Works exactly as intended, but... - FAB Defense QR Picatinny Shotgun Shell Holder

Seems to be well made and holds shells firmly. Not sure why another reviewer commented that this shotgun shell holder could not be mounted upside down. He claimed the shells fell out. I call BS. No way shells would come out unless you’re slamming your shotgun against a rock like a sledgehammer! The shells fit snuggly; tight enough that there’s no way they fall out by accident but not so tight that they’re hard to extract when reloading. My only gripe is that the quick-disconnect is a little quirky. Even after flipping the QD to OPEN, you’ll have to loosen the nut to get the holder onto a rail. If you loosen too much, when you flip the QD to LOCK it wiggles a little. You’ll need to play with the adjustment a bit. Even after you find a balance, it won’t be easy to just flip the QD to OPEN or LOCK and take the holder off or put it on the rail. IMO - a minor inconvenience.
