Out of the Box
Springfield ships the Heatseeker with a soft-sided rifle case. This is a small but appreciated touch, especially when most rifles just come in a cardboard box. It comes with a single 5-round mag, a gun lock, a sticker, and a warranty card. Right from the factory, the rifle feels solid and well-balanced. The coyote brown Cerakote finish gives the rifle a field-ready look, while the minimalist chassis design keeps the weight down and makes it easy to carry afield.
Stock
The Sharps Bros Heatseeker Chassis is built from a single block of 6061-T6 aluminum and weighs just over a pound. It mates perfectly with the Model 2020 action and accepts standard AR buffer tubes and pistol grips. The B5 Systems Collapsible Precision Stock stood out to me with its adjustable cheekpiece and length-of-pull. That feature was invaluable when switching between daytime optics and a thermal scope on a QD mount. It allowed me to make quick changes while always maintaining the perfect position on the rifle.
While I’m a big fan of the adjustability, I do wish the stock folded. At this price point, a folding mechanism would go a long way in improving portability, especially for hunters packing into remote locations. Since the rifle doesn’t use an anti-rotation plate, there aren’t many drop-in options for folding stock conversions either.
Handguard on the Heatseeker
The handguard on the Heatseeker strikes a unique balance between function and minimalism. M-LOK slots at multiple positions allow for mounting bipods, slings, and lights, while the skeletal cutouts reduce weight and give you additional thumb clearance under the optic.
It’s comfortable to grip and maneuver, but the thinner profile and lack of a flat bottom do limit its effectiveness for positional shooting. It’s not the most rigid for running a front-mounted clip-on thermal or NV device. Still, for hunting and general precision shooting, it offers plenty of utility.
Action
At the heart of the Heatseeker is Springfield’s Model 2020 action. It is machined with dual locking lugs, a fluted bolt, and EDM-cut raceways. The bolt has just a touch of play, but it cycles great and reliably. Even when I ran it hard and off-angle during faster follow-up shots, it never bound up or failed to feed. I shot it a decent amount out in the wind and dust, but even with the grit buildup, the action powered through.
Trigger
This rifle ships with a Triggertech Field Trigger, and it lives up to the reputation. I’m a big fan of Triggertechs in general, and this device continues to impress. There’s no take-up, and it breaks cleanly right past the wall. From the factory, mine measured 3.5 lbs, but it’s user-adjustable from 2.5 to 5.0 lbs in 1-ounce increments.
In a precision or hunting setup, the trigger is one of the most important user interfaces, and Springfield nailed it using this trigger. No gritty pull, no mush past the wall, just a clean break every time.
Magazines
The Heatseeker comes with a single 5-round AICS-pattern mag, but I spent most of my time with 12-round MDT mags. These larger mags gave me more flexibility on the range and in the field. AICS compatibility is a major win, as it opens up a massive aftermarket of proven, reliable options.
The mags seated firmly and dropped free without issue. Feeding was consistent, and the magazine release location worked well without ever being bumped accidentally.
Barrel
The BSF 16” barrel is carbon fiber-wrapped, featuring a roll-wrapped tensioned sleeve. This improves cooling, reduces weight, and maintains rigidity. The barrel is threaded 5/8×24 and comes with a thread protector installed. I ran this rifle suppressed using a SilencerCo Hybrid 46, and it ran and sounded great.

Accuracy is a big part of the Heatseeker’s pitch, and Springfield backs it up with a .75 MOA guarantee for 3-shot groups using match-grade ammo. While my test rifle didn’t hit that mark with every load I tried, it did with Federal Gold Medal Match 168gr BTHP, averaging 0.76 MOA. Results with other loads were more mixed, but I suspect some bad lots of Hornady may have influenced those numbers. Not sure if I had the ammo sitting in my garage for too long or what. Either way, the rifle shows serious potential when paired with the right ammo.
Here are the average group sizes and best groups I recorded during testing:
| Ammunition Type | Average Velocity (FPS) | Avg 3-Round Group Size (MOA) | Best 3-Round Group Size (MOA) |
| Federal Gold Medal Match 168gr BTHP | -not tested- | 0.76 | 0.65 |
| Hornady American Whitetail 150gr InterLock | 2569 | 0.97 | 0.89 |
| Hornady Black 155gr A-MAX | 2662 | 2.03 | 1.40 |
| Hornady Match 168gr BTHP | 2486 | 1.28 | 1.21 |
| Hornady SuperPerformance 168gr ELD Match | 2653 | 3.35 | 2.91 |
| Hornady Precision Hunter 178gr ELD-X | 2459 | 2.14 | 1.97 |
Performance
The Heatseeker handles like a purpose-built hybrid. It isn’t a PRS race gun, and it isn’t a featherweight mountain rifle. Instead, it’s a do-it-all platform that works well for shooters who want a compact, accurate chassis rifle with hunting and modularity in mind.
Running this rifle suppressed made for a comfortable shooting experience. The short barrel paired with my can made transitions quick, and the recoil was manageable for fast follow-ups. The collapsible stock let me fine-tune my cheek weld for either a traditional scope or my thermal in no time. This was especially nice for nighttime hog and coyote control efforts.
Accuracy with match-grade ammo was solid, though I would’ve liked to see tighter groups across a broader range of loads. Still, the rifle delivered on its .75 MOA guarantee with at least one factory option. After getting subpar results from several Hornady loads, I considered sending the rifle in for warranty evaluation and reached out to the Springfield team. They responded by sharing that, prior to shipping, they had proof-tested this exact rifle with Federal Gold Medal Match 168 grain and recorded sub-.75 MOA groups. That level of transparency and the fact that they proof test each rifle before shipping it out the door was impressive. It also prompted me to try the same load, and sure enough, I immediately achieved sub-.75 MOA results as well. With the right ammunition, I believe the Heatseeker is capable of even better consistency.

Heatseeker Summary
The Springfield Armory Model 2020 Heatseeker hits a sweet spot between modular adaptability and precision performance. It’s built around a smooth, reliable action, sports a fantastic Triggertech trigger, and comes in a lightweight chassis system that supports AR-style furniture. The .75 MOA guarantee is a welcome benchmark in today’s market, and the rifle shows clear potential with quality ammunition.
For $2,355 MSRP, it’s priced among serious competition, but it brings enough unique features to justify consideration. While I’d like to see a folding stock at this price point, the overall package is still strong. Especially for shooters who want something compact, modular, and suppressor-ready. The Heatseeker isn’t necessarily a competition rifle, and it’s not a lightweight mountain rifle either, but it blends enough from both to make it a compelling all-around bolt gun for the modern shooter.
