Just a note, the AG has a rubber doughnut on that rod on the bolt cover. If missing, the rod will ding the cases. I think Numrich may strill have that part.
There WAS an Armourers' kit with "washers" in varying sizs, pus the special tools for changing them. Trouble is that none of these kits and tools made it to this side of the Great Puddle.
The Danes, on their Madsen-Ljungman, tried to slow the gas down a bit by wrappng the gas tube around the barrel. The Egyptians did it the right way, by introducing a proper gas regulator.
Problem is that the rifles were expected to function properly in a Swedish winter, which isn't all that much nicer than a Western Canadian winter: it gets COLD.To compensate for this, they set the things so they would be SURE to cycle, even in -35C and worse. This made the cycling more than "a bit brisk" when the temp was ABOVE -35C.
Add to this the fact that almost ALL military ammo is loaded with very fast powders: less tonnage for transport, less $$$ to make. Swedish military powder for this round is roughly in the 3031 class. Anything slower will give higher-than-normal pressures at the gas port.... meaning faster and harder cycling, which includes ripping off rims and throwing the brass to the other side of Hudson's Bay.
Best bet is to install a gas adjustment.... and then use it.
