It’s way too much. The value in this case is so high because it’s an old historic firearm.
With modern production capabilities you can buy brand new rifles for ~1000€ or handguns for a couple or 100€s. They just shoot as straight, if not better. Modern assault rifles cost around 1500-5000€s the last time I checked. Without full auto mode though, because they are illegal for civilians here in Germany (no civilian needs an assault rifle IMO). But technically/price wise I imagine the difference to be negligible between the two variants.
But some weapons from that period were masterpieces. Back then they had more or less only manually operated machines that needed a lot of experience and skill. A Mauser 98 for example can still be bought as a new weapon today. A century old design built today costs 10000€ upwards.
Thanks for waking memories! I had one of these. Highly modded, with a modchip, other OS and a large HDD for my game backups. I could also watch videos etc. Most fun I had with a console. This was the pinnacle IMHO. The next gen started with the enshittification process.
