I am the same as you onetrack normally.
Unless I need 50cm worth of thin drift into confined space as a rear differential on a landy if you managed to get at it just after it was seized with that you could knock the diff lock out and run the thing with the rear prop shaft detached in front wheel drive only.
I honestly don't think you will shatter this thing, its quite unlike any bit of metal I have come across. Its the piston which drives the working parts forward in a high velocity semi automatic rifle with the pressure across a 10mm piston. And it doesn't shatter when the breach jams shut and the working parts stay forward with the gas plug blocked. This does result in the poor sod that pulled the trigger going to hospital though with shattered sinuses and a broken collar bone.
I have seen them belted with a sledge hammer, metal on metal by a 105kg Fijian using it like a war hammer as they do. I might add the tank power pack remained well and truly
ed after he had finished with it.
Some had the piston off a GIMPY which is even meatier and longer.
