I’ve been in a similar situation, trying to fit more long guns into my safe without scratching or damaging them. I tried a few different racks, but none were as effective as the rotating design you described. I actually ended up using a similar setup in my Liberty safe, which made a huge difference in how easy it is to access my rifles without messing with the rest of the storage. I also use gun socks and some padding, like you mentioned, to protect the finishes. I’d definitely recommend looking into
most trusted gun safes like Liberty if you’re after something durable and secure.
