I launched a detent ball for an obsolete 22 rifle, but found it 2 hours later, then promptly launched it again. Three days cleaning out boxes on some shelving, I found it. Those little balls can be a devil to find, luckily I was able to locate two used balls and some springs so I’d never have to repeat this again. It never hurts when the rifle performs flawlessly now.
I had one experience with FÃ customer support, and it was flawless. They replaced an Intellidropper free of charge and didn’t want the dead one back. Apparently they are different at different times. I’ll still use their products despite hearing about less than satisfactory outcomes that others have experienced.
