If you are shopping for a pistol reflex sight with an RMR-style footprint, the Red Lost Soul II stands out for a simple reason: it combines a 6 MOA green dot, a wide viewing window, and side battery access in one compact optic.
This Red Lost Soul II review focuses on what the listing supports and where the tradeoffs are.
Lost Soul II Review Summary
The Red Lost Soul II looks aimed at buyers who want a straightforward carry-or-range optic without a complicated setup.
The combination of a green dot, multiple brightness settings, a shake-awake mode, and a universal RMR/507C/407C/SRO footprint makes it easy to place in the category of practical pistol optics rather than specialized competition glass.
If your priority is compatibility, quick battery changes, and a no-nonsense sight picture, this model has the right feature mix.
The strongest case for it is that it concentrates the essentials.
A 24 x 20 mm window is not oversized, but it is large enough to give a usable field of view on a handgun.
The IPX7 waterproof rating, 1800G shock resistance, and 7075 aluminum housing suggest a durable build on paper.
The listing also claims up to 60,000 hours of battery life with automatic sleep mode, which is the kind of convenience feature buyers usually want on a carry optic.
Review Scorecard
| Category | Score | Buyer-focused rationale |
|---|---|---|
| Footprint compatibility | 9/10 | Fits common RMR 508T/507C/407C/SRO-style mounts, which broadens handgun fitment. |
| Ease of use | 8/10 | Side battery access and shake awake reduce routine hassle. |
| Sight picture | 8/10 | The 6 MOA green dot and wide window favor fast acquisition. |
| Durability | 8/10 | 7075 aluminum, IPX7 waterproofing, and 1800G shock resistance are strong listed protections. |
| Carry practicality | 8/10 | Compact reflex format and sleep mode make it sensible for everyday use. |
| Feature simplicity | 7/10 | Useful controls without much complexity, though buyers wanting more reticle variety may look elsewhere. |
| Value proposition | 7/10 | The feature set is well chosen, but the listing alone does not prove premium-tier refinement. |
Bottom line: the Red Lost Soul II makes the most sense for buyers who want a practical, compatible reflex optic with low-maintenance features. It is less compelling for anyone who wants a very large window, a broader reticle menu, or a product with deeper published specs.
Key Features and Specifications of Lost Soul II
The core identity of this optic is clear: it is a compact reflex sight built around an RMR-compatible footprint.
The listing says it works with handguns using RMR 508T, 507C, 407C, and SRO footprints, so the main appeal is broad compatibility rather than a niche mounting system.
Here are the most useful listed details:
| Spec | What the listing says |
|---|---|
| Dot type | 6 MOA green dot |
| Window size | 24 x 20 mm, or 0.95 x 0.79 in |
| Battery access | Side battery design |
| Motion feature | Shake awake |
| Sleep mode | Automatic sleep after four minutes of inactivity |
| Battery life claim | Up to 60,000 hours |
| Waterproof rating | IPX7 |
| Shock resistance | Up to 1800G |
| Housing material | 7075 aerospace-grade aluminum |
| Finish | Matte anodized surface |
The 6 MOA dot is worth paying attention to because it tells you what kind of shooting this optic is trying to support.
A larger dot usually favors fast pickup and simple aiming over tiny precision work.
That lines up with the handgun use case and the product’s reflex-style format.
The side battery design is another practical detail.
On an optic intended for pistols, battery changes can become annoying if they require removing the sight.
Side access is a clear convenience feature because it keeps maintenance simpler.
The listing also emphasizes durability in a way that matters for a handgun optic.
IPX7 waterproofing, 1800G shock resistance, and 7075 aluminum all point to a build intended for regular carry or training rather than decorative range use only.
Still, those are manufacturer claims, not independent test results, so they should be read as stated capabilities rather than proven field benchmarks.
Pros and Cons of Lost Soul II
Pros
- Broad footprint compatibility with common RMR-style handgun setups.
- Green 6 MOA dot that should support fast target acquisition.
- Side battery access makes upkeep easier than bottom-access designs.
- Shake awake and sleep mode help conserve battery without much user effort.
- 7075 aluminum housing and listed shock/water resistance add confidence on paper.
- Compact window size keeps the optic practical for handgun use.
Cons
- The listing does not provide much detail on reticle options beyond the 6 MOA dot.
- The window is useful, but not especially large compared with some premium enclosed or oversized options.
- Because the evidence is limited to listing data, there is no independent confirmation of optical clarity, emitter performance, or long-term durability.
- Buyers who want a more competition-oriented optic may want a broader feature set.
Overall, the pros lean toward practicality and compatibility, while the cons mostly come from limited published detail.
That is a workable tradeoff for many handgun buyers, but it is still a tradeoff.
Who Should Buy Lost Soul II?
The Red Lost Soul II makes the most sense for buyers building or upgrading a pistol around a common RMR-style cut.
If you want a green-dot optic with basic low-friction conveniences, this is a reasonable fit.
The side battery door and shake-awake behavior are especially relevant if you plan to keep the optic on a defensive handgun or a gun that gets frequent range use.
It also suits buyers who prefer an uncomplicated sight picture.
A 6 MOA dot is easier to explain and use than a multi-reticle system, especially for someone who wants to learn the optic quickly and focus on consistent presentation.
You should probably skip it if you want a premium optics shopping experience with detailed independent lab specs, multiple reticle patterns, or an especially large viewing window.
It may also be a weaker fit for shooters who already know they prefer red dots over green dots, since this model is specifically a green-dot optic.
In short, buy it for convenience, compatibility, and a simple aiming solution.
Skip it if your decision process depends on niche competition features or a deeper published spec sheet.
Mounting and Everyday Use for Lost Soul II
RMR-Footprint Fit
The most important practical point is fit.
Because the listing calls out RMR, 508T, 507C, 407C, and SRO footprints, the optic is positioned for common handgun slides and plates rather than an obscure mounting standard.
That lowers friction for buyers who already own a compatible pistol or plan to build around one.
Battery Maintenance
Side battery access matters more than it sounds.
On a pistol optic, anything that reduces the need to remove the sight is helpful because it keeps zero maintenance simpler and reduces downtime.
Combined with shake awake and a four-minute sleep mode, the optic is clearly designed to be easier to live with than a basic always-on sight.
Dot Size and Window
The 6 MOA dot should appeal to people who value speed over tiny precision aiming.
Paired with a 24 x 20 mm window, it suggests quick visual pickup in defensive or general range use.
That is a sensible pairing for a compact reflex optic, even if it will not satisfy every shooter who prefers finer aiming references.
Durability Claims
The durability story is one of the more appealing parts of the listing.
7075 aluminum, IPX7 waterproofing, and 1800G shock resistance together create a profile that sounds ready for hard use.
The careful buyer should still remember that these are listing claims, but they are the right kind of claims for this product category.
Alternatives to Lost Soul II
If you are comparing options, the most sensible alternatives are other well-known pistol optics with proven market presence and similar footprints.
Look at:
These are credible comparison points because they sit in the same broad handgun-optic conversation, especially for buyers thinking about RMR-style mounts and everyday carry use.
The Holosun options are the closest fit if you want to stay in the same compatibility lane, while the Trijicon name will matter to buyers who prioritize a long-established premium benchmark.
The Vortex option is worth checking if you want to compare a newer carry-oriented optic against the Lost Soul II’s feature set.
Is Lost Soul II Worth It?
The Red Lost Soul II is worth considering if you want a practical, RMR-footprint pistol reflex sight with a green 6 MOA dot, side battery access, and shake-awake convenience.
The listing supports a clear buyer case: it is built for easy compatibility, simple operation, and everyday use.
If you want the safest buy based only on widely known brand reputation and deeper published detail, you may still prefer one of the better-known alternatives.
But if your priority is a straightforward optic with the right mounting language and the right convenience features, the Red Lost Soul II looks like a sensible shortlist candidate.
