Here is my Ljumgmann AG 42B:

The Ljungmann is Swedish, and began production in 1942. It is chambered in 6.5*55 Swedish Mauser. Some minor defects were noted in the original design, so they underwent what is known as the "B" conversion in the '50's (I think). An original, non converted AG 42 is rare, whereas the B guns are fairly common. They were imported in quantity about 5 years ago, when I got the one in the photo above. I believe that the only reason it was successful is because the Swedes had the luxury of having good ammo. Had this thing fired the dirty stuff like the Soviets used, it would have been a poor performer.
The MAS 44 was the French direct system. This was one tough rifle, and was quite reliable. The reason it was reliable is that it was made to loose enough tolerances not be effected by fouling in the action. Unlike the AG 42, this rifle saw combat in Africa, and performed well.
Alas, darwinisim took place, and this system is now dead. The other methods are indeed superior. After using the AG 42, I tend to agree!
The AUG is piston driven!
