15 round clip (vs the standard 10)?
Oh no, this is CANADIANS [er, les Canadiens!] we're talking about here.
The chemical composition of the vinyl was *tweaked* with charcoal-based carbon content and nitrates so that the little plastic stripper clips were also usable as wet-weather fire starters.
I don't know if this applies to the ones made in North Carolina and sold in the USA, but a few decades back when I took an Alaskan USAF winter survival course, this was demonstrated with a couple of the *plastic sticks*.
Also unknown: if the charger guides or magazines themselves were ever made of the same composition. But y'know, the magazine floorplates could indeed be a mechanism for igniting sparks...if they were made of carbon steel instead of aluminum.
