Airsoft CO2 Charger 12g with Silicone Port

got it to work 2 times but it froze the o ring "if you can even call it that" and tore causing it to leak and the puncture nozzle got dull and wouldn't pierce the foil top of the co2 capsule. just get a more expensive one that has a gauge on it

Got this to fill my Avengers 40mm airsoft shower shells with CO2. Works fine, but if you lose the piercer seal you are out of luck - nobody sells it. Mine blew off at some point and went to the moon. So I designed a printable TPU seal that's worked fine since.It's a bit tough to tighten down and pierce the 12g on some brands of 12g caplet, due to varying seal thicknesses. I use Umarex, which are pretty thin, so I've had no problems, but I'm really big with a lot of grip strength. Your mileage may vary.

You have to use pliers to get it to close enough to pierce the cartridge, the catridge doesn't pierce enough to fill even the smallest resevoirs (shotgun shells) with high pressure, green gas gives me a much higher FPS even though it shouldn't. And the rubber gasket fell out after 2 cartrides. Not a well designed product. Look elsewhere.

Get you gasket and casket it goes immediately
