Description
Talley built this Fierce Rivalry Picatinny rail to do one thing really well: give your short-action Fierce Rival a dead-nuts stable optic base with a little extra elevation baked in. The 20 MOA cant tilts your scope forward so you keep more usable adjustment in the turret when you're reaching out past where a flat base runs out of room. If long-range work is on the menu, that built-in slope is the difference between dialing confidently and running out of clicks.
What Makes the Fierce Rivalry Rail Hold Zero
This rail is machined entirely from high-grade 7000-series aircraft aluminum and finished with a hard-coat anodize rated to 65 Rockwell, so it shrugs off the knocks and weather that come with real hunting and range use. It runs on the MIL-STD-1913 Picatinny spec, meaning any rings or mounts cut to that standard will clamp on and index correctly, including Talley's own Picatinny rings. The whole thing is made in America and cut to tight tolerances so it sits flush and true on the receiver.
Fitment and Getting the Rail Mounted
The Short Action version measures 6.28 inches and is designed specifically for the Fierce Rival series receiver. Talley includes the mounting hardware in the box, so you get 8-40 screws and a T15 wrench to set it up without a trip to the parts drawer. One tip from experience: use a calibrated torque wrench and confirm the receiver's allowable torque with Fierce before you crank down, since over-torquing into an action is a good way to cause trouble.
Why the 20 MOA Cant Matters
A 20 MOA rail isn't just for benchrest crowds. Even if you spend most of your time inside 300 yards, the extra elevation range means your optic isn't fighting to reach zero, and you keep a healthy cushion of turret travel for when you do stretch it out. For a precision-minded Fierce Rival build, this is the kind of base that quietly does its job and lets the rifle shoot to its potential.

Frequently Asked Questions
What rifles does the Fierce Rivalry Picatinny Rail fit?
This Short Action version is engineered specifically for the Fierce Rival series receiver and measures 6.28 inches. If you have a 6.5 PRC or another cartridge that could be built on either action, double-check your action length with Fierce before ordering so you get the right base.
Why choose a 20 MOA rail instead of a flat one?
The 20 MOA cant tilts the optic slightly forward, which gives you more usable elevation travel in your scope's turret for reaching longer distances. Even for shooting inside a few hundred yards, it leaves you plenty of adjustment cushion so your optic isn't maxed out trying to hit zero.
Does the rail come with everything I need to install it?
Yes, Talley includes the 8-40 mounting screws and a T15 wrench in the box. You'll want a calibrated torque wrench on hand, and it's smart to verify the receiver's allowable torque with Fierce before tightening down to avoid over-torquing the action.
Will my scope rings work with this Talley rail?
Any rings or mounts built to the MIL-STD-1913 Picatinny standard will clamp on and index properly, including Talley's own Picatinny scope rings. That gives you a lot of freedom to run whatever quality rings match your optic's tube diameter and height needs.
