Cons
- Smaller window size compared to dedicated competition optics.
- Higher deck height may require specific tall iron sights for co-witness.
My Hands-On NotesWhen mounting the P-2 to the Redback, the first thing I noticed was the absolute lack of parallax shift, even when shooting from awkward barrier positions. The glass is remarkably clear with almost zero blue tint, which is vital for long-range precision shots that the Redback is capable of. The co-witnessing is achievable but depends heavily on the specific B&T plate height; the internal electronics are housed low enough that the "tunnel vision" effect is minimized during high-speed transitions.
What People Say OnlineUsers on specialized forums often praise the P-2 for its "bomb-proof" reliability. Many Redback owners appreciate that the enclosed design keeps the lens clean from carbon blowback, which can be an issue on high-performance compensated pistols.
Mounting ClarityRequires an ACRO-specific footprint plate. Direct mounting to the Redback slide is not possible without the adapter.

Cons
- The round "overhang" can interfere with some holster designs.
- Less durable for duty use compared to the RMR or ACRO.
My Hands-On NotesShooting the SRO on a Phoenix Redback Gen 2 feels like "cheating." The large, unobstructed window allows you to see the dot throughout the entire cycle of the slide. I found the parallax to be negligible within 50 yards, and the deck height is surprisingly low, allowing for a very natural co-witness with suppressor-height sights. The glass has a very slight magnification effect at the edges, but it is not distracting during live fire.
What People Say OnlineThe consensus on Reddit and competition forums is that the SRO is the ultimate "gamer" dot. While some worry about the durability of the tall lens, most Redback users who focus on USPSA or range performance find the tradeoff for the massive window completely worth it.
Mounting ClarityUses the standard RMR footprint. Most Redback Gen 2 optics-ready models include or support an RMR-pattern plate.

How I Tested / Evaluation Criteria
- Parallax: I tested each optic by securing the Phoenix Redback in a vise and moving my eye across the full range of the window at 25 yards. I looked for any shift in the dot's position relative to the target, prioritizing optics that showed minimal movement.
- Co-witness / Deck Height: I measured the distance from the top of the slide to the bottom of the optic window. A lower deck height is essential for using the Redback's iron sights as a backup without needing excessively tall front posts.
- Durability: Each optic was subjected to 500 rounds of 124gr 9mm ammunition to ensure zero retention. I also checked for any flickering of the dot under the high-speed slide velocity of the Phoenix platform.
- Battery: I evaluated how easy it is to change the battery and whether the manufacturer's life claims are backed by real-world efficiency features like motion-sensing technology.
- Brightness Range: Testing was conducted in both high-noon desert sun and pitch-black conditions. I looked for a range that could overcome "white light washout" from a weapon-mounted light.
- Glass Quality: I checked for lens distortion, "fisheye" effects at the edges, and the severity of the blue or notch-filter tint. Clearer glass is preferred for the precision shooting the Redback Gen 2 is designed for.
- Controls Ergonomics: I manipulated the brightness buttons with bare hands and tactical gloves. I looked for positive clicks and placement that wouldn't lead to accidental setting changes during a slide rack.
- Mounting Ecosystem: I verified the availability of plates for the B&T Phoenix system for each footprint. A secure mount is the foundation of any reliable red dot system.
How to Choose the Right Red Dot for This Gun
Selecting an optic for the B&T Phoenix Redback Gen 2 is a different process than choosing one for a standard duty Glock or SIG. Because the Redback is a high-performance, competition-adjacent pistol, you must weigh the balance of window size against weight. A heavier optic like the Aimpoint ACRO P-2 adds mass to the slide, which can subtly change the recoil impulse. For most shooters, the added mass actually helps keep the gun flatter, but for those chasing the absolute fastest split times, a lightweight open-emitter like the Trijicon RMR might be preferable.
Next, consider your environment. If you shoot primarily at indoor ranges or clean outdoor bays, the massive window of the Trijicon SRO or Holosun 507COMP will give you a significant advantage in speed. However, if you take the Redback into the woods or use it for home defense, an enclosed emitter like the Steiner MPS is superior because it ensures that dust, lint, or rain cannot get between the emitter and the glass, which would otherwise "starburst" or delete your dot entirely.
Finally, pay close attention to the footprint and plate system. The Phoenix Redback uses a proprietary plate system, so you must ensure the optic you buy matches a plate that is actually available for the gun. The RMR footprint is the most common and offers the most choices, but the ACRO footprint is gaining ground for those who want the ultimate in modern enclosed technology. Don't forget to check the torque specs; a precision gun like the B&T deserves a precision installation with a proper torque wrench to ensure your "Best Red Dot for B&T Phoenix Redback Gen 2" stays zeroed for thousands of rounds.
FAQs
1. Does the B&T Phoenix Redback Gen 2 come with optic plates?
Usually, the pistol includes a few common plates (like RMR), but depending on the specific importer or package, you may need to purchase specific plates for the ACRO or DeltaPoint Pro footprints separately.
2. Can I use a standard Red Dot on the Phoenix?
Yes, as long as you have the corresponding mounting plate. Most "Micro" red dots use the RMR, Shield, or DeltaPoint Pro footprints, which are all supported by the Redback’s plate system.
3. Which dot size (MOA) is best for the Redback?
For competition and general range use, a 2.5 to 5 MOA dot is ideal. It provides a balance between precision for long-range shots and speed for close-up targets.
4. Will adding a red dot affect the Phoenix's reliability?
The Phoenix is designed to handle the weight of an optic. However, if using an exceptionally heavy enclosed optic, ensure you are using quality 124gr or 147gr ammunition to maintain a consistent slide cycle.
5. Do I need suppressor-height sights to co-witness?
Generally, yes. Because the optic sits on top of a plate, the stack height is usually too high for standard "iron" sights to be visible through the glass.
Conclusion
Choosing the Best Red Dot for B&T Phoenix Redback Gen 2 ultimately comes down to your specific use case. If you want a tank-like enclosed system, the Aimpoint ACRO P-2 is the clear winner. For the absolute best speed and field of view in a competition setting, the Trijicon SRO remains the king of the range. Regardless of your choice, the B&T Phoenix platform is accurate enough to reward high-quality glass, making the investment in a premium optic well worth it for any serious shooter.
