Overview
The Steiner P4Xi 1-4x42mm SFP riflescope is engineered for explicit reliability and performance integration with patrol rifles and AR platforms. This compact tactical optic provides a versatile 1-4x magnification range, featuring a true 1x setting for rapid target acquisition and enhanced situational awareness in close-quarters environments. At its maximum 4x magnification, the P4Xi facilitates precise engagement at distances up to 400 yards, providing utility across diverse engagement parameters.
Constructed for operational durability, the P4Xi maintains Steiner’s established reputation for robust tactical optics. Its Second Focal Plane (SFP) reticle design ensures consistent reticle size irrespective of magnification, offering stable aiming points. This design simplifies holdovers and ranging for operators who prioritize a constant reticle appearance. As a critical component within a firearm accessory matrix, the P4Xi is built to withstand demanding field conditions, delivering consistent optical performance for professional duty applications or competitive shooting disciplines. The 42mm objective lens optimizes light transmission, yielding a clear sight picture, particularly beneficial in low-light conditions. The P4Xi represents a practical, dependable optical solution for precision rifle or carbine deployment.
Key Features
Optical Performance
The 1-4x magnification range allows for immediate adaptation across engagement distances. A true 1x setting provides an expansive field of view for rapid target acquisition and situational awareness in dynamic close-quarters scenarios. Transitioning to 4x magnification enables precise target identification and engagement at ranges up to 400 yards. The 42mm objective lens is calibrated to enhance light gathering capabilities, optimizing image clarity and contrast, particularly in suboptimal lighting conditions.
Reticle System
This optic features a Second Focal Plane (SFP) reticle. The SFP design maintains a constant reticle size across the entire magnification range. This configuration ensures consistent aiming point presentation, simplifying trajectory compensation and ranging procedures without the dynamic reticle size changes inherent in First Focal Plane (FFP) systems. This fixed reticle scale is often preferred for applications where a consistent sight picture is paramount.
Construction and Reliability
The Steiner P4Xi is manufactured to stringent tactical specifications, ensuring exceptional durability and resistance to environmental stressors. Its robust construction is designed to endure demanding field use, maintaining zero and optical integrity through shock, vibration, and adverse weather conditions. This commitment to reliability ensures consistent performance, positioning the P4Xi as a dependable choice for critical applications.
Platform Integration
Optimized for AR platforms, patrol rifles, and carbines, the P4Xi’s compact footprint and tailored magnification range make it an ideal optic for enhancing the operational effectiveness of these systems. Its design prioritizes ergonomic utility and seamless integration, ensuring the optic complements the host weapon system without impeding handling or balance.
