"Work as expected! Love them! The Co2 is easier to get than gas where I am from so I am glad Evike have these for my KWA!!!!
by Al L. on 10/17/2017
"I bought four mags, the first fired one round & blew all the c02 out on the second trigger pull. The second mag was returned with a c02 cartridge still stuck in it (never got to fire one shot). The second and third mags were repeats of the first. Needless to say I was highly disappointed. In short, don't waste the time, effort or the money. To many issues with this product, they need to get back to the drawing board ASAP.
Evike has been very responsive throughout this situation & I really thank them for that. Great customer service, BAD product.

Webmaster: Thank you for your support and we apologize for the inconvenience. Our supplier Palco had a batch of 12g Co2 cartridge that was too fat. We have since conducted quality control and going forward the cartridges will be standard size that will work perfectly with all Airsoft Co2 magazines.

"These look amazing. They work great. If you're using them in a green gas gun keep in mind you need to maintenance and oil your internals more because green gas is propane with a lubricant in it but c02 is just compressed air. The do feel just a little plasticy. Only reason for the 4.
