Gpo Scope Spectra 4X 4-16X50 - G4I Reticle 30Mm Matte

The GPO Spectra 4-16x50 with G4i reticle is a versatile mid-range rifle scope built for hunters and shooters who demand optical quality without compromise. At 4x magnification you get a wide field of view for quick target acquisition in thick timber or at close range; crank it to 16x and you've got the glass to stretch shots to distance with confidence. The 50mm objective lens gathers plenty of light, keeping your image bright even when the sun dips low or clouds roll in—the kind of performance that matters when your hunt is on the line.

This GPO scope is engineered around a philosophy of clean, functional precision. The DoubleHD objective lens technology delivers the optical resolution serious shooters expect, while the iCONTROL illumination system lets you dial in your reticle brightness to match whatever conditions you're facing. That means faster target pickup, whether you're glassing in low light or dealing with bright snow glare. The PASSIONtrac turrets give you repeatable, tactile feedback for windage and elevation adjustments, so your zeros stay put and your comeups are dead-on.

The G4i ballistic micro-dot reticle is purpose-built for real-world shooting—clear enough to pick out your target, fine enough to execute precise holds at distance. Turret adjustments ship at .36 inches per click at 100 yards (0.1 mrad), with 85 minutes of total adjustment available for zeroing and long-range compensation. If your hunting or match routine demands something more specific, GPO offers custom turret options to dial in your exact ballistics. The 30mm matte tube blends into any rifle and resists reflection. Built tough, backed by German engineering, and ready for whatever country you're hunting.

Frequently Asked Questions

What magnification range is best for hunting?

The 4-16x magnification range on this scope covers nearly every hunting scenario. The 4x end excels in timber and tight country where you need a wider field of view and faster sight picture; the 16x end lets you make ethical, confident shots at distance when the terrain opens up. You adjust between them based on your situation—no compromise either way.

Can I get custom turrets for my specific loads?

Yes. GPO offers custom turret options, so you can have the elevation turret calibrated for your exact ballistics. This removes guesswork in the field and lets you dial your real zero instead of relying on subtension marks in the reticle.

Will this scope work in low light?

The 50mm objective and DoubleHD lens technology are designed to maximize light transmission, giving you a bright image in dim conditions—dawn, dusk, or overcast days. The iCONTROL illumination system lets you dial the reticle brightness to match whatever light you have, which speeds up target acquisition in those critical low-light windows.

What is the tube diameter and will it fit my rifle?

This scope has a 30mm tube. Most modern rifles and quality rings support 30mm tubing, but you'll want to verify your ring and mount specifications before purchase to ensure compatibility.
