What our Experts Think
-
Extended Hunting Versatility: 4–20×50 magnification delivers a strong balance of close-range flexibility and long-range target precision, ideal for open-country hunting and precision rifle setups.
-
MIL-DOT SFP Reticle Simplicity: Second focal plane Mil-Dot reticle provides a clean, traditional aiming system with reliable holdover references at higher magnification.
-
Clear, Bright Optics: Fully multi-coated lenses ensure strong light transmission, improved brightness, and accurate color reproduction across the full zoom range.
-
Solid Low-Light Performance: 50mm objective lens helps maintain usable image brightness at dawn and dusk, when game movement is most active.
-
Tactical-Grade Adjustments: 0.1 MIL click turrets with side parallax (10 yards to infinity) enable precise focusing and repeatable dialing for distance shooting.
-
Rugged Field Construction: Aircraft-grade aluminum one-piece tube with waterproof, fog-proof (argon purged), and shockproof sealing ensures reliability in harsh conditions.
-
Comfortable Shooting Setup: ~3.6" eye relief provides safe, consistent shooting position across a wide range of calibers and recoil levels.

Maintenance Tips
-
Clean lenses properly
Use a blower first to remove dust, then a microfiber cloth with lens-safe cleaner to protect fully multi-coated glass and avoid scratches or haze buildup.
-
Always use lens caps when not in use
Prevents dust, oil, and debris from degrading optical clarity and coating performance during storage or transport.
-
Store in a dry, stable environment
The scope is waterproof and argon-purged, but dry storage helps maintain long-term seal integrity and prevents internal fogging.
-
Avoid heavy impacts and recoil abuse
Built from aircraft-grade aluminum and shockproof construction, but repeated hard knocks can still affect zero retention and internal alignment.
-
Keep turrets clean & protected
Capped turrets should be checked for dust or grit; avoid forcing clicks to maintain smooth, precise MIL adjustments.
-
Check mount torque regularly
Ensure rings and base are evenly tightened to prevent scope movement and maintain consistent zero under recoil.
-
Reconfirm zero after use or transport
Especially after rough handling or extended shooting sessions to ensure accuracy stays consistent.
-
Do not disassemble the scope
Internal nitrogen/argon sealing and optical alignment are factory-set—opening it can permanently damage performance.
