Summit Precision: The Foundation of Accuracy

The Summit Precision receiver is designed for tight tolerances and optimal performance. Unlike traditional blowback systems, which use gas pressure from the fired round to cycle the action, Summit’s straight-pull bolt action minimizes disruption to the round upon ignition, leading to superior accuracy. This means that the shooter manually cycles the action, reducing unwanted movement and improving shoot consistency.
| Feature | Benefit |
|---|---|
| Receiver Type | Summit Precision straight-pull bolt action |
| Accuracy | Reduced shot disturbance, improved precision |
| Operation | Smooth cycling with minimal effort |
This refined mechanism ensures a crisp and effortless cycling experience, ideal for precision shooting where consistency is key.
FNC 16" Carbon Barrel: Strength Meets Weight Reduction
The FNC 16” Carbon Barrel is engineered to provide an outstanding balance of rigidity and lightweight construction. Unlike traditional steel barrels, carbon fiber-wrapped barrels maintain strength while reducing overall weight, making the rifle easier to handle without sacrificing durability.
Carbon fiber also dissipates heat better than steel, reducing thermal drift—a phenomenon where heat causes the barrel to expand, shifting the point of impact over time.
| Feature | Benefit |
|---|---|
| Material | Carbon fiber-wrapped for strength and reduced weight |
| Heat Dissipation | Reduces thermal drift for consistent accuracy |
| Length | 16 inches for an optimal balance of precision and maneuverability |
- Ported Muzzle Compensator: This device, attached to the barrel, redirects gas from the fired round to reduce muzzle rise and recoil, allowing for faster follow-up shots and improved target acquisition.
Tandemkross: Refining the Trigger and Bolt System
A precision rifle demands a high-performance trigger and bolt assembly, and Tandemkross delivers just that.
| Component | Benefit |
|---|---|
| Manticore Trigger Assembly | Crisp, clean break with minimal travel |
| Heat Dissipation | Smooth cycling and improved reliability |
| Companion Extended Magazine Bumper | Better grip, faster reloads |
The Manticore Trigger Assembly provides a consistent, responsive trigger pull, which is crucial for precision shooting. A predictable and crisp trigger reduces shooter error, ensuring better shot placement and tighter groupings.

The KrossFire Bolt is precision-machined to minimize friction and ensure ultra-smooth cycling. This enhances feeding reliability, preventing jams and malfunctions in fast-paced shooting environments.
- Extended Magazine Bumper: Designed for better grip and easier reloads, this feature improves handling, especially in competitive shooting scenarios where speed matters.
Bringing It All Together
When combined, these components create a rifle that is greater than the sum of its parts—a 22LR precision build that balances weight, accuracy, and reliability.
The Exactus Precision Build Build is designed to deliver top-tier performance in any setting, from competition shooting to small-game hunting.
For those who appreciate the craftsmanship behind a custom build, this setup isn’t just another rimfire rifle—it’s a testament to precision engineering. Whether you’re a seasoned precision shooter or someone looking to elevate your rimfire experience, this build represents the pinnacle of performance and refinement.
