Steiner P4xi 1-4x42mm Sfp

The Steiner P4xi 1-4x42mm SFP riflescope is a compact tactical optic engineered for patrol rifles, AR-15 platforms, and modern carbines operating in dynamic close-quarters and mid-range environments. Law enforcement and military users demand optics that transition seamlessly from room-clearing distances to 400-yard precision shots, and the P4xi delivers exactly that capability. This scope combines true 1x magnification for both-eyes-open shooting with robust 4x zoom, making it ideal for operators who require speed and accuracy without sacrificing field of view or bulk.

The P4xi achieves its versatility through a second focal plane (SFP) optical design paired with a 42mm objective lens, delivering a bright, distortion-free sight picture across the entire zoom range. At 1x magnification, both eyes remain open for rapid target acquisition and situational awareness—critical when threats emerge at contact distance. As magnification increases to 4x, the reticle scales proportionally, maintaining holdover accuracy at extended ranges while the compact 14-inch tube profile keeps overall package weight minimal at 1.88 pounds. The rugged construction and proven Steiner glass coatings ensure reliable performance in harsh conditions without adding unnecessary weight to your carbine.

This optic suits patrol officers, tactical team members, 3-gun competitors, and AR platform shooters who prioritize speed in CQB while maintaining capability past 300 yards. The SFP design means your reticle remains accurate only at maximum magnification (4x), so hold precise aim when zoomed in for distant targets. Mounting is straightforward on any standard Picatinny rail system, and the compact footprint ensures co-witness with backup iron sights. Whether you're building a duty rifle, home defense platform, or training carbine, the Steiner P4xi delivers the optical performance and form factor that professionals trust.
