Army armament combat master r601 mods

[HolmesL123]

I recently bought a second hand AA Combat master and am unsure of its modding compatability and what stock to use. I have heard different things from different places about it's TM compatability and hop unit and so figured I could ask here. Much thanks.

Mine runs a maple leaf crazy jet barrel and M/L rubber. Cant remember off the top of my head if I also fitted an I key to it. Performs very well.

For me stock performance has been good, just give it a good service. Also check the hammers condition, if it looks well worn replace it for peace of mind as they are a known weak point.
