Aluminum CO2 Paintball Tank

Durable, easy to use. I haven’t noticed any leaks.

There is not much to say, this CO2 tank does the job. Recieved and filled two of them today (01/21/13), after I got home I plced them in a bucket of water to check for leaks, both did leak from the rupture valve threads, one was releasing one bubble every two or three seconds, and the other one was releasing about a bubble every five minutes. I took a 10 mm wrench and tightened up the rupture valve a little, there was a slight give before rupture valve came to a stop, after that leaking completly stopped. So my suggestion would be to tighten the rupture valve before filling and you will not loose any CO2. Shipping and packaging was superb as usual from amazon. Thanks for awesome pricing!!!

I got this to use with my aquarium CO2 system and it works very well. I didn't need a lot of CO2 and this is much smaller than a 5lb tank and works quite well with one of the adapters that are available ( AQUATEK CO2 Paintball Tank CGA 320 Adapter ). Even if you are using it for paintball and don't have anyone that can fill these cylinders get the adapter and they will be able to easily fill it once they figure out how the adapter works. It did come with a cap to protect the threads and pin valve. And wrapped in bubble wrap. Be sure to take the adapter with you when you get the tank filled if you get it filled by a company that doesn't normally fill paint ball cylinders. Finding a someone to fill the tank in my area was my only challenge. I'll be ordering a 2nd one for a spare for when my existing tank empties.

I now use this CO2 tank for my planted tank setup as they need it to flowrish. It does what it supposed to. Holds the air in and it lasts me around 2 months before a refill. If using for paintball CO2 lasts longer than HPA, but is more expensive to refill. Also, it can mess up your gun if you don't use it properly. The number of shots you will get with this varies from gun to gun. For most Spyders and clones that accept CO2, you will get about 1000 shots out of a 20 oz, and about 800 from a 16 oz. This is how many good shots you can get out of them, not how many times it can possibly be fired. You can get more than quoted above out of these tanks, but they curve and don't go as far when low on fill. I have never owned a 9, 12, or 24 oz. cylinder, so I can't account for how many shots they hold. If you are trying to compare a shot count from CO2 to HPA, it's rather easy. With a 3000 PSI HPA system, you'll get 10 shots per cubic inch. With a 4500 PSI system, you'll get 15 per cubic inch. HPA is good for the whole tank - it doesn't decrease in performance until about the last 50 shots. CO2 tanks are all fillable to a maximum of 1800 PSI. All CO2 tanks are fillable this high. You don't have to worry about this factor with CO2, just HPA. There is a large scientific study to be performed about the consistancy of CO2, but I'll keep it short. Just get a remote or anti-siphon tube, and it'll be a whole lot more consistent. Trust me.

I got this CO2 tank couple days ago 11-22-10 and I was if'y about actually buying it offline but I got it in the mail it said paintball on it in decent size box for it. It came to my door but I wasn't home so I had pick it up at my local mail office. It was not filled when I got it so I took it to Dick's Sporting Goods and got it filled for about $4.00 and I haven't used it yet but so far so good. It don't l0ok exactly like the picture but it looks clean snd decent..So, far it was worth it and I will be buying at least two more next time I get paid. If you are looking for a cheap CO2 tank espically a 20 Oz then buy it off of here! You won't regret it and if you do you can always send it back.. lol..

I bought two of these to use with a beer regulator/adapter. Built my own keg cleaner for Sankey style 5 gallon kegs and wanted an easy portable C02 supply to pressurize them. These work great and they are perfect for if I want do a keg for an event. Why mess with those crappy hand pumps when you can 'set it and forget it' with this. Not the most value oriented size, cost about $10 each to fill at the local welding shop where I get my bigger gas bottles but since these are for special purposes I don't expect to have them filled a lot. The adapter for attaching these to a regulator is under $20 so if you have a kegerator or doing anything with regulated C02 gas this is a very handy thing to have on hand.

Because of the great price, I bought 2 of these tanks. When they arrived, I filled them both for $5 each. After about 2 months, one of the tanks was completely empty. I had the shop check the valves and all looked ok. So, I filled the tank that leaked again. Sure enough, after about a week, it was empty again. I tried to return the defective tank, but since it is not an "Amazon Product", there is no guarantee that it will be replaced or refunded. I mailed the tank back to Amazon as instructed on their website. A few months later, I have not heard anything, so I expect it is just a loss. Bottom Line: I really ended up paying double the cost (since one tank was bad), then spent $10 for two fill-ups and then spent $7 to ship the item back; without any replacement. When you add that all up, I really spent a lot of money for one good tank. I know that is the risk of buying online, and I buy a TON of stuff online. I feel it is my responsibility to let others know when a purchase goes bad, so that they can avoid the same issue. Buyer Beware! Update 10/19/2012: In fairness to Amazon, I did receive a refund for the bad tank. Thank you Amazon! But, I'm still out the return shipping cost and two tank fill-ups.

I bought this to use with my Fluval System, using an adapter, it works perfectly

A complete waste of a purchase! The bottle is empty! It is not advised as that… but very cleverly advised as a Co2 20oz paintball bottle. Pissed off!

seems to work just fine - decent price

thought this would be the smaller Guerrilla style tanks but still fits my Rap4 T68 paintball gun but without the stock attached, also it's 1800psi as opposed to the more expensive 3000psi version which could be mentioned on the item page with afew other technical specs otherwise full 5 stars, still plenty of shots and lighter, seems like good solid build.

Good quality Half the price as in store. Thank you!
