In 55 years of military, hunting, and sport shooting??
I can't think of a single time I needed to oil a weapon bad enough to wear a bracelet full of oil all the time.
Military weapons usually had a little oil bottle it the stock cleaning kit.
Or in a cleaning kit pouch you wore on your web gear.
Hunting and sport shooting?
My sporting guns are clean & oiled before I leave home, and I have never in my life needed to oil them again in the field.
If going on extended hunting trip far from home, I take a normal cleaning kit in the truck with me.
So I would have 0 interest in something like that.
