so, the wood stock is OK, it's biodegradable and a renewable resource unlike the plastic one that will last forever in a landfill. Of course, the decomposition of the wood releases CO2 while any carbon in the plastic one would be entrapped or encapsulated or whatever the heck they think they can do with used CO2.

However, neither is capable of full automatic operation and as the saying goes, "Why waltz when you can rock and roll?".

Machetes are still legal though.
