PMag Blast Tube

A requirement for a PMag installation is the addition of a blast tube on the base to assist in keeping the unit cool. Since PMag does not sell an adapter, it forced me grab some scissors and create a template. It took little time and is very light weight.

Here is two orientations I needed for both of my PMag.

Here is a very easy design to cut and bend the adaptor which insures the air is directed into the cooling grill on the bottom side of the unit.

After bending the metal (.015” AL) a tube was riveted on and all was sealed with a bit of RTV.

Enjoy.
