"Got some for my double eagle rebranded jag arms shotgun(they are known for the leaky gas tank in the full stock) and it works flawlessly now. Also if u want to a cheap, reliable, gas 3/6 shot shotgun, then check out the de rebrand of the jag arms scatter gun.

"So i bought these for my KWA VZ61 and the extended mags also the short mag would leave 5-10 bbs left in mag and run out of gas. At first i thought itvwas the mags bc i read reviews about the extendeds not able to hold enough gas. So i took the orings out and all mags worked great even held extra gas. The orings dont work with KWA VZ61 so dont buy for them, i like the orings seem solid and work with other guns 5 stars on the orings jus dont work with KWA VZ61 mags.
