Vortex Viper PST GEN II 2-10×32 EBR-4 MRAD

Product Description

The Vortex Viper PST Gen II 2-10×32 EBR-4 MRAD is a first focal plane riflescope built for precision rifle applications where low-light capability and accurate holdovers matter most. This magnification range bridges close-quarter work and mid-range precision without the weight penalty of larger objective lenses.

First focal plane reticles scale with magnification, meaning your MRAD subtensions remain accurate at any power setting. The EBR-4 MRAD reticle provides precise holdover and windage reference points using the milliradian angular measurement system favored by long-range shooters and military marksmen.

Compact riflescopes in the 2-10x range suit tactical carbines, scout rifles, and hunting applications where fast target acquisition at low power and detailed resolution at higher magnification are both required.

Key Facts

• Model: Vortex Viper PST Gen II 2-10×32 EBR-4 MRAD
• SKU: PST-2105
• Magnification Range: 2-10x
• Reticle Type: EBR-4 MRAD
• Focal Plane: First focal plane

Why First Focal Plane Matters for MRAD Reticles

First focal plane placement means the EBR-4 reticle grows and shrinks as you adjust magnification. At 2x, the reticle appears smaller; at 10x, it appears larger. Crucially, the spacing between hash marks always represents the same angular measurement downrange.

If you dial to 6x and measure a target as two milliradians wide using the EBR-4 grid, that measurement is correct. Change to 10x without touching your turrets, and the same target still measures two milliradians. This consistency allows you to range, hold for wind, and compensate for drop at any magnification without mental math or reticle-specific correction factors.

Second focal plane scopes lock the reticle size regardless of zoom, so subtensions are only accurate at one specific magnification. For tactical and precision rifle shooting where quick decisions under stress are routine, first focal plane eliminates a variable.

Pairing a 2-10×32 Optic with Your Rifle

The 2-10x magnification window suits barrels from 10.5 inches through 20 inches in common tactical calibers. Low magnification enables both-eyes-open shooting and wide field of view inside 50 yards. Higher magnification resolves detail and confirms point of impact out to 600 yards and beyond, depending on cartridge and shooter skill.

A 32mm objective lens gathers enough light for most shooting conditions without adding the bulk of a 44mm or 56mm bell. Smaller objectives also allow lower mounting height, which improves cheek weld consistency and reduces the need for unusually tall scope rings. Many precision shooters prefer this compact profile on rifles that must move between vehicles, cases, and shooting positions quickly.

Understanding the MRAD System

MRAD stands for milliradian, an angular unit equal to one-thousandth of a radian. At 100 yards, one milliradian equals 3.6 inches; at 100 meters, it equals exactly 10 centimeters. The metric relationship makes range estimation and ballistic math faster once you learn the system.

The EBR-4 reticle uses MRAD-based hash marks for both elevation and windage, letting you hold off-center for wind or bullet drop instead of dialing turrets for every shot. Competitive shooters and military snipers favor MRAD because the math scales cleanly across distances and matches most ballistic software output.

Frequently Asked Questions

Q: What is the difference between the Viper PST Gen II 2-10×32 and other Viper PST models?

A: The Viper PST Gen II 2-10×32 uses a 32mm objective lens and covers 2-10x magnification, making it more compact and lighter than larger models like the 5-25×50. The 2-10x range suits medium-range precision and tactical carbines, while higher-magnification Viper PST scopes are built for long-range target shooting and competition.

Q: Is the EBR-4 MRAD reticle illuminated on this model?

A: Call 817-393-4000 to confirm whether this specific SKU includes reticle illumination, as Vortex offers both illuminated and non-illuminated versions of the Viper PST Gen II line.

Q: What rifles pair best with a 2-10×32 scope?

A: The Vortex Viper PST Gen II 2-10×32 pairs well with AR-15 carbines, bolt-action precision rifles in .308 or 6.5 Creedmoor, and scout-configured hunting rifles. The magnification range covers close-range defensive work and mid-range precision without the size and weight of larger optics.

Q: Can I use MRAD reticle holdovers if my turrets are in MOA?

A: Mixing MRAD reticles with MOA turrets creates confusion during shooting, because your holdover reference points and your dial adjustments use different angular units. Most shooters match reticle and turret measurements for consistency. The Viper PST Gen II 2-10×32 EBR-4 MRAD is designed for use with MRAD turret adjustments.

Q: Do I need special rings to mount the Viper PST Gen II 2-10×32?

A: You need 30mm scope rings that match your rifle’s mounting system, such as Picatinny or Weaver-style bases. Ring height depends on your rifle’s stock dimensions and whether you run a raised cheek rest or night-vision device in front of the scope. Call 817-393-4000 and we can recommend ring height and mounting options for your specific rifle.

Q: How does first focal plane affect reticle visibility at low magnification?

A: At 2x magnification, the EBR-4 reticle appears smaller and finer than it does at 10x, because the reticle scales with zoom. Some shooters find fine reticles harder to see at low power in dim light, while others appreciate the uncluttered view. Illuminated reticle versions address low-light visibility if your eyes or shooting conditions require it.
