Renowned for their reliability, can a month underground improve the luster of a decent Kalashnikov? To find out, Brandon Herrera dug a hole Goodfellas style and interred one slightly used AK47 of his own design, then came back and brought it back to the surface.
Now Herrera doesn’t seem to do much prep other than just dropping it in the hole unsupervised. He doesn’t even wrap it in a garbage bag. All in all, although the wood is kinda grungy, it seems to work better than some brand-new domestic builds right out of the box.
The tale is not surprising as CJ Chivers, in his book on the AK, mentions anecdotal interviews with African militiamen who stashed Kalash for months or even years at a time in everything from caves to termite hills and went back to find them none the worse for wear — except that the stocks were trashed.
If you dig the above, Coyote Works, a desert and wilderness survival channel on YouTube, planted a Ruger 10/22 in the earth for about 15 months then went back to see if it sprouted.
