Blackadder's OCD:
I wouldn't be the Blackadder if I didn't try to improve on the model in question. Since the legs and feet are too small and weak to try to articulate them I settled for the arms and armament. I have three weapons for the Decimator; a big cannon like drum weapon, a Butcher Cannon and a multiple barrel whatever ah machine gun I guess. Anyway I wanted them to be interchangeable and I also wanted the to be pose-able in their elbow sockets and I wanted the arms shoulders to move as well.

The tools seen here and the neodymium magnets are what I used to attach the weapons by drilling the magnet diameter holes and supergluing the 3mm disks in the elbow joints and mount tabs on the weapons
The shoulder flexibility is achieved by drilling and tapping 6-32 threads in the resin and securing with 6-32 screws.

You can readily see the move-ability of the shoulder in the above image.

Because the weapons are magnet mounted changing them requires but an instant.
