Basically it's just using pure silicone spray to lube them up. It's a good band-aid, but never recommended to use over and over. Lubing too much can collect dirt, and here in AZ that will be inevitable anyways.
Basically, get some silicone spray, and spray a few small shots in the hole you load your BBs into. I'd, personally, only recommend it if you needed to make a quick fix if your mags jammed in the field due to dirt.
