GPO Spectra 4x Rifle Scope 4-16x50i 30mm SFP G4i Drop Illum. Black

The GPO Spectra 4x Rifle Scope 4-16x50i 30mm SFP G4i Drop Illum is a precision long-range optic built for tactical shooters and hunters who demand accuracy beyond 300 meters. German Precision Optics engineered this scope to deliver repeatable performance in field conditions where magnification flexibility and fast target acquisition are non-negotiable. From law enforcement precision rifle teams to competitive long-range competitors, this 4-16x magnification range bridges the gap between close-quarters engagements and extended-distance engagements without sacrificing optical clarity.

The 50mm objective lens maximizes light transmission in low-light conditions, while the 30mm tube diameter provides robust elevation and windage adjustment travel—critical for compensating bullet drop at distance. The G4i illuminated reticle system features drop-compensation hashmarks calibrated for standard ballistic trajectories, enabling holdover adjustments without turret manipulation when seconds matter. As a second focal plane (SFP) design, the reticle subtensions remain accurate only at maximum magnification (16x), preserving point-of-aim accuracy for hunters and tactical operators who shoot across varying ranges. The illuminated center dot enhances target contrast in overcast or heavily shadowed environments, a proven advantage in real-world field use.

This scope is compatible with 30mm Picatinny-mount rings and mounts on any AR-10, bolt-action rifle, or modern rifle platform with a flat-top receiver. The 2.61-pound weight and compact 16-inch optical tube length minimize rifle top-heaviness, maintaining quick handling characteristics even on precision rifle builds. Law enforcement and military end-users will find the rugged, single-piece 30mm tube construction capable of withstanding field abuse, vibration, and repeated cleaning cycles. Installation requires only a proper torque wrench and ring alignment tools—standard equipment in any serious shooter's maintenance kit.
