GPO USA 2-12x50i SPECTRA 6X Riflescope (G4i Reticle)

Description

True 30mm aircraft aluminum geometry anchors the GPO USA SPECTRA 6X Riflescope, featuring an illuminated G4i micro-dot reticle, massive 50mm objective lens, and side parallax focus. Designed for deep twilight big-game hunting, it delivers 100 MOA total elevation travel with 1/4 MOA clicks, yielding exceptional low-light image brightness while demanding medium to high scope rings.

Constructed from lightweight 6061-T6 aluminum, the 30mm one-piece tube withstands aggressive field abuse and mountain pack transit. Double HD optical glass elements suppress chromatic fringing along high-contrast target silhouettes. Dry nitrogen purging prevents internal fogging during cold morning shifts, achieving an IPX7 waterproof rating. At 23.6 ounces and 13.6 inches in length, this optic keeps hunting rifles balanced, highlighting practical GPO USA hunting scope value.

Key Features of GPO USA SPECTRA 6X

Big-game hunters buy GPO USA 2-12x50i SPECTRA 6X scopes to extend shooting hours into legal dawn and dusk limits. The large 50mm lens pulls critical ambient light when game animals emerge from thick cover.

• 50mm Double HD objective delivers sharp resolution across challenging low-light hunting scenarios
• 2-12x zoom range bridges dense timber shooting and 700-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 6X riflescope erector components absorb heavy recoil impulses from magnum calibers
• Continuous rotary illumination control offers stepless dimming with automatic power shutoff

Tactical Turret Calibration 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.

Medium Receiver Scope Ring Alignment

Mounting this 30mm tube requires 5.6 inches of rail space, making it an easy fit for standard two-piece bases. High scope rings position the 50mm objective bell clear of heavy sporter barrel contours. Torque ring screws to 15 to 18 in-lbs and base hardware to 40 to 45 in-lbs. Eye relief sits at 3.8 inches, providing a safe, forgiving visual pocket.

Twilight Optic Usability Maintenance Routine

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
