Airtac HPA Adapter - GHK G5/M4 to M4 (MODULAR) - Plug & Play

Key Features:

• Essential HPA adapter for the GHK G5 Gas Blowback Rifle (also compatible with many GHK M4 GBBRs).
• M4 Magazine Conversion: Allows the G5 to feed from widely available M4/AR-15 AEG magazines (Mid/High-Cap), providing massive capacity gains.
• HPA Conversion: Converts the G5 GBBR to run reliably on High-Pressure Air (HPA), eliminating severe cool-down and maximizing FPS consistency.
• Recoil Retention: Engineered to allow the user to maintain the GHK G5's signature heavy blowback and realistic bolt function, now with stable air pressure.
• Modular & Plug and Play: Simple installation—replaces the stock magazine for immediate conversion to the HPA/M4 feed system.
• Durable Construction: Built by Airtac using high-strength materials for a strong, airtight connection and field resilience.
• Performance Boost: Maximizes FPS and ROF stability, making the G5 fully viable for sustained, full-auto skirmishing.

Unlocking GBB Potential: Airtac GHK G5/M4 Modular HPA Adapter

The GHK G5 Gas Blowback Rifle is revered for its mechanical realism, powerful recoil, and robust build, but its operational drawback lies in its massive gas consumption and susceptibility to cool-down. The Airtac GHK G5 / M4 HPA Adapter, available at Bespoke Airsoft, is the definitive upgrade that transforms this rifle into a primary weapon capable of consistent, sustained, high-volume fire.

Uncompromised Recoil with HPA Consistency

The core achievement of this adapter is performance consistency. HPA completely resolves the GHK system's gas flaws by providing an unlimited, highly stable air source, thereby maximizing FPS and ROF stability and eliminating cool-down, even during prolonged full-auto bursts. C

rucially, the adapter is engineered to allow the system to continue delivering the GHK's famous heavy blowback and realistic bolt cycling, preserving the immersive experience GBB users demand, but now with flawless reliability.

Modular Capacity and Plug and Play Solution

This adapter solves the capacity and cost equation. By converting the magazine well to accept universal M4 AEG magazines (Mid-Caps or High-Caps), players gain access to 100+ rounds of ammunition per mag, drastically reducing operational costs associated with expensive GHK magazines.

The "Modular" and "Plug and Play" design ensures easy installation—it replaces the stock magazine and provides a secure, airtight connection for the HPA line, making it a mandatory component for Milsim and competitive players who require GBB realism without the usual compromises.
