I've owned numerous Steyr-Mannlichers, all with synthetic trigger guards and magazines. I have yet to own one where that bottom plastic didn't crack. The all-synthetic versions were the worst because the stocks themselves would crack, usually right near the bolt handle, where the stock is thinnest. The magazines were advertised as unbreakable and that may be true when empty, but when loaded, heavy with lead, if dropped on a hard surface they could explode, usually breaking in the corners where there are the tiny screws that are necessary to hold the mag together.
I have had only one old one trigger guard that didnt show some cracking at almost 40years, but replaced mine with the new moldings since at 80$s it seemed cheap. Lots of options today though, AICS adapters, new Steyr plastic ones, reinforcement adapters, and several aluminum replacements ...Again newer ones are made of better materials, so worth getting if available, compared to older ones.
None of this helps the owners of the Cycolac plastic-stocked "Professional" Model of the Steyr-Mannlicher....sooner or later they crack right through the the stock right at the weakest (thinnest) point near the cut-out for the bolt handle.
True, but replacement stocks can be had. Sucks, not cheap, but replaceable.
Are the "replacement stocks" just NOS or are they made from new and better material?
There are new material ones from steyr, several companies making synthetic stocks, laminated ones and aluminum chassis out there.
There is an army and navy mannlicher 9.5x57 at the upcoming switzers auction, apparently it has a mirror bore. If I had the money...

Wildcat composites in Edmonton makes a replacment from fiberglass/carbon fiber.

This is a short-action 8x51 which may help explain the high ($3,500 US) starting bid and the estimated value ($7,000-12,000 US)...yet it is disfigured with nearly useless claw mount bases.
I'll be interested to see what it goes for...
A couple of years ago, there was a short-action Oberndorf Mauser Type S for sale locally. It had a non-original bolt handle and was drilled and tapped for a scope. And as I recall the dealer was asking around $5000 (Can)
Note the hollow bolt handle knob on the auction rifle.
