The system type—whether it’s a drop-in kit, cylinder replacement, or a specific solenoid configuration—determines the installation complexity and performance characteristics of your HPA build. Drop-in kits are designed for straightforward installation into existing gearboxes, making them ideal for users seeking simplicity. Cylinder replacement systems, like the PolarStar Jack V2 HPA Unit, are great for those wanting to upgrade internal performance while retaining the original gearbox shell. Single solenoid designs, such as the Wolverine Airsoft INFERNO GEN 2 Spartan Edition, offer efficiency and easy tuning. This variety allows you to choose a system that matches your technical comfort level and performance goals, with options available for both basic upgrades and advanced custom builds.
