Burris Xtr Ps 3.3-18x50mm Scr2 Mil Illum Overview

The Burris XTR PS 3.3-18x50mm SCR2 MIL Illuminated Riflescope (model BO201220) is a first focal plane (FFP) precision optic engineered to merge traditional mechanical tracking with advanced digital ballistic computing. Constructed from a single-piece, milled 6061-T6 aluminum housing with a robust 34 mm main tube, this riflescope is designed to withstand heavy recoil on tactical platforms. It features an illuminated SCR 2™ FFP reticle with selectable dual-color red/green illumination, a 50 mm objective lens, and an onboard Heads-Up Display (HUD) that feeds real-time ballistic calculations directly into the shooter's optical view.

Key Features

• Programmable Elevation Knob (PĒK) System: Driven by a clickless digital position sensor, the PĒK system replaces traditional mechanical clicks with smooth dial rotation, tracking adjustments down to a precise 1/30 MIL digital resolution.
• Onboard HUD Data Center: Displays critical information within the visual field, including dial-to-distance feedback, wind holds, wind speed/direction, density altitude, a digital scope level, angle compensation, and battery status.
• BurrisConnect Bluetooth Integration: Connects to mobile devices (iOS and Android) to upload custom ballistic profiles and up to 20 density altitude curves, allowing the scope to operate fully autonomously in the field without an active phone connection.
• Independent Power System: Operated by a single CR123A battery to power all onboard digital functions, meaning it does not draw mains power or use 240V chargers, rendering Australian SAA/RCM electrical compliance standards non-applicable.
• Versatile Parallax Adjustment: Features side parallax adjustment from 25 yards to infinity, providing sharp target focus across both close-range and extreme-distance targets.

Who is the Burris XTR PS 3.3-18x50mm SCR2 MIL Illuminated Riflescope for?

• Precision Rifle Series (PRS) and National Rifle League (NRL) tactical competitors — require an advanced FFP riflescope with immediate, clickless elevation tracking and high-resolution digital wind/drop adjustments, facilitated by the digital PĒK sensor's 1/30 MIL resolution and the broad 35 MIL maximum elevation travel.
• Medium-to-long range tactical hunters — benefit from the versatile 3.3x to 18x magnification range and 50 mm objective lens, which support fast target resolve at closer distances, compatibility with thermal clip-on units, and autonomous, on-the-fly density altitude calculations via the integrated HUD.

Less suitable for: ultra-lightweight backcountry mountain stalks where minimizing gear weight is critical; at a physical weight of 35.2 ounces (998 grams) without rings, a lighter, non-electronic hunting riflescope with a smaller 1-inch or 30 mm main tube would be more appropriate.
