So I'm upgrading my army a bit and wish to replace the bolt-action rifles already in use (convert a few to sniper rifles and give the rest to militia units), so I'm looking at a semi-automatic rifle for my frontline units.

I have two coniditions;

1. Since I'm in Mac's Fedala Accord I would like the rifle to be able to use 6.5 x 45mm rounds.

2. I'm a largely WW2-era tech based nation and so the rifle must be able to be produced with tech that was around in 1940.

you could base it on this rifle http://en.wikipedia.org/wiki/Ag_m/42

Modified Garand go go go!

Or, hell, the SKS, but I never got to shoot that one. One of my gun-collector friends speaks glowingly of it, though.

Here's one of my designs from the late fifties.
