Restore crisp, reliable cycling

The nozzle return spring is a small part with a big job. Every time your Raven 1911 or MEU cycles, this spring returns the nozzle assembly forward so the next BB chambers and feeds correctly. It is listed as part number 11 on the exploded diagram, and like any spring it fatigues over time.

Fix short stroking and weak action

When the return spring weakens you will notice the slide failing to return fully, short stroking, misfeeds or a generally sluggish action, especially in colder weather. Swapping in a fresh spring is one of the cheapest ways to bring a tired gas blowback back to snappy, dependable performance.

Correct fitment

This is the genuine replacement for the Nuprol Raven 1911 and MEU gas blowback pistol series, so you get the right rate and dimensions rather than a generic guess.

Fitting and servicing

Accessing the nozzle assembly means stripping the slide, and incorrect reassembly can cause damage that is not covered by warranty. We recommend an experienced or qualified technician. Our Kent airsoft repair and servicing team can fit it for you, and you can find more internal spares in our airsoft accessories range.
