Maybe it’s early to start drinking, but it’s not too early to start planning. And in this case, it means pulling out the ol’ SKS. I cannot fathom of a more appropriate rifle to use as a bottle opener. Yeah, I know what you’re thinking, Mosin, duh, but who has arms that long?
The gas is clearly just blowing the bottle caps off, and that hole looks like still-burning gas just flashed right through the soft steel. I wonder if this works with rifles that have muzzle devices attached; will this technique work using a flash hider? What happens if you use a honking muzzle break?
Can a handgun do this, and if so, what caliber?
Clearly more research is necessary.
