Stop the leak, save the magazine
Gas magazines live and die by their seals. When the O-rings dry out, harden or split, the mag hisses, loses pressure and eventually will not cycle the gun. This Nuprol set (part RSP-02-03) supplies the assorted O-rings needed to reseal a Raven EU series magazine and bring it back to full working order.
A complete service in one packet
Rather than hunting for individual seals, the set gives you the range of O-ring sizes the magazine uses, so you can refresh the whole gas system in one go and get a reliable seal that holds pressure again.
Repair rather than replace
Do not bin a leaky mag. A pack of O-rings costs a fraction of a new gas magazine, so resealing the ones you own is the smart, economical choice, and better for keeping a matched set of mags running.
Fit it right, keep it healthy
We recommend fitting by an experienced tech, and our Kent workshop can do it for you. Afterwards, store the mag with a little gas in it to keep the seals supple, and browse more airsoft spares.
