Small tool, big difference on game day
The Strike HPA Regulator Adjustment Key, known to players simply as the reg key, is a must-have for anyone running a High Pressure Air setup. It lets you fine-tune your regulator output pressure quickly, so you can hit a site FPS limit before the marshal seals your gun.
Precise, damage-free adjustment
The drive head is precision machined to grip the adjustment screw cleanly, resisting the slipping and rounding that improvised tools cause. Whether you are dialling in FPS for a specific site or fine-tuning your solenoid cycle, it gives you the leverage and control you need without harming the regulator housing.
Broad compatibility
While optimised for Strike regulators, the standard-size head fits the vast majority of HPA regulators used across the UK airsoft scene, making it a versatile addition to any toolkit.
Always to hand
A pre-drilled hole lets you attach it to a keyring or paracord loop, so it stays clipped to your kit rather than lost in the leaf litter. Remember it adjusts pressure only, not for bleeding tanks.
