Product Overview
The Burris FullField E1 3-9x40mm rifle scope is engineered to provide precise optical performance specifically for platforms chambered in .450 Bushmaster. This optic integrates essential features required for reliable engagement across varied conditions, establishing it as a utilitarian choice for hunters and shooters utilizing the .450 Bushmaster cartridge. Its design prioritizes optical clarity, robust construction, and practical reticle application for a defined ballistic profile.
Key Features
Optical System
The FullField E1 3-9x40mm utilizes a multi-coated lens system to optimize light transmission and mitigate glare. This configuration yields a clear, bright sight picture across its 3x to 9x magnification range, essential for target identification and shot placement. The 40mm objective lens effectively gathers ambient light, supporting utility in diverse lighting scenarios. Precision-ground lenses ensure accurate color reproduction and edge-to-edge clarity.
Robust Construction
Constructed from a single-piece main tube, this optic is designed to withstand the significant recoil impulse generated by the .450 Bushmaster cartridge. The internal components are securely housed, preventing shift under sustained use. The FullField E1 is nitrogen-purged to eliminate internal fogging due to temperature fluctuations and is O-ring sealed for waterproofing, ensuring operational reliability in adverse weather conditions.
E1 Reticle Design
The integrated Ballistic Plex E1 reticle offers clear holdover points, facilitating accurate trajectory compensation for the .450 Bushmaster. This design assists in rapid target acquisition and precise engagement without complex turret adjustments at common hunting distances. The reticle’s uncluttered presentation ensures an unobstructed field of view.
Application-Specific Utility
This particular FullField E1 variant is designated for the .450 Bushmaster, implying design considerations for its specific ballistic characteristics. The scope’s magnification range and reticle functionality complement the effective range and terminal performance of the .450 Bushmaster, optimizing the system for hunting applications where this cartridge excels.
