The 6 Best Red Dot Sight for Bul Armory AXE is an optics-ready pistol platform that can benefit significantly from a quality red dot sight. A pistol-mounted optic provides a visible aiming point that can make target acquisition more intuitive while giving the shooter a clear reference point during practice and competition.
However, choosing the right optic requires more than simply selecting a popular red dot. Footprint compatibility, window size, durability, reticle design, battery system, and overall dimensions all deserve attention.
The 6 Best Red Dot Sight for Bul Armory AXE can be configured with different optics plates depending on the specific model and setup. This makes footprint verification especially important before purchasing a sight. Several of the optics in this guide use the widely supported RMR footprint, while the Leupold DeltaPoint Pro uses a different mounting pattern. Always confirm the plate supplied with your particular AXE before ordering an optic.
6 Best Red Dot Sight for Bul Armory AXE
For this guide, we have selected the 6 Best Red Dot Sight for Bul Armory AXE covering different priorities.
1. Holosun HS507C X2 2 MOA Dot & 32 MOA Circle
The Holosun HS507C X2 2 MOA Dot & 32 MOA Circle is a versatile open reflex sight that fits well with the role of an optics-ready pistol such as the BUL Armory AXE. Its Multi-Reticle System allows the user to select a 2 MOA dot, a 32 MOA circle, or a combination of the two. This gives the shooter flexibility to choose a reticle that suits different shooting conditions and preferences. Holosun lists the sight as using the RMR footprint.
One of the biggest attractions of the HS507C X2 is its combination of electronic features. It incorporates Shake Awake technology, which activates the optic when movement is detected, while Solar Failsafe provides an additional power source under suitable lighting conditions. The sight also has manual brightness controls and lockout functionality to help prevent unintended changes to the settings.
The 2 MOA dot provides a relatively precise aiming point, while the 32 MOA circle can make the reticle easier to acquire quickly. Shooters who prefer a simple aiming point can use the dot by itself, while those who want a more prominent aiming reference can select the circle-dot configuration. This flexibility makes the optic suitable for different shooting styles.
Battery management is another useful feature. The HS507C X2 uses a side-loading CR1632 battery, meaning the battery can be replaced without removing the optic from the slide. Holosun specifies up to 50,000 hours of battery life at setting 6, although actual battery life varies according to brightness and operating conditions.
The optic has a 7075-T6 aluminum housing, an IP67 rating, a 1x magnification, and a 0.91 × 0.63-inch window. Its combination of a flexible reticle, compact construction, solar backup, and RMR compatibility makes it a strong all-around option for the BUL Armory AXE.

2. Trijicon RMR Type 2 Adjustable LED 3.25 MOA
The Trijicon RMR Type 2 Adjustable LED 3.25 MOA is one of the most recognizable pistol red dot designs and is built around a compact, rugged housing. For an AXE owner looking for a traditional duty-oriented pistol optic, the RMR Type 2 provides a straightforward configuration without the additional reticle choices found on some competing models.
Its 3.25 MOA dot represents a middle ground between a very small precision-oriented dot and a large close-range aiming point. It can provide a defined aiming reference without taking up as much of the target as a larger reticle. The adjustable LED version also allows the brightness to be manually configured according to the lighting conditions.
The RMR’s compact form is particularly useful on a pistol slide because it does not require a large amount of space. Its distinctive housing is designed to protect the lens and electronics from impacts. This construction is one reason the RMR platform has become common among pistol optics users.
Another consideration is the RMR footprint. The footprint is widely supported by pistol slides and adapter plates, but the buyer should still verify the exact plate supplied with the BUL Armory AXE. Mounting hardware should also be selected according to the manufacturer’s specifications rather than assuming that every RMR-compatible screw set is interchangeable.
The RMR Type 2 is therefore a suitable option for AXE owners who want a compact optic with a simple aiming point and a rugged design. It does not offer the multi-reticle flexibility of the HS507C X2, but its straightforward operating concept can appeal to users who prefer simplicity.
Features
- 3.25 MOA red dot
- Adjustable LED illumination
- Compact pistol design
- RMR footprint
- Rugged housing
- Manual brightness adjustment
Pros
- Rugged and compact design
- Simple aiming point
- Established RMR footprint
- Good choice for demanding use
- Straightforward controls
Cons
- Higher cost than many budget alternatives
3. Holosun HE508T-GR X2 2 MOA Dot & 32 MOA Circle
The Holosun HE508T-GR X2 2 MOA Dot & 32 MOA Circle is a premium open reflex sight that combines a multi-reticle system with a titanium housing. Holosun specifies a Grade 5 titanium construction, which distinguishes the HE508T X2 from aluminum-bodied models such as the HS507C X2.
The green reticle is one of the primary differences between this model and conventional red-reticle optics. Green illumination can appear more visible to some shooters depending on their eyesight, lighting conditions, and individual preference. The sight provides a 2 MOA dot, 32 MOA circle, or circle-dot combination through its Multi-Reticle System.
Like several Holosun pistol optics, the HE508T-GR X2 incorporates Solar Failsafe and Shake Awake technology. The optic also includes a side-mounted CR1632 battery, allowing the battery to be replaced without taking the sight off the pistol. Holosun specifies up to 50,000 hours of battery life at setting 6.
The optic uses the RMR footprint and has a 0.63 × 0.91-inch window. It also features IP67 protection and is rated for substantial vibration resistance. The titanium housing contributes to its premium positioning while maintaining a relatively compact footprint for a pistol optic.
Features
- 2 MOA dot
- 32 MOA circle
- Green reticle
- Grade 5 titanium housing
- Solar Failsafe
- Shake Awake
- Side-loading CR1632 battery

4. Trijicon SRO 2.5 MOA
The Trijicon SRO 2.5 MOA is designed around a large viewing window intended to make it easier to find the aiming point quickly. For an optics-ready BUL Armory AXE, the SRO can be particularly interesting for shooters who place a high value on an unobstructed sight picture.
Its 2.5 MOA dot provides a relatively precise aiming point while remaining sufficiently visible for rapid target acquisition. Compared with smaller-window pistol optics, the SRO’s large window provides more visual space around the dot, which can make the optic feel more forgiving when the pistol is presented to the target.
The SRO also features adjustable illumination, allowing the reticle brightness to be matched to different lighting conditions. This is useful when moving between indoor and outdoor environments, although users should always verify the dot remains visible and appropriately adjusted before shooting.
Another important consideration is mounting compatibility. The SRO is based around the RMR mounting pattern, making it compatible with appropriate RMR-pattern mounting solutions. However, the large housing and window design should be checked against the specific AXE model and plate arrangement before purchase.
The SRO is consequently an appealing choice for AXE owners who prioritize viewing area and rapid visual acquisition. Its large-window design comes with a larger physical profile than some compact pistol optics, so users should consider holster compatibility and the intended role of the pistol.
Features
- 2.5 MOA red dot
- Large viewing window
- Adjustable illumination

One of the notable features of the DeltaPoint Pro is its Motion Sensor Technology. According to Leupold, the illumination switches off after five minutes of inactivity and turns back on when motion is detected. The optic also has multiple illumination settings, allowing the user to adjust brightness according to the environment.
Battery replacement is designed to be straightforward. The DeltaPoint Pro uses a spring-loaded, top-access battery compartment, meaning the optic does not have to be removed from the firearm to replace the battery. This can simplify maintenance and avoid the need to re-zero after routine battery replacement.
The optic weighs approximately 2 ounces and uses 1 MOA adjustment increments. Leupold also states that the DeltaPoint Pro is waterproof and designed to withstand substantial recoil.

Cons
- Requires compatible mounting plate
6. Holosun HS407C X2 2 MOA Red Dot
The Holosun HS407C X2 2 MOA Red Dot is a straightforward alternative to the more feature-rich HS507C X2. Instead of a selectable circle-and-dot reticle, the HS407C X2 uses a simple 2 MOA dot. This makes it suitable for shooters who prefer a clean aiming point without additional reticle elements. Holosun lists it as an RMR-footprint optic.
The 2 MOA dot is designed to provide a precise aiming reference while keeping the sight picture uncluttered.

Factors to Consider When Choosing the 6 Best Red Dot Sight for Bul Armory AXE
Footprint Compatibility
Footprint compatibility should be checked before anything else. An optic that does not match the mounting plate on your particular AXE will not simply become compatible because it is a popular pistol sight. The HS507C X2 and HS407C X2, for example, use the RMR footprint, while the DeltaPoint Pro uses a different mounting system. Always verify the exact AXE model and available plate.
Window Size
Window size affects how much of the target environment you can see through the optic. Larger-window sights such as the SRO can provide a spacious sight picture, while compact optics generally have a smaller physical profile. Consider how much space you want on the AXE and whether your preferred holster accommodates the optic.
Reticle Size and Design
Reticle choice is largely a matter of personal preference and intended use. A 2 MOA dot provides a relatively precise aiming point, while a larger circle or circle-dot configuration can provide a more prominent visual reference. The HS507C X2 and HE508T-GR X2 offer multiple reticle choices, whereas the HS407C X2 uses a simple 2 MOA dot.
Durability
A pistol optic needs to tolerate repeated slide movement, recoil, handling, and environmental exposure. Housing material is one factor to consider. The HE508T-GR X2 uses titanium, while the HS507C X2 and HS407C X2 use 7075-T6 aluminum housings. Weather-resistance ratings and construction should also be considered.
Size and Weight
A pistol-mounted optic should be appropriately sized for the AXE and your intended setup. A large optic can provide a larger viewing window, but it can also affect holster compatibility and the overall profile of the pistol. Compact optics may be easier to integrate into a concealed or compact configuration.
