Rotary Delay Blowback Magazine Kit

Rotary Delay Blowback Magazine Kit

  • $325.00


This kit combines our Macon Armory 45ACP DI magazine well adapter with a 3 pack of our 20 round 45 Magazines (10 round will be substituted where required by law) and our thumb saving mag loader, for use with the CMMG Guard 45 ACP Rotary delay blowback upper. Installing in under 60 seconds, this kit allows the use of a CMMG Rotary Delay Blowback upper to be used on ANY standard AR15 lower with a mil-spec magwell....to include registered full auto lowers. As the guard barrel and extension and upper modifications bear a striking resemblance to the Macon Armory DI45 upper transferring from Glock to our mags is seamless and very reliable.

  • Retains use of standard mag catch.
  • Maintains last round bolt hold open functionality
  • Requires no modification to lower
