Why Upgrade Your Ruger Precision Rimfire to the Heatseeker
Rigid Aluminum Precision
The Heatseeker’s monolithic aluminum chassis resists flex and temperature shifts, providing repeatable bedding and consistent action screw torque—critical for rimfire platforms where ammo variance magnifies any stock movement.
Free-Float M-LOK Forend
Keep sling/bipod load off the barrel to preserve zero. Add exactly what you need—bipods, Arca plates, QD sling cups, barricade stops, cable management, lights, data boards—with clean indexing on flat facets and generous M-LOK slots.
Durable Black Cerakote
The low-glare finish shrugs off moisture, mud, and range rash, acting like armor for truck racks, match barricades, and wet weather.
Competition-Ready Ergonomics
A squared forend and straight recoil path help you drive the rifle on bags and barricades. The modern grip angle and stock geometry aid natural head position for scope height consistency.
Trainer to Hunter Flexibility
The rigid free-float platform pairs perfectly with threaded barrels, tuners, and suppressors, letting you mirror your centerfire setup and build confidence without burning out your big-gun barrel.
Field-Ready Feature Set
Drop-in chassis solution for Ruger Precision Rimfire
Free-float forend prevents pressure on the barrel channel
M-LOK® at 3/6/9 o’clock for universal accessory mounting
Black Cerakote finish for weather and wear protection
Lightweight aluminum balances trail carry and match stability

Compatibility note: Designed for RPR Rimfire receivers. If your rifle uses non-standard barrels, oversized tuners, or unique bottom configurations, verify clearances and inlet dimensions before purchase.
Perfect For
NRL22 / Rimfire PRS: Free-float stability, M-LOK flexibility, and repeatable torque for tiny groups on the clock.
Small-Game & Pest Control: Lightweight, rigid accuracy with sling and bipod mounting exactly where you want them.
Training & Youth Rifles: Modern ergonomics and modularity that grow with the shooter.
Suppressed Trainers: Plenty of forend clearance for threaded barrels, tuners, and cans.
Installation Overview (Quick Plan)
Clear & Disassemble: Verify the rifle is unloaded; remove the bolt and factory stock per Ruger’s manual.
Seat the Receiver: Place the barreled action into the Heatseeker chassis, ensuring proper recoil lug and magazine well alignment.
Torque to Spec: Tighten action screws with an inch-pound torque wrench to manufacturer-recommended values (record them for future consistency).
Function Check: Confirm magazine insertion/ejection, safety, bolt travel, and trigger operation.
Zero & Validate: Re-zero your optic and confirm POI stability from bags, bipod, tripod clamps, and barricades.
Pro Setup Tips
Torque Consistency: Rimfires are sensitive—log your final torque so you can repeat it after deep cleans or transport.
Balance Matters: Use M-LOK to place a bipod or Arca rail at the rifle’s balance point for smoother transitions.
Sling Smart: Add M-LOK QD cups fore and aft to keep the rifle tight against the body during long stages or hikes.
Clearance Check: Verify full clearance with bull barrels, barrel tuners, and suppressors to preserve the free-float benefit.
Ammo Testing: Try several rimfire loads; the chassis gives you a stable baseline to identify what your barrel truly prefers.
Frequently Asked Questions
Q: Will this fit all Ruger Precision Rimfire models?
A: It’s built for the RPR Rimfire platform. If you run oversized barrels/tuners or unique aftermarket components, confirm dimensions for proper clearance.
Q: Do I need bedding?
A: Most users see great results with a true drop-in install. For ultimate precision, ensure proper torque; bed only if your specific setup calls for it.
Q: Can I attach a bipod, sling, and Arca plate?
A: Yes. The M-LOK forend accepts direct-mount bipods or rails, QD sling cups, and Arca Swiss plates for tripod or barricade work.
Q: Will it improve accuracy?
A: Barrels and ammo set the ceiling, but rigidity + free-float + repeatable torque typically yield more consistent groups and better positional performance.
Q: Is the finish durable?
A: Cerakote provides excellent abrasion and corrosion resistance for daily training, matches, and foul-weather hunts.
