Build Quality & Components

Machined from aircraft-grade 6061-T6 aluminum with a matte black finish, the P4Xi is built to endure heavy recoil, drops, and extreme conditions. Fully multi-coated high-definition glass delivers outstanding clarity, color fidelity, and light transmission. The P3TR reticle is etched and illuminated via LED for consistent performance. O-ring seals and nitrogen purging ensure waterproof and fogproof integrity. Fit and finish are Steiner-quality — precise turrets, smooth adjustments, and zero shift under stress — backed by Steiner’s heritage and strong warranty.

Handguard & Modularity — Standout Feature

True 1-4x magnification provides 1x for rapid close-quarters acquisition and 4x for precise mid-range shots. The illuminated P3TR reticle (horseshoe with center dot) enables fast target ID and holdovers. Generous 3.5–4 inch eye relief supports comfortable shooting with high-recoil rifles. 30mm tube and audible/tactile turrets offer precise windage/elevation adjustments. Versatile mounting on ARs, bolt guns, or tactical rifles — perfect for CQB to 300-yard engagements with quick transitions.

Accuracy & Performance

High-definition glass and fixed parallax deliver crisp, distortion-free views with excellent light gathering. The illuminated P3TR reticle excels in low-light and dynamic scenarios — fast acquisition at 1x, precise placement at 4x. Performance is elite — bright, clear sight picture in all conditions, no bloom, and consistent zero retention under recoil — ideal for tactical, duty, or hunting use.

Installation & Real-World Durability

Mounts easily on 30mm rings (torque to spec) and zeros quickly. Durability is Steiner legendary — shockproof against heavy recoil, waterproof to IPX7, fogproof, and built to survive drops and abuse. LED illumination (CR2032) provides reliable low-light performance. Proven in military/LE and tactical use with minimal maintenance — a lifetime optic for hard use.
