, AICS equipped rifle, such as my Begara Premier Ridgeback in .300 WM?

    Yes that is correct.

  • Will 270 caliber fit this magazine

    No i believe you would want a 30-06 aics magazine and then need to bend in the feed lips for the magazine to hold the rounds in place.

  • Are these magazines compatible with the 300 prc

    No sir, you'll need this magazine

  • Will these work with factory loads. 28 nosler 162 gr hornady precision hunter.

    I believer you will want this magazine in .338 LM with 3.850" length.  I would double check and ask MDT themselves about your .28 nosler just to be sure.

  • Will this work for 7PRC with the GRAYBOE HUNTER M5 DBM - REMINGTON 700?

    yes it will but per MDT, you may need to bend the magazine feed lips open a hair for the 7mm PRC round to sit correctly in the magazine and feed.

  • Will the magpul aics LA mag work in your stocks?

    yes it will, though i have heard from customers that magpul mags can be finicky at times but if they are AICS style then yes they will work.

  • Does this AICS mag fit all your long action bottom plate grayboe DBM plate?

    This mag fits the long length M5 DBM's, not the CIP length.

  • Will this mag work for 7mm PRC in a Magpul stock

    yes it will but you may need to open the feed lips of the mag a bit for the rounds to sit high enough to be picked up by the bolt.
