Overview
The Burris Fullfield 4-16x50mm ILL E3 riflescope is engineered for shooters who demand precision and adaptability across diverse environments and ranges. This optic integrates a robust optical system with the utility of an illuminated E3 reticle, providing a clear sight picture and essential ballistic hold points when conditions are less than ideal. Optimized for reliable performance, the Fullfield E3 series delivers consistent output for critical engagements.
Key Features
Optical Performance
The 4-16x magnification range provides the versatility required for both medium-range target identification and extended-range precision. Coupled with a large 50mm objective lens, the optic maximizes light transmission, ensuring a bright and sharp image, particularly in low-light scenarios. Burris utilizes multi-coated lenses to optimize clarity, contrast, and color fidelity, minimizing glare and reflections.
E3 Illuminated Reticle
The core of this optic’s utility is the E3 Illuminated Reticle. This reticle is designed to provide trajectory compensation for various cartridges and wind drift correction, enhancing hit probability at extended distances. The illumination feature ensures the reticle remains highly visible against dark targets or in dim conditions, allowing for rapid target acquisition and precise shot placement when every second counts.
Robust Construction
Constructed from a single-piece tube, the Fullfield 4-16x50mm ILL E3 is built to withstand the rigors of field use. The optic is O-ring sealed and nitrogen purged, rendering it fully waterproof and fog-proof, maintaining operational integrity regardless of precipitation or temperature fluctuations. Its shock-resistant design ensures the internal components remain stable and zero is held, even under heavy recoil.
Precision Adjustment System
Equipped with positive and repeatable windage and elevation adjustments, this riflescope allows for precise zeroing and on-the-fly corrections. The tactile feedback ensures confident adjustments, enabling shooters to fine-tune their point of impact with accuracy.
