No, I'm not suggesting refilling 1lb Coleman bottles. I hate the idea of wasting and adding unnecessarily to landfills let alone paying more than I have to for something. Using the Coleman bottles was just barely OK when I only needed occasional fills for my pistol mags, but when I got my new KJW M4 gbbr I figured there had to be a better way...
I bought a 5lb refillable propane tank and a 5' propane hose with a propane fill nozzle. The tank is fillable wherever you buy propane and is easy to carry around and turn upside down. Whenever I want to fill my mags, I open the valve, flip the tank upside down and with the convenience of the hose can easily manipulate my mags and fill nozzle.
The tank costs $50, which is basically the same cost as a 10lb or 20lb tank, but in my opinion, a lot more convenient to transport and use. The cost of the propane that goes in it is the same, so it's up to you what size you are most comfortable using.
There is a bit of an investment: Manchester 4.9lb OPD barbecue tank- $50, Mr. Heater propane hose 5 ft. - $30, (both from Canadian Tire) Madbull propane adapter $25 (which you either have or have to buy anyway) but once setup, you are paying about $0.85/lb of propane instead of $4.66/lb, a saving of around 82%. For those keeping score at home, the break even is about 21 lbs or 7 of the Coleman 3-packs. To be honest, I have no idea how much gas I'm going to go through, but it's mainly for the principle of it all. Maybe someone will be able to find a source for a cheaper tank and hose and make it even a better deal.
Anyway, thought I'd pass this on to the community...
