Best Red Dot for Ruger No 1 — that’s the exact question I started with when I fitted a handful of modern micro-red dots to a Ruger No. 1 single-shot rifle.
The No. 1 is a beautiful piece of kit but it wasn’t designed around Picatinny rails or mini reflex sights, so choosing a red-dot that performs well and can be mounted securely means balancing size, sight window, parallax behavior, and—crucially—mounting options.
In this guide I walk through my top picks, the real mounting reality for the No. 1, what I actually experienced on the bench and in the field, and the exact things you’ll want to check before you buy or fit a sight.

Top 5 Best Red Dot for Ruger No 1 of 2025
Aimpoint Micro T-2
The Aimpoint Micro T-2 is a compact, rugged tube-style red dot famous for outstanding battery life, proven durability, and a clean 2 MOA dot that stays on point under recoil. It’s a favorite where reliability is non-negotiable.
Product Specs (key highlights)
Battery life: thousands of hours (standard Aimpoint performance) Housing: sealed, anodized aluminum tube Weight: very light for a rugged tube red dot Controls: easy tactile buttons; multiple brightness settings My personal experience with the product
On a rifle platform the Micro T-2 feels like the gold standard for “set it and forget it.” I mounted one using a compact low-profile adapter (more on mounting below) and zeroed quickly at 50–100 yds. The sight’s dot is crisp in daylight and usable at low brightness settings in shade; I appreciated how the brightness dial is forgiving when the sun angle changes. Over multiple follow-up sessions the T-2 held zero and needed no re-adjustment beyond normal checks. Ergonomically, the tube form factor rides a bit higher than some open-reflex sights, which can actually be beneficial on a hunting rifle where you want a bit more natural cheek contact.
Online customer comments/discussions
Users consistently praise Aimpoint’s longevity and serviceability. Threads in shooter forums emphasize the Micro series’ ruggedness and long battery life; pros in those threads warn only about the cost and suggest planning for a proper mount for older lever/hinge receivers.
Mounting method (Ruger No. 1)
Requires adapter/plate. The Ruger No. 1 does not come with an integrated Picatinny rail; to fit the Micro T-2 you’ll generally use a low-profile Picatinny adapter or a Ruger-specific base that attaches to the receiver with action screws. That adapter gives you the solid platform Aimpoint needs for repeatable zero.
Trijicon MRO
The Trijicon MRO is a wide-aperture miniature reflex sight designed for fast target acquisition and a large field of view. It’s robustly built and favored by shooters who want a quick, natural sight picture without a heavy tube.
Product Specs (key highlights)
Dot/reticle: 2 MOA (other sizes available on variants) Window: large, low-profile hooded aperture Battery life: very long; efficient LED system Housing: rugged forged housing with matte finish Weight: compact and lightweight for its window size My personal experience with the product
The MRO’s big viewing window makes shooting from odd positions and quick follow-ups effortless. Mounted on a retrofitted base, the MRO gave me a broad sight picture that reduced the “tunnel vision” some tube sights produce. Zeroing was straightforward; with normal cheek weld the dot lined up intuitively. On longer shots the 2 MOA dot still allowed precise placement—especially after dialing a bit of holdover compensation at distance. The MRO’s controls are simple and the hooding helps keep glare down on bright days in open country.
Online customer comments/discussions
Feedback from rifle and AR users praises the MRO for its sight picture and durability. A common forum theme: the MRO is a great tradeoff between big-window reflexes and compact footprint, though some users prefer Aimpoint-style tube sights for absolute weather-proofing.
Mounting method (Ruger No. 1)
Requires adapter/plate. Fit the MRO to the Ruger No. 1 by installing a receiver base or a dedicated dovetail-to-Picatinny adapter (depending on your receiver configuration). Make sure the adapter uses the correct action screws for your No. 1 model.
Leupold DeltaPoint Micro
Leupold’s DeltaPoint Micro (DPM) is a small open-reflex with a super-crisp dot and an exceptionally slim profile — an excellent choice when you want minimal obstruction of the rifle’s sightline plus proven optical quality.
Product Specs (key highlights)
Reticle: 2.5 MOA dot (Leupold variants) Optical window: open reflex for wide field of view Housing: forged aluminum with protective hood Controls: tactile, easy access buttons Battery: long run time; battery placement optimized for low profile My personal experience with the product
For a light hunting rifle setup the DeltaPoint Micro felt very natural. Its low height helped me maintain a comfortable cheek weld on the No. 1 stock while still giving a bright, usable dot at dawn and dusk. The DPM is lighter than most tube sights and the dot contrast is excellent against brush backgrounds. I liked how the shielded emitter reduced stray reflections when the sun was at low angles.
Online customer comments/discussions
Many users recommend the DPM for hunters and lightweight builds. Common discussion points: excellent clarity, easy battery access, and great mounting compatibility with pistol/red dot plates adapted for rifles.
Mounting method (Ruger No. 1)
Requires adapter/plate. Most No. 1 owners will use a small footprint base or an adapter plate (RMR/DeltaPoint footprint adapters are common) secured to the receiver. If you prefer a more permanent installation, have a gunsmith fit the base to ensure proper screw torque and alignment.
Vortex Venom
The Vortex Venom is an affordable, compact reflex sight with a clean 3 MOA dot option and Vortex’s solid warranty and customer support. It’s a popular choice when budget and performance must meet.
Product Specs (key highlights)
Reticle: typically 3 MOA dot (others available) Window: frameless open reflex design Battery life: solid for its class Controls: top-mounted buttons for brightness My personal experience with the product
If you’re on a budget but still want real performance, the Venom is hard to beat. I used it on a hunting session and found target acquisition quick and intuitive. The dot is slightly larger than the 2 MOA options which can be a positive for speed but slightly less ideal for pin-point shots at longer ranges. For the No. 1, the Venom’s low mass and small footprint made mounting easier and it didn’t upset the rifle’s balance.
Online customer comments/discussions
Owners often praise Vortex’s customer service and the Venom’s value proposition. Typical forum posts note excellent clarity for the price and occasional comments about requiring a solid mount to avoid wobble on heavier recoiling platforms.
Mounting method (Ruger No. 1)
Requires adapter/plate. The Venom uses a small footprint plate; to mount it reliably on a No. 1 you’ll typically choose a dovetail or receiver base adapter that takes a mini-footprint reflex plate. Tighten to manufacturer torque specs and re-check zero after a few shots.
Burris FastFire 3
The Burris FastFire 3 is an ultra-compact reflex sight with low weight, crisp dot options, and very simple controls. It’s a go-to for those who want minimal bulk on a hunting rig.
Product Specs (key highlights)
Reticle: available 3 MOA or 8 MOA (model dependent) Housing: tiny aluminum body with protective hood Battery life: good for its form factor Weight: extremely light — excellent for traditional stocks My personal experience with the product
On a classic wood stock like the No. 1 the FastFire 3 looked almost custom-made: tiny, unobtrusive, and fast on target. The 3 MOA dot is a sweet spot for general hunting and quick shots; I had no trouble getting hits inside a few inches at 100 yd with consistent cheek weld. The small size minimizes changes to sling position and handling. Downsides are the smaller viewing window (compared to MRO) and a slightly less beefy housing than some premium reflexes — so protect it during rough handling.
Online customer comments/discussions
Many hunters and varminters love the FastFire series for its low profile and quick acquisition. Some threads caution that on heavy recoil platforms you should double-check mount stability and use a dedicated adapter plate where possible.
Mounting method (Ruger No. 1)
Requires adapter/plate. The FastFire 3 is typically mounted to an RMR/mini reflex plate or a purpose-made receiver base adapter. Because it’s light and compact, it’s particularly forgiving on the No. 1 as long as the adapter is solid and screws are torqued correctly.
Why You Should Trust My Review
I’ve fitted and shot each of these optics on bolt-action and single-shot hunting rifles, including multiple sessions on the Ruger No. 1 platform. I approach testing as a working hunter/shooter: I evaluate zero retention, ergonomics with a full cheek weld, sight picture clarity across common field distances (10–300 yd), and real mounting practicality for receivers that don’t have factory rails. I also cross-checked owner reports across several shooting communities and compared repeated user feedback on mounting solutions. This isn’t just spec-reading—these are optics I’ve had on the bench and behind the rifle, verified under realistic conditions.
How I Tested These Sights
My testing protocol combines bench and field steps to simulate real use:
Mounting & Fit: I installed each optic using an appropriate adapter or base for the Ruger No. 1 and checked fit, clearance, and repeatable seating. If the adapter required gunsmith fitting I noted that. Initial Zero: Zero at 50 yds (where feasible) for quick verification, then confirm at 100 yds to assess point-of-impact shift. Zero Retention Test: After establishing zero, I fired a cold-to-hot string of shots and rechecked zero after 25 rounds and then again after 50 rounds to watch for drift. Ergonomics & Speed: Quick acquisition drills at close and mid distances, shooting lying/prone/kneeling/standing to see how natural the cheek weld and sight height felt. Environmental Checks: Observed dot visibility in bright sun, shade, and low light. Also checked controls with gloved hands. Real-World Follow Up: Field sessions in brush/woodland conditions to verify sight picture and retention under typical hunting movement. I repeated the above on multiple rifles to differentiate optic behavior from rifle quirks.
FAQs
Q1: What is the Best Red Dot for Ruger No 1?
A1: The right pick depends on your priorities: if you want rugged, long-term reliability choose the Aimpoint Micro T-2; for a large, fast window choose the Trijicon MRO; for a minimal, low-profile install the Leupold DeltaPoint Micro or Burris FastFire 3. All of my top picks above will work well, provided you use a proper receiver base or adapter to mount them securely.
Q2: Can I mount a red dot directly to my Ruger No. 1 without a gunsmith?
A2: Most No. 1 rifles don’t have a factory Picatinny rail; many owners fit a receiver-specific base or a dovetail adapter. If you’re comfortable with hand tools and the adapter is a simple screw-on base that matches your receiver’s screw pattern, you can do it at home. For permanent or cut-and-fit bases, a gunsmith is recommended.
Q3: Will a 2 MOA dot work for hunting with a Ruger No. 1?
A3: Yes. A 2 MOA dot is a good compromise—small enough for precise hits at 100+ yards, yet quick for close shots. If you expect very close shots only, a 3 or 4 MOA dot speeds target acquisition; for long, precise shots, consider pairing the dot with known holdovers or a magnifier.
Q4: Do I need to worry about recoil on the No. 1 with these micro-dots?
A4: As long as the mount is solid and torqued correctly, modern micro-dots (Aimpoint, Trijicon, Leupold, Burris, Vortex) handle typical hunting-rifle recoil without issue. The weak link is usually the adapter or improperly seated screws, not the optic itself.
Q5: Which footprint should I choose for a Ruger No. 1 adapter plate?
A5: Choose a plate that accommodates the footprint of your chosen optic (RMR, DeltaPoint, Aimpoint Micro, or universal Picatinny). Many aftermarket bases are made specifically to accept Aimpoint-style micro rails or RMR/DPM footprints. Match the plate to the optic to minimize adapters and stacking tolerances.
Conclusion
Choosing the Best Red Dot for Ruger No 1 comes down to matching a sight’s physical footprint and performance to the No. 1’s receiver and intended use. If you want rock-solid reliability and minimal fuss, Aimpoint Micro T-2 is an outstanding—but pricier—option. If speed and a wide field are your priority, the Trijicon MRO shines. For minimal weight and a slim profile the Leupold DeltaPoint Micro and Burris FastFire 3 are smart, lighter choices, while the Vortex Venom gives great value for money. Whichever route you take, plan for a proper adapter or receiver base, verify your screw pattern, torque everything to spec, and confirm zero after a small follow-up string of shots—those steps are the difference between a red dot that works and one that merely looks good on the rifle.
