The HK Army Hostile XLP is a premium adjustable on-tank regulator built from aircraft-grade aluminium, designed for players who want precise pressure control and a fast, reliable setup. Adjustable from 40 to 150psi via an easy-access adjustment point with a coloured micro pressure gauge, it covers the full operating range of most HPA airsoft engines.
The quick-disconnect fitting makes attaching and detaching your flex line fast — no threading and unthreading at the gun end every time you gear up or down. The fast recharge rate maintains consistent output pressure shot to shot, and the field/tournament lock keeps you compliant once you’ve passed chrono. Comes with an EXO travel case for protection between games. Available in multiple bold anodised colour finishes.
