Vortex Viper PST GEN II 5-25×50 EBR-7C MRAD

Product Description

The Vortex Viper PST Gen II 5-25×50 EBR-7C MRAD is a first focal plane riflescope designed for precision long-range shooting and tactical applications. This riflescope combines a 5-25x magnification range with a 50mm objective lens and the EBR-7C reticle scaled in milliradians.

The Viper PST Gen II is built for shooters who need repeatable zero and precise turret adjustments across extended distances. The MRAD-based reticle and turrets allow fast wind and elevation holds without math conversions.

This optic suits competitive precision rifle shooters, hunters working open country, and tactical operators who need ranging and holdover capability in a single system.

Key Facts

• Model: Vortex Viper PST GEN II 5-25×50 EBR-7C MRAD
• Magnification Range: 5-25x
• Objective Lens Diameter: 50mm
• Reticle: EBR-7C MRAD
• Brand: Vortex

Why the EBR-7C MRAD Reticle Matters

The EBR-7C reticle is a Christmas tree-style holdover pattern calibrated in milliradians. Because this is a first focal plane scope, the reticle grows and shrinks with magnification changes. That means your MRAD measurements stay true at any power setting.

Shooters using this reticle can dial elevation or hold directly on the tree for wind and drop corrections. The MRAD system pairs naturally with ballistic apps and range estimation formulas common in precision rifle shooting.

If you are new to MRAD or coming from MOA scopes, understand that one milliradian equals 10 centimeters at 100 meters or roughly 3.6 inches at 100 yards. Turret and reticle match, so dialing and holding use the same unit.

What the 5-25x Magnification Range Offers

The 5x low end provides enough field of view for target acquisition and close-range work inside 300 yards. At 25x, you gain the resolution needed to spot impacts, read mirage, and place shots on small targets past 1,000 yards.

This magnification spread works well on gas guns and bolt rifles alike. Competitors often run mid-range power during stages that mix near and far targets, then crank up for known-distance strings.

The 50mm objective gathers enough light for dawn and dusk shooting without adding the bulk of a 56mm bell. Most shooters mount this scope in medium or medium-high rings depending on the rifle and whether they use lens covers.

Choosing Between Viper PST Gen II and Other Riflescopes

The Viper PST Gen II sits between entry-level long-range optics and top-tier competition glass. It offers first focal plane functionality and exposed turrets at a price point accessible to serious recreational shooters.

If you are deciding between this and a second focal plane scope, remember that FFP keeps your reticle measurements accurate at any zoom level, but the reticle appears smaller at low magnification. Shooters who rarely dial and prefer a bold reticle may prefer SFP designs.

The MRAD version of this scope suits those already using metric-based ballistic tools or learning to range with a reticle. MOA versions exist for shooters who prefer that system. Both do the same job; pick the one that matches your workflow.

Frequently Asked Questions

Q: What rifles work best with the Viper PST Gen II 5-25×50 EBR-7C riflescope?

A: This riflescope works well on bolt-action precision rifles in 6.5 Creedmoor, .308 Winchester, 6mm Creedmoor, and magnum cartridges, as well as AR-10 platforms and other semi-autos built for accuracy. The 5-25x range and MRAD reticle suit any rifle used for shooting beyond 300 yards. Choose your ring height based on objective clearance and whether you want a chin weld or cheek weld.

Q: How does the EBR-7C MRAD reticle differ from the EBR-2C?

A: The EBR-7C offers a finer, more detailed Christmas tree holdover pattern compared to the EBR-2C, giving more precise aiming points for wind and elevation holds at extended range. Both are MRAD-based first focal plane reticles, but the EBR-7C provides additional stadia lines that competitive and tactical shooters prefer for fast corrections without dialing. Call 817-393-4000 if you need help choosing between reticle options.

Q: Is the Vortex Viper PST Gen II 5-25×50 good for hunting or just competition?

A: This riflescope works for both hunting and competition, especially for hunters who take long shots in open terrain or mountainous country. The 5x low end gives enough field of view for scanning, and the 25x top end lets you confirm target details and placement at distance. The scope is heavier than a traditional hunting optic, so it suits rifles carried on a sling or in a vehicle rather than spot-and-stalk work.

Q: What is the difference between MRAD and MOA, and does it matter?

A: MRAD (milliradian) and MOA (minute of angle) are two angular measurement systems used for turret adjustments and reticle subtensions. One MRAD equals about 3.6 inches at 100 yards; one MOA equals about 1.047 inches at 100 yards. MRAD works in base-10 and pairs naturally with metric ballistic solvers, while MOA uses finer clicks. Either works; choose the system your shooting community or training uses.

Q: Can I mount the Viper PST Gen II 5-25×50 on an AR-15 or does it require a bolt gun?

A: You can mount this riflescope on an AR-15, but the magnification range and intended use suit precision AR builds in .223 Wylde, 6.5 Grendel, or .224 Valkyrie rather than standard carbines. Most shooters pair this scope with heavy-barrel rifles on bipods for long-range work. For general-purpose AR-15 use inside 300 yards, a lower-magnification optic or red dot makes more sense.

Q: Does Western Sport provide mounting and bore sighting services for riflescopes?

A: Western Sport offers gunsmithing services on site, including scope mounting and bore sighting. Proper ring height, torque, and alignment ensure your optic performs as designed. Call 817-393-4000 to schedule service or ask about mounting options for your rifle and the Viper PST Gen II.
