A friend of mine stuffed his 47 full of Twinkies. Like, multiple jammed in the receiver, and stuffed into the cover, a bunch smeared all over the spring, just stuffed it with Twinkies. It still fired... Lol. All it took was firing a few magazines and it was fully functional again. They're great, durable weapons.
I'd never do the Twinkie test to mine, I love it too much lol. I've got a Romanian 47 with a folding stock and a Russian Kobra reflex sight. The sight pretty much cost the same as the gun itself but it was very worth it, since it's so durable. Plus it's fun to use
