The Burris Fullfield 4-16x50 Plex SPA KSB (Model Year 2025) is a versatile, mid to long-range riflescope designed for hunters and target shooters who value optical clarity and modularity.

As part of the 2025 refresh of the Fullfield line, this model is built to be shorter, lighter, and more compact than its predecessors without sacrificing durability or light gathering.

• SPA (Side Parallax Adjustment): Unlike standard hunting scopes with a fixed parallax, this model features a dedicated side-focus knob. This allows you to eliminate parallax error and maintain a sharp target image from 25 yards to infinity, which is critical when shooting at high (16x) magnification.

• KSB (Knob Synergy Burris): This is a modular turret system. The scope comes with sleek, capped knobs for a snag-free profile in the field. However, the "Synergy" design allows you to easily swap these for Advanced Exposed Knobs or Custom Ballistic Knobs laser-etched to your specific calibre and load data.

• Plex Reticle: A classic, clean, non-illuminated crosshair. The heavy outer posts transition to fine centre wires, guiding your eye to the centre quickly while keeping the target visible for precise shot placement.

• 4x Zoom System: The proprietary 4x optical system provides a broad magnification range (4x to 16x), making it equally effective for close-range target acquisition and long-distance precision.

• 50mm Objective Lens: A large objective lens combined with high-performance, multi-coated glass ensures excellent light transmission. This is particularly noticeable at dawn or dusk (low-light conditions) and when using the higher end of the 16x zoom.

• Nitrogen-Filled Construction: The 1-inch main tube is nitrogen-purged to be 100% waterproof, fog-proof, and shockproof.
