This listing is for a solid aluminum Grey Anodized Dummy 12 Gram CO2 cartridge. This dummy CO2 has two 1/8" NPT ports, one on the end and one on the side .95" from the bottom. It is modeled after a real 12 gram CO2. The overall length is 3.25" and the diameter is .73" I have included one male 1/8" NPT plug so that you can plug the port you do not intend to use. The bottom port is commonly used with quick changers, and the side port is commonly used with pistols, where you drill through the grip, and run the remote that way. If you need the port to be higher than .95" from the bottom, please see my other listings, where I have one that is 1.5" from the bottom. This dummy CO2 is normally used to convert a stock class paintball gun or pistol, or BB/pellet gun or pistol into a constant air paintball or BB/Pellet gun, so that you don't have to keep buying and replacing those expensive 12 grams. It is best used with a paintball remote line. That is how I recommend using it. Please email if you have any questions.
I have been told by Ebay user "eastbaywarrior" that this side port height will work well on the following guns: Baikal Drozd, Beretta Px4 Storm, S&W M&P pistol, and Legends C96. It will most likely work well with many other guns. Let me know if you have a gun that this lower side port CO2 works well in, and I will add it to the list.
Don't risk drilling out and tapping one of your empties. That is HIGHLY dangerous. There will be less than 1/16th of an inch of threads, and your fitting is very likely to blow out, possibly causing injury. This Dummy CO2 has FULL LENGTH 1/8" NPT threads, so it is MUCH safer. If you are picky, depending on the type of fitting you thread into this dummy CO2, you may or may not have to tap the threads a little deeper to get your fitting to sit at the height you want it to when it is tightened. I have heard from some people that with some pistols, the small hole in the tip of this adapter needs to be partially drilled out to a slightly larger size so that it sits deeper into the valve body so that it seals.
These things are getting VERY hard to find in the last couple of years, so get yours before they are gone.
