Comparing the EOTech EFLX and Trijicon SRO on dot size, footprint, and use case so you can pick the right pistol red dot.
Quick Answer
The EOTech EFLX is the better value if you want a 3 MOA dot and a Leupold Delta Point Pro footprint that fits many milled slides or dovetail adapters. The Trijicon SRO is the stronger pick for competition or fast shooting, thanks to its 5 MOA dot, wide field of view, and both manual and automatic LED brightness modes. Neither is universally better—match the dot size and mounting system to your pistol and your shooting style.
Dot Size: 3 MOA vs 5 MOA
The EFLX uses a 3 MOA dot, while the SRO uses a 5 MOA dot. A 3 MOA dot covers less of the target at distance, which helps with precise shot placement on small targets or when shooting at longer ranges. A 5 MOA dot is easier to pick up quickly, especially under recoil or in bright light, but it covers more of the target at distance. If you shoot mostly close-range or action-oriented drills, the larger dot can be faster. If you prioritize precision, the smaller dot has an edge.
Footprint and Mounting
The EFLX base is configured to the Leupold Delta Point Pro footprint, so it will adapt to appropriately milled slides or a rear dovetail mounting adapter. The SRO uses the Trijicon RMR footprint, which is one of the most common mounting standards for milled slides and adapter plates. Before buying either, confirm your slide is milled for the matching footprint or that you have the correct adapter plate. If your pistol is already milled for RMR, the SRO mounts directly; if it is milled for Delta Point Pro, the EFLX is the direct fit.
Brightness and Controls
The SRO offers both manual and automatic LED brightness modes, letting you lock in a setting or let the sight adjust to changing light. The EFLX catalog information does not specify its brightness modes, so if automatic adjustment is a must-have for you, verify that detail before buying. For carry or duty use where lighting changes often, the SRO's dual-mode system is a practical advantage.
Use Case and Durability
The EFLX is described as ideal for professional use, hunting, home defense, and as a 1X solution on a variety of platforms. The SRO is built for speed, making it a natural fit for competitive shooting or any scenario where rapid target acquisition and quick dot recovery matter. Both are capable optics, but they are optimized for different priorities: the EFLX leans toward versatility and value, while the SRO leans toward speed and competition performance.
Trade-Offs at a Glance
- Dot size: EFLX: 3 MOA for precision at distance. SRO: 5 MOA for faster acquisition up close. Choose 3 MOA if you value precision; choose 5 MOA if you value speed.
- Footprint: EFLX uses the Leupold Delta Point Pro footprint; SRO uses the Trijicon RMR footprint. Match the footprint to your slide or adapter plate before you buy.
- Brightness control: SRO has manual and automatic LED modes; EFLX brightness modes are not specified in the catalog. If auto-brightness matters, confirm the EFLX specs or lean toward the SRO.
- Primary use: EFLX is pitched for professional use, hunting, home defense, and as a 1X option on multiple platforms. SRO is built for speed and competition-style shooting. Pick the EFLX for broad versatility; pick the SRO for fast, competition-focused shooting.
Product Facts
- Eotech EFLX / Tan - 3 MOA: The EFLX Mini Reflex Sight is EOTECH's first venture into reflex technology optics. It is designed for pistol use with a Leupold Delta Point Pro footprint and can adapt to appropriately milled slides or a rear dovetail mounting adapter. It is also ideal as a 1X solution on a variety of platforms. The Delta Point Pro footprint gives you flexibility if your slide is already cut for that pattern or you use a dovetail adapter, and the 1X versatility means it can work on more than just a pistol.
- Trijicon SRO - 5 MOA: The Trijicon SRO 5.0 MOA Adjustable LED red dot is built for speed, with a wide field of view and a crisp, clean dot. It features both manual and automatic LED brightness modes. The 5 MOA dot and wide view make it easier to find the dot quickly, and the dual brightness modes let you adapt to changing light without losing your setting.
Which Should You Choose?
Best for
- Shooters who want a 3 MOA dot for more precise shot placement
- Pistols already milled for the Leupold Delta Point Pro footprint or using a dovetail adapter
- Home defense, hunting, or multi-platform use where a 1X reflex sight fits
Not for
- Competitors who prioritize the fastest dot acquisition and a wide field of view
- Shooters who need confirmed automatic brightness adjustment (verify EFLX specs first)
- Pistols milled only for the RMR footprint without an adapter plate
