.45ACP Magazine Well Adapter Kit

  • $349.99


Our Macon Armory magazine well adapter features a bottom-load adapter made from anodized 6061-T6 aluminum with hardened steel bolt catch actuator and feed ramp, 3 of our steel black nitride finished magazines , and mag loader .

This kit combines our Macon Armory 45ACP DI or Blowback 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 or standard blow back uppers offered by numerous manufacturers. 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

Available for either Blowback or Direct Impingement/RDB uppers, our "magwell" adapter kit is designed to work reliably with our  .45ACP uppers and takes just moments to install in a standard AR-15 lower receiver mil-spec magazine well.
Compatible ONLY with the Macon Armory Magazine.

MOST Blowback uppers available from other sources will work with our system, but if you have issues, contact us and we can usually solve by correcting feed cone geometry and converting the bolt to a controlled feed configuration. If you want the best 45 experience possible, then check out our complete 45 conversion kits that combine this kit with one of our superior uppers.
