NAA's web site says that there will be a FOUR INCH BARREL version made for the California market - so that might be good news for the possibility of exports to NZ.
The 'break-open' design goes way-back into time and is a very logical and convenient system to use. It seemed to go out of fashion when hotter larger cartridges developed and these more powerful rounds tested the designs hinge & latch strength beyond the early guns metal strength .. but I've always felt that issue shouldn't be an issue 😇 when using the current metallurgy and better design features.

The five shot Ranger 2 may well be a *HIT* with 'merican' shooters,
