WARNING: If you ever come across these... DO NOT BUY THEM
I bought 3 of these bottles. Look very closely at the second pic I took. You can see a tiny little chunk of a rough spot. Don't know exactly why that's there but probably has to do with how they were made.
I own a S&W 40F gun and these BBs continuesly get jammed in the mag because those little spots on the BBs simply won't let the BBs through. Baaad BBs.
