The HRD GEAR 6mm magazine spacer kit is designed to make the popular 6BR case and it's variant cases run flawlessly in the AW/AX magazines (part numbers 0726 and 6677).

The back spacer is a press fit and clips into place from the top of the mag.

There is a small hole to aid in removal of the back spacer (the tip of a bullet fits perfectly). THERE ARE NO TOOLS OR MODIFICATIONS NEEDED OR REQUIRED TO INSTALL THIS SPACER KIT. 

Tuning of the Magzine feed lips may be required for consistent operation.
