Airsoft Pistol Loading Nozzles & Nozzle Springs

The loading nozzle is the moving part that pushes each BB into the hop-up and directs gas to fire it, before the blowback cycle resets it. A cracked nozzle or tired return spring causes misfeeds, weak blowback and gas leaks.

Our airsoft loading nozzles, nozzle return springs and short stroke kits suit the AAP-01, Hi-Capa, Umarex Glock and MK23, with upgrades from Cow Cow, TTI, Hadron, Pro-Arms and Tridos.

Frequently Asked Questions

Need To know more?

What does a loading nozzle do?

It pushes each BB into the hop-up and directs gas to fire it. The blowback cycle then resets it ready for the next shot.

What do the percentages on nozzle springs mean?

They show the spring's strength compared with the stock spring. A 150% spring is 50% stronger, helping the nozzle return fully for better feeding.

What is a short stroke kit?

It shortens the slide's travel for a faster cycle and higher rate of fire, mainly on full-auto pistols like the AAP-01.

How do I know my nozzle needs replacing?

Common signs are misfeeds, double-feeding, weak blowback or gas leaking from the slide. Check the nozzle for cracks.

Loading Nozzles

Upgraded nozzles are tougher and seal better than stock parts. Popular choices include the Cow Cow AAP-01 aluminium nozzle, the Cow Cow enhanced loading nozzle set for AAP-01 and the Cow Cow enhanced Hi-Capa nozzle set. For WE pistols, browse our genuine WE spare parts.

Nozzle Return Springs

The nozzle return spring pulls the nozzle forward after each shot. A stronger spring helps the nozzle return fully, improving feeding, especially on full auto or with stronger gas. Choose from the Cow Cow AAP-01 200% spring, Pro-Arms AAP-01 130% spring, Tridos AAP-01 spring set or, for Hi-Capas, the Cow Cow NP1 180% spring and Unicorn Hi-Capa spring set. Umarex Glock owners can fit the Pro-Arms 130% nozzle spring, and MK23 owners the Tridos SSX23/MK23 nozzle spring.

Short Stroke Kits

A short stroke kit shortens the slide's travel, giving a faster, snappier cycle and a higher rate of fire on full-auto pistols such as the AAP-01. Try the TTI AAP-01 CNC short stroke kit or the Hadron short stroke buffer with 300% nozzle spring.
