Norwegian soldiers having problems with HK416

Tanfo, a Norwegian soldier, reports at the forum that they have been having problems with their new HK416 rifles.

Norwegian configured HK416 with suppressor.

One of the problems is that the piston system locks up if the gun is taken outdoors from a warm building when the humidity in the air freezes in the Norwegian arctic conditions. The C8 (Colt Canada full-auto AR-15) that is used by the Norwegian special forces also has this problem but can be fixed in a much more timely manner than the HK416.

Apparently the gas regulator, which that controls the amount of gas flowing into the gas piston system, often switches modes during firing. The gun will not function properly if set to the suppressor mode if a suppressor is not being used.

I imagine the Norwegian will have these problems sorted out in the next few years. It does seem odd that they did not identify the problems before purchasing the rifles.

Many thanks to Jay for the link.

    The Norwegian Army is now considering to change back to the normal lead based ammo.

    This is an old argument. I heard it a lot from some of the Vietnam Vets when i was in the Army in the 80s ...Their point was a weapon made for grunts to be used under field conditions cannot be that sensitive to conditions. A grunts weapon has to be rugged and grunt proof. You can't tell a grunt he has to be perfect in field conditions. I have seen a lot about this weapon on television and it seems like a great concept and if its an HK it must be well engineered and I might add that I would love to have one but if these concerns are true it is an issue that has to be addressed
