HPA Adapter VMP Series to Shotgun Shell

Description

Ultra-Compact HPA Performance: AirTac VMP Series to Shotgun Shell Adapter

Take your VMP platform to the next level with the AirTac HPA Adapter VMP Series to Shotgun Shell. Designed for VMP-1 and VMP-2 platforms, this compact HPA conversion adapter allows you to move away from traditional gas magazines and run your replica from standard airsoft shotgun shells instead.

The result is an ultra-compact and lightweight setup that is particularly well suited to CQB, speedsoft and minimalist airsoft builds. By combining an integrated HPA valve and gas routing system with a compact shotgun shell feed system, AirTac has created an unusual but highly practical alternative to conventional VMP magazine setups.

The adapter uses a standard HPA fitting connection and is designed for plug-and-play installation, meaning there is no need to modify a donor magazine. Shotgun shells are compact and easy to carry, while the reduced profile helps keep your VMP setup lightweight and responsive during fast-paced games.

The “Pro” Take

This is one of those upgrades that completely changes the character of a VMP. Rather than simply replacing a gas magazine with an M4 magazine adapter, the AirTac shotgun shell system keeps everything remarkably compact and gives the VMP a distinctive minimalist appearance.

For players who spend a lot of time in CQB or speedsoft environments, the reduction in bulk can make a noticeable difference. Shotgun shells are small, easy to carry and quick to grab for reloads, while the HPA system removes the usual dependence on gas magazine pressure during extended firing.

The adapter is also a particularly interesting choice for anyone building a custom VMP. It provides another route into HPA without turning the replica into a bulky magazine-fed platform, making it a great option for players who prioritise mobility and a clean, lightweight setup.

UK Spec & Site Performance

HPA systems allow the user to regulate the pressure supplied to the replica, meaning the final muzzle energy will depend on the regulator setting, replica configuration and BB weight. Always chrono your completed setup before use and adjust it to comply with your chosen site’s limits.

Important: AirTac specifies a maximum operating pressure of 150 PSI for this adapter. The manufacturer also recommends using regulated air with a secondary regulator and checking the PSI before connecting the system. Never connect the adapter directly to an unregulated high-pressure air source or CO2 system.
