I have decided to make new compression plugs as opposed to forking out for new AA units assuming they are available.

I have no idea how long this project is going to take me due to other commitments, but I have made a start. Double click on an image to enlarge.


I'm currently thinking about which method to use to seal the barrel in the breech, favorite at present is to machine a groove into the rear of the compression tube plug to take an "O" ring of 2mm section.
I did contemplate using Pur90 but think I will use NBR70 if I go this route.

Okay then mick
