Raven EU hammer and spring

This is a replacement hammer and spring assembly for the Raven EU series of gas blowback airsoft pistols, the Glock-style platform. Nuprol references it as EU series part RSP-07-01, so it is a direct factory spare.

What it does

The hammer strikes the magazine valve on each trigger pull to release a metered charge of gas. The spring sets how firmly it hits, which directly affects consistent gas release and shot-to-shot behaviour.

When to replace it

A tired hammer spring causes light strikes, misfires and weak, inconsistent gas release. Fitting a fresh hammer and spring restores a crisp, reliable strike and steadier performance.

Fitting and support

Access means opening the frame internals, so it suits a full service or rebuild. If you would rather not strip the pistol, our technicians can fit and test it through our airsoft gun repair service in Kent. Find more spares in our airsoft accessories range.

Frequently asked questions

Which pistols does this fit?

It fits the Raven EU series of gas blowback pistols, the Glock-style platform, and is the factory hammer and spring assembly for that frame.

What problem does it fix?

A worn or weak hammer spring causes light strikes on the magazine valve, which shows up as misfires, weak gas release and inconsistent shots. This assembly restores a firm, reliable strike.

What is included?

It is supplied as a hammer and spring assembly, referenced by Nuprol as RSP-07-01, so you get the parts needed to restore the striking function.

Do I need any special tools?

Access means stripping the frame internals, so a basic pin punch set and some GBB experience help. If in doubt, have it fitted professionally.

Can you fit it for me?

Yes. Our in-house team can carry out the strip, fit and function test through our Kent repair service.
