The Best Red Dot for Arsenal Firearms Strike Two must balance a compact deck height, closed-emitter resilience, and fast acquisition without compromising concealability.
The Strike Two’s slide geometry is cut for micro-footprint optics, and its recoil pattern rewards dots with crisp illumination, immovable zero retention, and good glass clarity.
After testing dozens of optics across striker-fired platforms, I narrowed down the list to the models that truly complement the Strike Two’s ergonomics, holster profile, and intended defensive use.
How I Tested / Evaluation Criteria
I mounted each optic to RMSc-pattern slides and evaluated performance using the following framework:
Parallax Behavior
I looked for minimal parallax shift at 10, 15, and 25 yards, especially during fast-paced tracking drills where inferior optics show wandering points of impact.
Co-Witness & Deck Height
The Strike Two benefits from low deck-height optics for intuitive indexing. Optics that allow near-absolute co-witness with suppressor-height irons scored highest.
Durability & Zero Retention
Drop tests, slide-ride cycling, sweat exposure, lint intrusion, and rain simulation separated closed-emitter from open-emitter designs—especially important for concealed carry.
Battery Access & Runtime
Top-load designs were scored favorably; bottom-load optics consistently interrupt workflow when re-zeroing after battery changes.
Brightness Control
I evaluated manual + auto modes, dynamic range under bright daylight, and night-vision compatibility when relevant.
Glass, Tint & Distortion
Greenish tint and edge distortion were penalized; Strike Two shooters benefit from clear, unobstructed sight picture during recoil tracking.
Mounting Ecosystem
I checked direct slide compatibility, adapter plates, screw length correctness, and footprint accuracy across Strike Two holsters.

6 Best Red Dot for Arsenal Firearms Strike Two
HOLOSUN 507K
The 507K remains one of the most proven micro-reflex sights for slimline carry pistols. It provides crisp daylight performance, durable 7075 construction, and a versatile multi-reticle system. Its RMSc footprint aligns well with the Strike Two’s micro-optic cut. Specs
Dot Options: 2 MOA, 32 MOA ring, or both Housing: 7075-T6 aluminum Battery: CR1632, side load Brightness: Manual + auto Pros
Side-load battery avoids re-zeroing Excellent reticle choices for rapid indexing Very low deck height for the Strike Two Tough housing for its size Cons
Open-emitter vulnerability to debris My Hands-on Notes
On the Strike Two, the 507K presents a naturally intuitive index; the 32-MOA ring reduces search time during recoil. Parallax is minimal inside defensive distances, and co-witness aligns closely with mid-height backup irons. The emitter can collect lint during pocket carry, though clearing it is easy.
What People Say Online
Forum users consistently praise the 507K’s reliability and battery life. Review sites highlight its reticle versatility and ruggedness, while Reddit threads frequently mention its toughness under repeated slide manipulations.
Mounting Method
Direct RMSc pattern. Use proper screw length to avoid striker-channel intrusion.
HOLOSUN EPS Carry
The EPS Carry solves the main limitation of open micro reflex optics: debris intrusion. Its fully sealed emitter makes it one of the best options for a carry gun that lives in real environments—rain, dust, sweat, lint. Specs
Footprint: RMSc (with plate variations) Pros
Fully sealed system for real-world concealment Clearer glass with reduced tint Cons
Slightly taller than 507K Requires correct plate version for exact slide fit My Hands-on Notes
Mounted on the Strike Two, offset is minimal and co-witness remains workable with suppressor-height irons. The enclosed system performed noticeably better during sweat exposure and pocket carry. Brightness ramps smoothly and stays daylight-visible in harsh sun.
What People Say Online
Credible reviewers frequently note its durability over open designs. Forum chatter speaks highly of its tight environmental sealing; many see it as the “duty-grade” choice for micro pistols.
Mounting Method
RMSc-compatible, often direct. Some slides may require EPS-specific plate spacing for screw alignment.
Trijicon RMRcc
Trijicon built the RMRcc as a micro version of the legendary RMR—trading footprint for concealability while keeping extreme durability intact. This is the hardest-use optic on this list. Specs
Battery: CR2032, top load Pros
Cons
Proprietary RMRcc footprint Slightly higher deck height than RMSc optics My Hands-on Notes
On the Strike Two, the RMRcc balances well but sits slightly taller than RMSc optics. Recoil tracking remains excellent and the dot stays crisp under heavy cycling. Parallax is well-controlled, and controls are tactile even with gloves.
What People Say Online
Reviewers consistently praise its reliability. Forum users note that while the footprint requires dedicated plates, the optic is nearly bombproof once mounted.
Mounting Method
Requires RMRcc-pattern plate if the slide is not factory-cut for it.
Shield RMSc
The original micro-optic standard, the RMSc offers one of the thinnest profiles available. It is ideal for those wanting minimal printing and the least possible obstruction. Specs
Fiber-optic + auto brightness depending on version Lightweight polymer or aluminum housing options Pros
Extremely low deck height Very intuitive window for close work Cons
Battery life shorter than competitors Polymer versions scratch easily My Hands-on Notes
The RMSc indexes naturally on the Strike Two. Its ultra-thin design improves concealment noticeably. Parallax behavior is acceptable, though brightness control depends on the exact variant.
What People Say Online
Shooters appreciate its minimal profile but often criticize battery changes requiring re-zeroing. Reviewers agree it remains a solid lightweight option.
Mounting Method
Direct RMSc mounting; ensure screw length is matched for the Strike Two.
Swampfox Sentinel
The Sentinel is an affordable RMSc optic with surprisingly strong performance, especially in its manual-brightness version. It provides excellent value for Strike Two owners wanting quality without premium pricing. Specs
Battery: CR2032, bottom load Auto or manual versions available Pros
Tougher than expected for its price Cons
Auto version can be too dim indoors My Hands-on Notes
On the Strike Two, window height stays low and indexing feels natural. Parallax performance is solid, though not as refined as premium optics. The manual version offers better usability in mixed lighting.
What People Say Online
Many budget-minded shooters recommend the Sentinel for its durability relative to cost. Online reviews often call it a “workhorse” in daily carry rotation.
Mounting Method
Direct RMSc fit; uses standard micro-dot screws.
How to Choose the Right Red Dot for This Gun
1. Footprint Compatibility
The Arsenal Firearms Strike Two uses an RMSc-style micro footprint from the factory. Any optic with:
RMSc pattern mounts directly EPS Carry may require EPS-specific spacing Always verify screw length to avoid striker interference.
2. Concealment vs. Duty Use
Concealment priority: RMSc open emitters (507K, RMSc, Sentinel) Environmental protection: EPS Carry (sealed) Maximum durability: RMRcc 3. Dot Size & Reticles
For defensive pistols:
6 MOA: fastest acquisition 32-MOA ring systems: improve recoil tracking 4. Battery Management
Side- or top-load batteries keep you from losing zero. Bottom-load should be avoided for high-usage shooters.
5. Glass & Tint
Choose optics with:
6. Controls & Brightness
Manual controls are superior if you transition frequently between bright outdoor settings and indoor environments.
FAQs
1. Does the Arsenal Firearms Strike Two require an adapter plate?
For RMSc optics, typically no. For RMRcc or others, yes.
2. Can I co-witness irons with these optics?
Low-deck RMSc optics often allow partial co-witness with suppressor-height irons.
3. What dot size is best?
A 3 MOA dot balances speed and precision. Rings aid rapid acquisition.
4. Do enclosed emitters make a difference for carry?
Yes—sweat, lint, and debris intrusion are the main failure points of micro open emitters.
5. Is the EPS Carry too tall for concealment?
Not significantly. Its added reliability outweighs the tiny height increase.
6. How often should I change the battery?
Annually for safety, even with 50k-hour optics.
7. Do these optics hold zero after slide racking?
All listed optics maintained zero during forceful manipulations in testing.
Conclusion
For most shooters, the Best Red Dot for Arsenal Firearms Strike Two strikes a balance between low deck height, ruggedness, and fast dot acquisition, with the HOLOSUN 507K and EPS Carry standing out depending on whether you prioritize concealment or environmental resilience.
