Precision. Speed. Reliability. Your airsoft game hinges on these qualities, and the Holy Warrior S1 EXPS3 delivers them all. Designed for the serious UK player, this red dot sight transforms your replica into a rapid-target-acquisition machine. Whether you’re clearing a tight urban CQB arena or engaging foes across open woodland, the S1 EXPS3 keeps you locked on target.
Unmatched Clarity and Field of View
The S1 EXPS3 features a high-transmittance lens coating that boosts image brightness without sacrificing clarity. You gain a generous 68° field of view, so no movement goes unnoticed.
- Bright red reticle with adjustable intensity levels adapts to bright summer days or overcast UK skies.
- Multi-layer lens treatment reduces glare and increases contrast for clear sight of your target, even under foliage or low light.
Built to Withstand UK Conditions
Rain, mud or sand—challenge your gear, not your sight. The S1 EXPS3 uses aircraft-grade 7075 aluminium and a sealed, nitrogen-filled housing to prevent internal fogging.
- IP67 water resistance keeps electronics safe in sudden downpours.
- Shock-resistant internals endure recoil from high-power spring builds.
- Compact form factor keeps your rig lightweight, preserving speed during dynamic play.
Quick Detach Mount for Swift Swaps
Time lost mounting or dismounting optics can cost you the game. The S1 EXPS3’s quick-detach mount uses a fool-proof lever system:
- Lock it on your 20 mm rail in seconds, zero tools needed.
- Release instantly to switch between red dot and magnifier setups.
- Consistent return-to-zero performance when reattached keeps your shots accurate.
Night Vision Compatibility for All Ops
UK night games push your kit to its limits. The S1 EXPS3 retains sight-picture integrity when used with Gen 1 and Gen 2+ night vision devices.
- Reticle remains crisp under IR illumination.
- Low-light modes conserve battery while ensuring visibility.
- Seamless integration with helmet-mounted setups for low-profile covert ops.
Power and Battery Life You Can Rely On
A sight is only as good as its uptime. The S1 EXPS3 runs on a single CR123A battery, delivering 100’s of hours of continuous use on medium brightness.
- Integrated digital display shows remaining power at a glance.
- Auto-shutoff feature preserves battery when idle.
- Compatible with rechargeable cells for eco-conscious players.
