HPA Engines – The power source behind your airsoft precision

Looking for a powerful, reliable and fully customisable airsoft experience? HPA engines are at the heart of every advanced High Pressure Air system. These drop-in units replace your traditional gearbox or GBB mechanism and offer unrivalled shot consistency, minimal wear and tear, and maximum control over your FPS and ROF.

What makes HPA engines so special?

Unlike traditional electric or gas-powered systems, HPA engines run on compressed air supplied by an external tank and regulator. This ensures extremely stable performance – regardless of weather conditions or rate of fire. Many models are programmable, allowing you to easily switch between semi, burst and full-auto.

What will you find in this category?

• Drop-in HPA engines for V2, V3 and other gearbox platforms
• GBBR conversion kits – turn your GBB into an HPA monster
• Programming tools & triggers – for extra precision settings
• Options for M4, AK, MP5, ARP9, VSR-10, GBB pistols and more

Top brands we carry:

Who is an HPA engine ideal for?

• Speedsofters who demand maximum consistency with every shot
• Tech enthusiasts who want to tweak their replica down to the last detail
• Players in varying playing environments: CQB, woodland and milsim
• Anyone who wants to upgrade their AEG or GBB to the highest level of performance

Switch to the ultimate upgrade – an HPA engine will transform your replica into a precision instrument.
