The Steyr-Mannlicher rifles would be cool as a K98 replacement, as the M95/30 was a 8x56R conversion of existing M95 Stutzens in 8x50R. They were issued beginning c. 1931 and continued in service until 1940.

Any custom models would be great. Not saying the defaults aren't good, I just like a little variety. I'd love to have another K98 model made, but that's just me. Seems like a good idea engineer, just need someone to model it and someone else to skin it I suppose.
