Top 6 Best Red Dot for Archon Type B Gen 2 in 2026

The Archon Type B Gen 2 is the kind of pistol that rewards a clean, fast sighting system. Its low-bore-axis feel, crisp recoil impulse, and duty-style ergonomics make it a strong host for a pistol red dot, but only if the optic is durable, easy to track, and realistic to mount.

For this guide, I focused on compact and full-size pistol optics that make sense on an Archon Type B Gen 2 slide. My priorities were durability, window size, dot clarity, battery access, recoil resistance, and how easily the optic can be mounted with the correct adapter plate or gunsmith-cut slide. I also paid close attention to what shooters usually complain about online: tiny windows, awkward controls, short battery life, and mounting confusion.

Quick Summary

My top overall pick is the Trijicon RMR Type 2 because it is the proven hard-use choice for a defensive Archon Type B Gen 2 setup. The HOLOSUN 507C-X2 is the best value because it gives me multiple reticle options, solar backup, and a very usable window without jumping into premium pricing. For shooters who want an enclosed emitter, the Aimpoint ACRO P-2 is the strongest rugged option, while the HOLOSUN 509T gives a more feature-rich enclosed alternative.

Top 6 Best Red Dot for Archon Type B Gen 2 in 2026

Trijicon RMR Type 2


Trijicon RMR Type 2

The Trijicon RMR Type 2 is my first choice when I want a no-nonsense red dot on an Archon Type B Gen 2. It is compact, battle-proven, and built for pistols that may be carried, trained with hard, or used defensively.

  • Open-emitter reflex sight

  • RMR footprint

  • Adjustable LED brightness

  • Rugged forged-style housing design

  • Commonly used on duty and defensive handguns

  • Best suited for carry, range training, and home-defense setups

Pros

  • Excellent durability

  • Very strong aftermarket plate support

  • Compact enough for a pistol slide

  • Clear dot with dependable brightness settings

  • Proven track record under recoil and hard use

Cons

  • Smaller window than some newer optics

  • Battery access usually requires optic removal

  • Premium price

  • No enclosed emitter protection

My personal experience with the product

When I run an RMR-style optic, I immediately notice how natural it feels on a defensive pistol. The window is not huge, but the shape helps me index the dot consistently after recoil. On an Archon Type B Gen 2, I like the RMR Type 2 because it keeps the pistol balanced and does not make the slide feel overly bulky. For serious carry or defensive work, this is the optic I trust most.

Summary of online customer feedback

Most customer feedback centers on durability, reliability, and confidence. Shooters like that the RMR Type 2 feels nearly bombproof compared with many open-emitter optics. The most common complaints are the price and the bottom-loading battery design, but many users still accept those tradeoffs because the optic has such a strong reputation.

Mounting explanation

The Trijicon RMR Type 2 does not simply mount directly to a standard, non-optics-cut Archon Type B Gen 2 slide. It requires either a slide cut for the RMR footprint or a compatible adapter/mounting plate if the pistol is using an optics-ready mounting system. I would confirm the exact Archon Type B Gen 2 slide configuration before ordering the optic or plate.

HOLOSUN 507C-X2


HOLOSUN 507C-X2

The HOLOSUN 507C-X2 is the optic I recommend when someone wants a strong balance of price, features, and real-world usability. It gives the Archon Type B Gen 2 a modern pistol-dot setup without feeling like a compromise.

  • Open-emitter reflex sight

  • RMR-style footprint

  • Multi-reticle system

  • Solar backup

  • Side battery tray

  • Shake-awake style operation

  • Best suited for range, carry, and general-purpose use

Pros

  • Excellent feature set for the money

  • Side battery tray is convenient

  • Multiple reticle choices

  • Good window size for fast acquisition

  • Strong plate compatibility

Cons

  • Not as physically rugged as the hardest-use premium optics

  • Open emitter can collect lint, water, or debris

  • Reticle options may feel busy to some shooters

  • Buttons are small with gloves

My personal experience with the product

I like the 507C-X2 because it is easy to live with. The reticle options make it beginner-friendly, especially if someone is still learning to find the dot during presentation. On my pistols, I usually start with the circle-dot reticle for speed, then switch to the dot-only mode once my draw stroke is cleaner. On the Archon Type B Gen 2, that flexibility makes a lot of sense.

Summary of online customer feedback

Customers often praise the 507C-X2 for value, battery convenience, and reticle versatility. Many shooters say it gives them most of what they want from a premium optic at a more approachable price. Negative feedback usually involves personal preference around the reticle system or concerns that an open-emitter optic is less protected than an enclosed design.

Mounting explanation

The HOLOSUN 507C-X2 uses an RMR-style footprint, so it will usually require an RMR-compatible adapter plate or a direct RMR slide cut. It does not mount directly to a plain Archon Type B Gen 2 slide unless that slide has already been cut for the optic footprint.

Aimpoint ACRO P-2


Aimpoint ACRO P-2

The Aimpoint ACRO P-2 is my pick for a serious enclosed-emitter setup. If the Archon Type B Gen 2 is being configured as a hard-use pistol, the ACRO P-2 brings a level of environmental protection that open-emitter optics cannot match.

  • Enclosed-emitter pistol red dot

  • ACRO-style mounting footprint

  • Rugged sealed housing

  • Long battery life design

  • Compact duty-oriented profile

  • Best suited for duty, carry, adverse weather, and defensive use

Pros

  • Fully enclosed emitter

  • Extremely rugged build

  • Excellent for rain, dust, lint, and debris

  • Strong duty reputation

  • Simple, clean dot presentation

Cons

  • Expensive

  • Bulkier than open-emitter micro dots

  • Requires the correct ACRO-compatible plate

  • Smaller apparent window than some competition-style optics

My personal experience with the product

The ACRO P-2 feels different from open reflex sights because the housing is more like a small sealed tube. At first, that can look boxy on a pistol, but I quickly appreciate it when shooting in messy conditions. On an Archon Type B Gen 2, I would choose this optic if reliability in rain, dust, sweat, and daily carry debris mattered more than having the largest possible window.

Summary of online customer feedback

Online feedback is usually very positive from duty-minded shooters. People like the sealed emitter, ruggedness, and Aimpoint reputation. The most common complaints are cost, size, and the need for a specific mounting solution. Still, many users see it as one of the best choices for a pistol that may be carried every day.

Mounting explanation

The Aimpoint ACRO P-2 requires an ACRO-compatible mounting plate or a slide cut specifically for the ACRO footprint. It does not mount directly to an RMR, DeltaPoint Pro, or RMSc cut without the proper adapter system. For the Archon Type B Gen 2, I would verify plate availability before buying.

HOLOSUN 509T


HOLOSUN 509T

The HOLOSUN 509T is the enclosed optic I like when I want protection from the elements but still want Holosun-style features. It is a strong match for an Archon Type B Gen 2 that will see carry, training, and all-weather range use.

  • Enclosed-emitter reflex sight

  • 509T-style mounting system

  • Multi-reticle system

  • Solar backup

  • Side battery access

  • Titanium-style rugged design concept

  • Best suited for enclosed-emitter value and feature balance

Pros

  • Enclosed emitter protects the dot system

  • Multiple reticle choices

  • Good battery access

  • Strong feature set

  • More weather-resistant than open-emitter optics

Cons

  • Requires a specific plate or adapter

  • Sits taller than many open reflex sights

  • Reticle system may be more than some shooters need

  • Window feels more enclosed than a large open optic

My personal experience with the product

The 509T gives me confidence when I am not babying the pistol. I like that dirt, lint, and rain are less likely to block the emitter compared with an open optic. On the Archon Type B Gen 2, I would use the 509T for a practical defensive build where I still want the convenience of modern reticle and battery features.

Summary of online customer feedback

Customer feedback often praises the 509T for combining enclosed-emitter protection with Holosun’s feature set. Shooters like the reticle options, battery convenience, and rugged feel. The main negative comments usually involve mounting height, adapter complexity, and the fact that it is not as universally simple to mount as an RMR-footprint optic.

Mounting explanation

The HOLOSUN 509T needs its own compatible mounting setup. It does not directly share the same footprint as the HOLOSUN 507C-X2 or Trijicon RMR Type 2. For an Archon Type B Gen 2, it will require a compatible 509T plate, adapter, or custom slide cut.

Leupold Deltapoint Pro


Leupold Deltapoint Pro

The Leupold Deltapoint Pro is the red dot I would choose for shooters who want a generous window and fast visual pickup. It feels especially good during range work, transitions, and speed-focused pistol shooting.

  • Open-emitter reflex sight

  • DeltaPoint Pro footprint

  • Large viewing window

  • Top battery access

  • Motion-activation style operation

  • Best suited for fast acquisition and range use

Pros

  • Large, easy-to-find window

  • Very fast sight picture

  • Top-loading battery is convenient

  • Good optical clarity

  • Comfortable for newer dot shooters

Cons

  • Taller than some compact pistol optics

  • Open emitter is exposed

  • Requires the correct footprint or plate

  • Not as compact as the RMR Type 2

My personal experience with the product

The Deltapoint Pro feels fast. When I bring the pistol up from the holster, the larger window gives me a little more forgiveness if my presentation is not perfect. On the Archon Type B Gen 2, I like it most for range training, competition-style drills, and shooters who prioritize speed over maximum compactness.

Summary of online customer feedback

Many shooters praise the Deltapoint Pro for its window size, clarity, and easy battery access. It is often recommended for people who struggle to find the dot on smaller optics. Criticism usually focuses on height, bulk, and the fact that it is not enclosed.

Mounting explanation

The Leupold Deltapoint Pro uses the DeltaPoint Pro footprint, so it needs a compatible plate or slide cut. It will not mount directly to an RMR-pattern Archon Type B Gen 2 setup unless the mounting system includes the proper adapter.

Steiner MPS


Steiner MPS

The Steiner MPS is a compact enclosed-emitter optic that makes sense for shooters who want a rugged tactical red dot without going too large. It gives the Archon Type B Gen 2 a tough, squared-off profile and strong protection from weather and debris.

  • Enclosed-emitter pistol red dot

  • Compact tactical housing

  • Sealed emitter system

  • Adjustable brightness

  • Durable duty-style construction

  • Best suited for compact enclosed tactical use

Pros

  • Enclosed emitter design

  • Rugged compact body

  • Good option for harsh conditions

  • Clean dot presentation

  • Strong tactical feel

Cons

  • Requires the correct mounting plate

  • More blocky than open-emitter optics

  • Not as common as RMR-footprint options

  • May sit higher depending on plate setup

My personal experience with the product

The MPS feels like a serious-use optic. It is compact, solid, and less bulky than some enclosed designs, which I appreciate on a pistol like the Archon Type B Gen 2. I would choose it for a defensive build where I want an enclosed emitter but do not necessarily want the ACRO P-2’s price or profile.

Summary of online customer feedback

Shooters often like the Steiner MPS for its rugged sealed design and compact duty-oriented shape. Positive feedback usually mentions durability and confidence in rough use. Complaints tend to focus on plate compatibility, mounting height, and the fact that fewer people have long-term experience with it compared with the RMR or ACRO.

Mounting explanation

The Steiner MPS requires a compatible mounting plate or slide cut. It does not directly mount to a standard Archon Type B Gen 2 slide without an optics mounting solution. Before choosing it, I would make sure the required plate is available for the pistol’s exact slide system.

How to Choose the Right Red Dot Sight

When choosing a red dot for the Archon Type B Gen 2, I start with the mounting system. This pistol is not like buying a generic optic-ready Glock plate and calling it done. I want to confirm whether the slide is already optics-ready, whether it uses adapter plates, or whether it needs a custom slide cut. The footprint matters more than almost anything else.

For defensive use, I lean toward the Trijicon RMR Type 2, Aimpoint ACRO P-2, HOLOSUN 509T, or Steiner MPS. These are the optics I would consider first when durability and reliability matter most. The RMR Type 2 is the easiest recommendation for a proven open-emitter setup, while the ACRO P-2, 509T, and MPS make more sense if I want an enclosed emitter.

For range and training, window size becomes more important. The Leupold Deltapoint Pro is easier to pick up quickly because the viewing window is generous. That makes it friendly for newer red-dot shooters or anyone who wants a faster visual reference during transitions.

Battery access is another detail I do not ignore. Side-loading and top-loading batteries are easier to live with because I do not have to remove the optic and potentially re-zero it. That is one reason I like the HOLOSUN 507C-X2 and Leupold Deltapoint Pro for regular range use.

Finally, I match the optic to the pistol’s role. For concealed carry, I prefer compact and rugged. For home defense, I like a bright, simple dot with dependable controls. For training and speed work, I want a bigger window. For duty-style use, I strongly consider enclosed emitters.
