GPO USA 4-16x50i Spectra Riflescope (G4i Reticle)

Description

Secure sharp extreme distance target resolution with the GPO USA Spectra Riflescope, featuring an illuminated G4i micro-dot reticle, 50mm objective, and side parallax focus. Tailored for open-country hunters and target shooters, it delivers 100 MOA total elevation travel with 1/4 MOA clicks, yielding daylight-bright aiming clarity while requiring disciplined cheek placement at maximum zoom.

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 24.3 ounces and 13.9 inches in length, this optic keeps rifles stable, highlighting practical GPO USA hunting riflescope value.

Key Features of GPO USA Spectra

Precision hunters buy GPO USA 4-16x50i Spectra scopes to acquire high-magnification reach in low-light hunting scenarios. The illuminated fiber-optic G4i micro-dot draws the eye directly to center-mass targets.

• 50mm multi-coated objective delivers sharp resolution across dynamic hunting distances
• 4-16x zoom range bridges medium 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 riflescope erector components absorb heavy recoil impulses from magnum calibers
• Continuous rotary illumination control offers stepless dimming with automatic power shutoff

Illuminated Reticle Erector Cell Tolerances

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 semi-automatic centerfire cycling. Operational temperatures span -20°F to 140°F, keeping internal damping lubricants stable without freezing or running.

30mm Monotube Receiver Rail Interface

Mounting this 30mm tube requires 5.6 inches of rail space, making it an easy fit for standard two-piece bases. Medium or high rings position the 50mm objective bell clear of sporter rifle barrel contours. Torque ring screws to 15 to 18 in-lbs and base hardware to 40 to 45 in-lbs. Eye relief sits at 3.74 inches, providing a safe, forgiving visual pocket.

Precision Field Usability Service Regimen

The zoom ring operates with fluid mechanical resistance, allowing deliberate power selection without slipping. This versatile hunting optic is not engineered for extreme close-quarters dynamic tactical room clearing. Adhere to a standard service routine to maintain optical readiness.

• 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
