Madbull CO2 Filler with Pressure Gauge

"This is a MUST HAVE for anyone with CO2 compatible weapons and accessories. The adjustable PSI is what really makes this the best pressurized gas delivery system out there.

"I bought this and it works great, you can regulate the pressures so you can turn down the pressure to fill guns/grenades that can't handle co2. But there is one thing I noticed and It wasn't mentioned in the details when I purchased it is the fact that if you take the hex part off (where the co2 cylinder goes in) you can put this on large co2 tanks (like the ones used for paintball) so you dont need to constantly buy the little 12gram cylinders.

"This charger works great! The co2 gives my grenades more power than when using propane.
By the way Brad H. Green gas is the samething as propane but with added lubricants. Co2 Is MUCH more powerful than propane/greengas although close to red gas. You should not use this charger to use in your green gas/propane/ 134a(white gas) guns. It will obliterate your gun. it WILL break. All in all a great and handy piece of eqiptment
