In its original configuration, the GK1 is unregulated, allowing extremely high output levels. The regulated V3+ version adds improved shot-to-shot consistency and efficiency, while retaining full adjustability via both the regulator and power wheel. This makes it particularly suitable for markets with power limits, including the UK 6 ft\/lb and 7.5 Joule categories. The regulator allows safe and precise tuning below 6 ft\/lb where required, making it a compliant and practical choice for UK shooters.\u003c\/p\u003e\n\u003cp\u003eThe GK1 V3+ Regulated includes the regulator, forward manometer, K1-style fill port, and reservoir adapter plug. The air reservoir remains unchanged, and existing V3 models can be converted using the regulator kit. Available in calibres from \u003cstrong\u003e.177 through to .30\u003c\/strong\u003e, this configuration offers outstanding flexibility across different shooting disciplines.
