KJW Spare Co2 Mag for 1911 Tactical / Hi-CAPA Series Airsoft Gas Blowback Guns

5 Customer Reviews

"Kyle, co2 magazines are for cold temperature and people that don't want to use green gas

The Hi-CAPA by WE and KJW can handle Co2 because the guns are full metal. The power outputof Co2 is only slightly higher than green gas's output power so the wear and tear concern you have may not be ultra great of a deal

On the other hand Hi-capa parts are very easy to find, sells everything you need to practically rebuild a gun cheap, unlike some brands such as Western Arms and KSC System 7. What I am trying to say is, the best way to prevent wear and tear is to not play...

"I fixed the leaks myself, DIY don't rma your product follow my advice. I had got two extra co2 magazines through buying and getting a gun (free epic bonus) both of which leaked bad out through the top of the magazine. Only one I could RMA because the other was past the date I bought it. I ended up ordering repair spare parts directly from KJ-Works waited a few weeks. I got a new value release because people told me when it leaks the top that is what causes the gun to leak. I installed the new value release and the gun still leaked. I tried my 3rd co2 magazine value release in the "broken" magazines, and it had no problems, I knew then it was something with my other value releases. I decided to order JB weld ultimate black after watching a few videos on advice to repair my gun magazine. The instant I turned the screw back on I was relived to find it had worked. JB WELD ULTIMATE BLACK IS THE ANSWER TO FIXING YOUR LEAKING MAGAZINES (THROUGH THE TOP)

I applied it on a good amount via the threads and the o-ring itself.
You will need a Gas Valve Key Tool for the job, I used other tools before but it stripped up my value and now it has a giant gap in it. The key tool is a must, $15 well worth it.

new magazine leaked
RMA "repaired" magazine leaked
KJ-Works direct OEM replacement value release leaked


No doubt it was a bad batch of magazine or all dried up, if you are buying this expect to repair this yourself. Now you can keep your magazine working for years with simple repairs.

4/5 stars, they need instructions on how to repair your own gear.

"Sure, this magazine is downright fun to use if you have a full-metal gun. It makes the KJW 1911 tactical kick like a .22, no lie! HOWEVER....I think that even still with the claimed "reinforced" parts, I think it had something to do with causing my gun to malfunction by putting stress on the parts.

Something all should note regardless, however, is that this magazine is guaranteed to blow on you eventually. The seal inside is not the best, and the co2 will eventually start blowing out the top immediately when a cartridge is pierced. I cannot confirm whether a new higher-quality valve can fix this or not. Evike even (in nice itty-bitty print) claims these magazines are unstable. So if you have your heart set on getting one, might as well have a better quality replacement valve just in case ;)

"This mag is pretty good when it decides to work.

At least twice now the CO2 cartridge has become stuck inside of the magazine and it refuses to come out. The only way that I have been able to remove it is with a hammer and a lot of forceful smashing I wish I didn't have to do.

Otherwise, the CO2 conservation is pretty great. It fires around 2 mags before having to be replaced and the CO2 retains much better than green gas. The kick and power that is added is also very pleasant.

Overall a good mag, but it just keeps getting stuck.
