Airsoft Nozzle Finder
A nozzle means a different part on every powerplant, so the first step is knowing which type your gun uses. AEGs use an air nozzle that fits by length in millimetres, gas pistols use a platform-matched loading nozzle, gas blowback rifles use a brand-proprietary nozzle, and HPA guns use an engine nozzle. Match your gun to one of the four types below, read the correct fitment for your exact platform, then compare every compatible nozzle we track with prices across retailers. We cover 5,230 nozzles across AEGs, gas pistols, gas rifles and HPA engines.
AEG Air Nozzles
An AEG air nozzle sits on the cylinder head and pushes air behind the BB, and it fits your gun by LENGTH in millimetres. Length is platform-specific: an M4 uses roughly 21.4mm, an AK around 19.6mm, a G36 about 24.5mm, and larger platforms like the SCAR-H or SR25 are longer again. The right length gives a clean air seal and reliable feeding, so match the length to your gearbox and platform first. Adjustable-length nozzles (Maxx, Perun) exist to fine-tune air seal and feeding when a fixed length is between sizes.
Gas Pistol (GBB) Loading Nozzles
A gas pistol loading nozzle routes gas to launch the BB and cycle the slide, and it is platform-specific. The good news is the two biggest families cross over: Tokyo Marui-spec Hi-Capa and 1911 pistols share the same loading-nozzle architecture, so many parts interchange between them. Glock-pattern pistols are a distinct design and do not share the Hi-Capa / 1911 nozzle. Elite Force and other proprietary 1911s can differ too, so always confirm your gun is TM-spec before assuming a fit.
Gas Blowback Rifle (GBBR) Nozzles
A gas blowback rifle nozzle is strongly brand-proprietary. The Tokyo Marui MWS, WE, GHK and VFC gas rifle systems each use their own nozzle, and they are not interchangeable across brands. Even different generations within one brand can differ, so a VFC Gen 3 nozzle is not the same as an earlier VFC part. Adjustable NPAS (Negative Pressure Air System) nozzles, such as those from RA-TECH, are made per brand to let you tune power, so match both the brand and the exact system before buying.
HPA Engine Nozzles
An HPA (High Pressure Air) nozzle is part of the HPA engine, not the gearbox, and it is engine-specific. PolarStar (Fusion Engine, JACK, Kythera), Wolverine (INFERNO, HYDRA, MTW), and other HPA engines each use their own nozzle sized for that engine and often for the gun platform it is installed in. Match the nozzle to your engine first, then to the platform length where the engine offers different nozzle sizes.
What nozzle fits my gun?
| Your gun | Nozzle type |
|---|---|
| M4 / AR-15, AK, MP5, G36, SCAR, P90 AEG (electric) | AEG |
| Hi-Capa or 1911 gas pistol (GBB) | Gas Pistol |
| Glock-pattern gas pistol (GBB) | Gas Pistol |
| TM MWS, WE, GHK, VFC gas blowback rifle (GBBR) | GBBR |
| PolarStar, Wolverine or other HPA engine | HPA |

Why AEG nozzle length matters
On an AEG the nozzle fits by length in millimetres, and the correct length is platform-specific. The nozzle has two jobs: seal against the cylinder head so no air is lost, and chamber the next BB cleanly. Too short and it under-seals, costing FPS and consistency. Too long and it pushes into the hop-up and causes feeding jams or double-feeds. An M4 is around 21.4mm, an AK around 19.6mm and a G36 around 24.5mm, but these are starting points: the reliable method is to measure the nozzle you are replacing and match that length. The AEG page carries a full length-by-gun table and covers adjustable and bore-up nozzles.
Nozzle or valve? Read the title
On gas pistols and gas rifles, retailers often group loading nozzles in the same category as fill valves, output valves and knocker valves. These pages filter to the nozzles, but a nozzle and a valve are different parts. When you buy, read the product title to confirm you are getting the nozzle you need rather than a valve.
Frequently asked questions
How do I know which nozzle fits my gun?
Start with your powerplant, because a nozzle means a different part on each. An AEG uses an air nozzle that fits by length in millimetres and is platform-specific. A gas pistol uses a loading nozzle matched to its platform (Hi-Capa and 1911 cross over, Glock is distinct). A gas blowback rifle uses a brand-proprietary nozzle. An HPA gun uses an engine nozzle matched to the engine. Match your gun to one of the four types below, then read its guidance.
What length AEG nozzle do I need?
AEG air nozzles fit by length in millimetres and the length is platform-specific. An M4 uses roughly 21.4mm, an AK around 19.6mm, a G36 about 24.5mm, and long platforms like the SCAR-H (about 36mm) and SR25 (about 35mm) run longer. The reliable method is to measure the nozzle you are replacing and match that length, then feed-test. See the AEG page for the full length-by-gun table.
Are airsoft nozzles interchangeable?
Only within their own type and platform. An AEG air nozzle, a gas pistol loading nozzle, a GBBR nozzle and an HPA engine nozzle are unrelated parts that never cross over. Even within a type, AEG nozzles are length-specific and GBBR nozzles are brand-proprietary, so match both the type and your exact platform.
What is the difference between a nozzle and a valve?
A nozzle chambers and launches the BB (an AEG air nozzle pushes air behind the BB, a gas loading nozzle routes gas and feeds the BB). A valve controls gas flow (fill valves, output valves, knocker valves). Retailers often list gas pistol and gas rifle nozzles in the same category as valves, so on these pages we filter to the nozzles, but always read the product title to confirm you are buying the nozzle and not a valve.
