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.

Frequently asked questions

Which magazines is this set for?

It is the O-ring set for Nuprol Raven EU series gas magazines (part RSP-02-03). It contains the assorted seal sizes needed to service that magazine family.

How do I know my O-rings need replacing?

The tell-tale sign is gas loss: the magazine hisses, empties quickly when stored, or will not build pressure to cycle the gun. Dry, brittle or split O-rings are the usual cause and this set renews them.

Can I fit them myself?

We recommend fitting by an experienced or qualified airsoft technician. Incorrect installation can cause leaks or damage not covered by warranty. If in doubt, our workshop can service the mag for you.

How do I keep the new seals healthy?

When storing a gas magazine, leave a small amount of approved airsoft gas in the reservoir. The gas carries lubricant that keeps the O-rings supple and prevents them drying out.

Is it worth repairing an old mag?

Yes. A set of O-rings costs a fraction of a new magazine, so resealing a leaky mag you already own is far more economical than replacing it.
