Talley Fierce Rivalry Picatinny Rail — Short Action, 20 MOA, Black Anodized | PSM258779 (UPC: 810301024229)
Push your Fierce rifle farther with the Talley Fierce Rivalry Picatinny Rail for Short Action receivers. Purpose-built with a 20 MOA forward cant, this one-piece, black anodized base preserves more of your scope’s internal elevation so you can dial long, stay closer to optical center, and maintain superior tracking. Precision-machined to MIL-STD-1913 spec, the Rivalry rail delivers rigid alignment for modern long-range optics, quick-detach mounts, and NV/thermal clip-ons—an ideal upgrade for hunters and competitors who demand dependable zero and repeatable performance.
Why This Talley 20 MOA Rail Stands Out
Reach farther with confidence: The integrated 20 MOA cant (≈ 5.8 mils) effectively raises your zero, leaving more “up” to dial for extended-range shots.
One-piece rigidity: Continuous rail construction enhances alignment and strength compared to two-piece bases, helping your scope track true and hold zero.
True Picatinny geometry: MIL-STD-1913 machining ensures consistent clamping force and compatibility with quality rings and QD mounts.
Lightweight & weather tough: Hard black anodized finish over precision-machined aluminum resists corrosion and abrasion while keeping ounces off mountain rigs.
Rival/Rivalry footprint: Designed around Fierce Rival / Rivalry short-action receivers (verify your exact model, hole spacing, and thread size before installation).
Pro tip: A canted base is especially valuable if your scope has limited internal elevation or you’re pushing sleek, high-BC cartridges well past your 100-yard zero.

Real-World Benefits
More usable elevation: Keep your erector system closer to optical center for better image quality and more reliable tracking—while still dialing to distance.
Flexible ring placement: Full-length slots simplify eye-relief setup and create space for clip-on NV/thermal devices without compromising ring position.
Consistency under recoil: Proper spec and one-piece rigidity help reduce scope creep and point-of-impact shift in tough conditions.
Ideal Use Cases
Backcountry & open-country hunting: Maximize dial range for high-odds first-shot hits on elk, mule deer, and pronghorn.
PRS-style practice & club matches: Consistent base geometry for repeatable dope and quick stage prep.
Night & thermal setups: Full-length Picatinny facilitates front-mounted devices while maintaining proper ring spacing.
Quick Installation Guide
Confirm fit: Verify Fierce Rival/Rivalry short-action footprint, hole spacing, and receiver thread spec.
Prep parts: Degrease receiver holes, screws, and rail underside; lightly oil exterior contact areas if you’re in wet/salty environments.
Set & align: Place the rail; ensure bolt travel and ejection are unobstructed.
Threadlocker: Apply a small amount of blue (medium) threadlocker to mounting screws.
Torque: Tighten to 15–20 in-lb (or follow the rifle manufacturer’s specification).
Level & mount: Level the action/rail, then mount and level your scope; torque rings per the ring maker’s guidance.
Confirm zero: Bore-sight, then verify at the range and build your dope card.
(Precision users sometimes lightly bed rails to maximize receiver contact—optional.)

Frequently Asked Questions
Q: Will this rail fit a Fierce Long Action?
A: No. This model is for Short Action receivers. Choose the Long Action rail for LA footprints.
Q: Do Weaver rings work on this rail?
A: Many Weaver-style rings will clamp to Picatinny, but true Picatinny rings deliver the most secure, repeatable interface.
Q: How much extra range does 20 MOA provide?
A: About 20 minutes (≈ 5.8 mils) of cant. Actual dialing potential depends on your scope’s internal elevation and your cartridge ballistics.
Q: Should I bed the base?
A: Not required for most installs. Bedding can help maximize contact on certain actions if you’re chasing ultimate precision.
Q: Are the screws included?
A: Yes—mounting screws are included. Always confirm length/thread for your exact receiver before installation.
