GPO USA 3-15x56i SPECTRA 5X Riflescope (G4i Reticle)

Description

Isolate medium game across dense timber through the GPO USA SPECTRA 5X Riflescope, featuring an illuminated G4i micro-dot reticle, 56mm objective, and side parallax focus. Designed for European-style stand hunting and late-dusk big game, it delivers 100 MOA total elevation travel with 1/4 MOA adjustments, granting extraordinary photon gathering while requiring high mounting rings.

Constructed from a single piece of aircraft-grade 6061-T6 aluminum, the 30mm chassis resists structural warping from over-torqued scope rings. Fully multi-coated optical glass surfaces suppress flare, keeping visual contrast high under bright midday sun. Dry nitrogen purging prevents internal fogging during cold morning shifts, achieving an IPX7 waterproof rating. At 29.3 ounces and 14.2 inches in length, this optic keeps rifles stable, highlighting practical GPO USA hunting riflescope value.

Key Features of GPO USA SPECTRA 5X

Late-season hunters buy GPO USA 3-15x56i SPECTRA 5X scopes to secure clean target identification during the final minutes of legal light. The illuminated G4i micro-dot pinpoints vital zones against shadowed backgrounds.

• 56mm multi-coated objective delivers sharp resolution across low-light hunting scenarios
• 3-15x zoom range bridges dense timber shooting and 800-yard open terrain precision
• 1/4 MOA capped turrets provide positive zero clicks without accidental field rotation
• 100 MOA elevation travel accommodates bullet drop on standard centerfire hunting loads
• Illuminated fiber-optic G4i reticle provides micro-dot brightness for bright sun and dark timber
• Side focus parallax dial eliminates image blur and reticle wander from 10 yards out to infinity
• SPECTRA 5X riflescope erector components absorb heavy recoil impulses from magnum calibers
• Continuous rotary illumination control offers stepless dimming with automatic power shutoff

Five Power Optical Travel Limits

Tempered internal leaf springs support the erector tube, eliminating tracking error across the entire 100 MOA travel spectrum. The 1/4 MOA turrets adjust clean with positive detents, maintaining true 1 percent tracking accuracy. Built to withstand 1000G shock loads, the system tolerates continuous magnum rifle firing strings. Operational temperatures span -20°F to 140°F, keeping internal damping lubricants stable without freezing or running.

Large Objective Scope Ring Placement

Mounting this 30mm tube requires high scope rings to ensure the 56mm objective bell clears sporter and medium contour barrels on bolt-action rifles. The central tube provides 5.6 inches of mounting space. Torque ring screws to 15 to 18 in-lbs and base hardware to 40 to 45 in-lbs. Eye relief sits at 3.74 inches, providing a safe, forgiving visual pocket.

High Magnification Handling Maintenance Steps

The side parallax knob turns with positive mechanical resistance, allowing deliberate focal correction without accidental movement. This large-objective optic is not engineered for ultralight mountain rifles where light weight is paramount, nor for non-magnified close-quarter combat. Practice systematic maintenance to ensure lifelong field reliability.

• Blow grit off optical lenses using clean air before wiping every 200 rounds
• Check ring mount fastener torque with an accurate tool every 500 rounds
• Clean battery contacts and install a fresh CR2032 cell every 12 months
