Ljungman Updates: the AG-42 vs AG-42B

In 1953, the Swedish military launched a program to refurbish and refit all of the Ag m/42 rifles in inventory. Aside from replacing broken parts and worn barrels, the program also made a number of improvements to the rifles:

* Auxiliary front magazine catch added
* Large gripping lugs added to bolt cover
* Rubber case deflector added
* Single-piece cleaning rod to replace the two-part original
* Rear sight geometry modified
* Rear sight range dial modified
* Dual-wire recoil spring in place of the original single wire type

These updates were made to virtually all rifles then in existence, and it is very rare to find original pattern Ag m/42 rifles today.
