A cello (or any hollow piece of wood hollow enough to function as an instrument) would make an absolutely abysmal stock, especially for what appears to be an AK47 or an RPK. The majority of AK47s fire a 7.62x39mm cartridge, which, upon firing, would crack the wood easily. Also, a gun that’s part cello, if it somehow didn’t break, would be far too impractical to aim.
