This is a replacement buffer plug for the AR CMMG .22 conversion bolt carrier group.

This completely replaces the original AR15 buffer plug and does not require additional topper.

The plug will push the BCG forward preventing it from sliding and it's profiled for easy open and close of the upper receiver.

Printed in PLA+ tested for several months with no deterioration noticed.

I advise running adaptive layer in the slicer for best results.

No supports needed.
