The NM149S was developed in close cooperation with the Norwegian Army and is based on the tried and true M98 bolt action. The stock is adjustable for length of pull via a spacer system, and the barrel is of heavy contour and the system shoots very well. There was a problem with the early versions with the stock cracking, but that problem has since been solved. The system is very capable and effective and has been serving in the Norwegian army since at least 1988, some reports indicate perhaps as early as 1986.
An improved model, the NM149S-F1, has since been developed and produced. It has a better and stronger laminated stock, a permanent front sight, and a flash hider. But the stock is not pillar bedded, and is more suseptable to changes in weather.
Thanks to Svein and others for the info on this rifle!
If you have some photos for us to use, we would appreciate any help.
