After buying a one-armed Strongarm from Sharky - to donate the spare arm to one of my sons' one-armed Strongarm - I was left with an armless Strongarm.
I also had a junker classics Bumblebee and mini KO Swindle gun... so I made this using Bumblebee's arms.

Seen here with my custom Blast Off.

Strangely, even though Strongarm is smaller than Bumblebee, his arm joints were bigger and had to be shaved down to accommodate the arms.

I also got holes drilled in Strongarm's right forearm and gun post so the gun can sit in them (thanks to my Mum's partner and his shed full of tools).

Regrettably, although Blast Off can combine with Energon Bruticus, Swindle can't... yet. I had ordered a combiner kit from Kidbash but I have given up hope of that arriving.
