Vortex Viper PST GEN II 3-15×44 EBR-7C MRAD

Product Description

The Vortex Viper PST Gen II 3-15×44 EBR-7C MRAD is a first focal plane riflescope designed for long-range precision shooting and tactical applications. The 3-15x magnification range handles both mid-range engagements and extended distance shots without requiring a scope change.

The EBR-7C reticle uses MRAD measurements, which means your holdovers and windage corrections stay consistent with MRAD-based turret adjustments. First focal plane placement ensures the reticle scales with magnification, so your subtensions remain accurate whether you’re dialed to 3x or 15x.

This configuration suits precision rifle shooters who prefer MRAD-based ranging and correction, and who need a reticle that remains usable across the entire magnification range.

Key Facts

• Model: Vortex Viper PST Gen II 3-15×44 EBR-7C MRAD
• SKU: PST-3159
• Magnification: 3-15x
• Reticle: EBR-7C MRAD
• Objective Diameter: 44mm

Understanding First Focal Plane and MRAD Reticles

A first focal plane reticle grows and shrinks as you adjust magnification. This means the hash marks and subtensions on the EBR-7C reticle represent the same angular measurement at 3x as they do at 15x. If a target measures two MRAD wide in the reticle at low power, it still measures two MRAD at high power.

MRAD—milliradian—is a unit of angular measurement. One MRAD equals one meter at 1,000 meters, or 3.6 inches at 100 yards. Shooters who range, dial, and hold corrections in MRADs often find it simpler than mixing MOA and MRAD systems. The EBR-7C reticle includes numbered hash marks for windage and elevation holds, plus ranging references.

This scope pairs well with bolt-action precision rifles and designated marksman setups where you need to engage targets from 100 to 800 yards and beyond. The 3x low end gives you enough field of view for closer work, while 15x delivers the resolution needed to read wind and spot trace at distance.

What the 3-15x Magnification Range Offers

The 3-15x window is wide enough for versatility. At 3x, you retain situational awareness and a forgiving eye box, which matters when shooting from awkward positions or transitioning between targets. At 15x, you can resolve small details like mirage, bullet splash, and precise aim points on steel.

A 44mm objective lens balances light transmission with a compact profile. It gathers enough light for most shooting conditions without adding the bulk or exit pupil limitations of a 50mm or 56mm bell. This size also simplifies mounting, especially on rifles with standard-height rings.

If you’re building a do-all precision rifle or upgrading from a fixed-power optic, the 3-15x range covers field shooting, match stages, and hunting applications without forcing you into a second scope. Browse our full selection of riflescopes for other magnification and reticle options.

Choosing Between MRAD and MOA

MRAD and MOA both measure angles, and both work. The question is which system matches your ranging tools, ballistic solver, and training. If your rangefinder reads in meters or your ballistic app outputs MRAD corrections, an MRAD reticle and turret set eliminates conversion math in the field.

The EBR-7C reticle is a Christmas-tree style, meaning it includes multiple aiming points below center for quick holds on moving or multiple targets. The hash marks are numbered, so you can dial or hold with equal confidence. Shooters who compete in PRS or tactical matches often prefer this layout for stage efficiency.

Frequently Asked Questions

Q: What is the difference between the Viper PST Gen II and the original Viper PST?

A: The Gen II series represents Vortex’s update to the original Viper PST line, with refinements to the optical system, turret design, and reticle options. The Gen II models typically feature improved glass, revised turret profiles, and additional reticle choices including the EBR-7C MRAD found in this scope. Both generations use first focal plane reticles and are built for tactical and precision rifle applications, but the Gen II incorporates feedback from competitive shooters and military users.

Q: Is the EBR-7C reticle illuminated?

A: Call 817-393-4000 to confirm illumination features and brightness settings for this model.

Q: What scope rings or mount do I need for the Viper PST Gen II 3-15×44?

A: The Viper PST Gen II series uses a 30mm main tube diameter, so you will need rings or a mount sized for 30mm tubes. Ring height depends on your rifle’s action height, rail configuration, and whether you want a lower or higher cheek weld. For bolt-action rifles with a standard Picatinny rail, medium-height rings often provide adequate clearance for the 44mm objective bell. Call 817-393-4000 and we can walk you through ring selection based on your specific rifle.

Q: Can I use this scope for hunting in Texas?

A: Yes, the Vortex Viper PST Gen II 3-15×44 suits hunting applications where you need precise shot placement at varying distances. The 3x low end is usable in timber or senderos, and the 15x top end resolves detail on game animals several hundred yards out. The MRAD reticle gives you reference points for holdovers if you’re shooting beyond your zero distance. First focal plane reticles work well for hunters who range and dial or hold corrections rather than guessing trajectory.

Q: How does a first focal plane scope compare to a second focal plane scope?

A: In a first focal plane scope, the reticle scales with magnification, so the hash marks and subtensions remain accurate at any power setting. In a second focal plane scope, the reticle stays the same visual size regardless of magnification, so the subtensions are only correct at one specific power, usually the highest. First focal plane scopes give you flexibility to range and hold corrections at any magnification, which is why they are common in tactical and competition shooting. Second focal plane scopes often have simpler, less obtrusive reticles and are popular for hunting where you typically shoot at maximum magnification.

Q: Does Western Sport offer gunsmithing services for scope mounting and bore sighting?

A: Yes, Western Sport provides on-site gunsmithing services including scope mounting, ring lapping, and bore sighting. Owner and gunsmith Lance Rankin can ensure your Viper PST Gen II is properly torqued, aligned, and ready for live fire. Call 817-393-4000 to schedule gunsmithing work or to ask about turnaround times.
