ERATAC Picatinny Rail for AK47/74 – Short Red Dot Rail instead of Original AK Rear Sight
You want to mount a compact red dot sight centrally on an AK47/AK74 without having to set up a large side mount.
The ERATAC Picatinny Rail 57050-003J replaces the original rear sight leaf and creates a short Picatinny mounting surface above the barrel axis.
It is designed for non-magnifying red dot sights, not for long scopes or heavy optic setups. The rail is short, light, and flat – this is precisely its benefit, but also its limitation.
Important Note on Classification:
This rail changes the sight/optic logic of your AK: The original rear sight leaf is replaced. Before purchasing, check: AK47/AK74 model, rear sight mount, compatibility of your AK clone, desired optic, height of the red dot sight, zeroing after mounting, and whether you still need a mechanical sighting solution.
What makes this product technically special:
✔ Replaces the original rear sight leaf: creating a central optic mount without a side AK mount.
✔ 6 Picatinny slots: sufficient for many compact red dot sights, but not intended for long optic setups.
✔ 7075 aluminum: sensible for a lightweight rail that must still sit dimensionally stable on the weapon.
✔ Mil-Spec Type III hard anodizing: protects the surface and matches the ERATAC mounting logic.
✔ 37 g weight: keeps the AK setup significantly slimmer than many side mounts.
Why this product?
The AK platform is often more difficult than AR systems for optic mounting. Side rails, gas tube solutions, and dust cover mounts each have their own disadvantages in terms of height, repeatability, or ergonomics.
This ERATAC rail solves a small, clear problem: mounting a compact red dot flat and centrally. It is not a universal base for every optic, but a reduced solution for users who want to build a slim AK with a reflex sight.
-
Central optic position: the red dot sight sits above the barrel axis instead of offset to the side.
-
Short profile: the rail does not add unnecessary bulk and keeps the setup compact.
-
Red dot focus: particularly useful for fast target acquisition with non-magnifying optics.
-
Reversibility: since it is mounted in place of the rear sight, the conversion is fundamentally reversible, provided all original parts are retained.
Instructor's Tip: Don't just visually inspect after mounting
Tolerances are real with AK systems. Insert the rail cleanly, tighten it according to the manufacturer's specifications, and then check for play, canting, or a crooked optical line.
Always zero it afterwards. An optic on a newly mounted rail is never automatically zeroed.
Also, check if you still get a natural cheek weld with your chosen red dot height. Overly high setups negate the advantage of the compact AK solution.
Our Assessment
The ERATAC AK rail is strong if you are looking for a lightweight, central red dot solution for AK47/AK74. It is particularly interesting for sporting AK setups, training weapons, and compact field/range configurations where a large optic is not planned.
It is less suitable if you want to mount an LPVO, thermal attachment, large rifle scope, or heavy optics. For these, you need a different mounting base with more length, bearing surface, and sensible eye relief logic.
Suitable for:
- AK47/AK74 setups with a compact red dot sight
- Sport shooters looking for a flat, central optic mount
- Users who do not want to set up a large AK side mount
- Lightweight training and range configurations
Less suitable for:
- Long rifle scopes or LPVOs
- Heavy optics with a large lever on a short rail
- AK variants with incompatible rear sight mounts
- Users who want to retain the original mechanical rear sight unchanged
Direct Classification:
✔ ERATAC AK rail: light, flat, and direct for compact red dots above the barrel axis.
✔ AK side mount: better for larger optics, but often higher, heavier, and bulkier.
✔ Dust cover mount: can offer more surface area depending on the system, but heavily dependent on the quality of the dust cover and locking mechanism.
The ERATAC rail is worthwhile if you deliberately want to keep it small and central. It is not the right base for heavy or long optical systems.
Application Scenarios
-
Range / Training: compact red dot configuration for fast target acquisition.
-
Dynamic Sport Shooting: slim AK setup without a large side mount.
-
Hunting use with Red Dot: useful when short distances and fast target acquisition are the priority.
-
Conversion of existing AK setups: if the original rear sight is to make way for a Picatinny red dot mount.
Practical Tip: Secure Original Parts
Store the rear sight leaf, screws, and small parts neatly. Small original parts are easily lost, especially with AK conversions.
If you want to convert it back or sell the setup later, a complete original condition is much easier.
Features & Construction
-
Mounting position: in place of the original rear sight leaf – no classic side mount.
-
Picatinny profile: 6 slots for compact red dot sights and suitable Picatinny mounts.
-
Material: 7075 aluminum – high strength with low weight.
-
Nut block: hardened stainless steel – relevant for clamping in the weapon mount.
-
Height: 11 mm – keeps the optic base flat, but the final sight height is determined by your red dot mount.
-
Dimensions: 84 × 21 × 11 mm – short enough for compact AK setups, but limited for long optics.

FAQ
Does the rail fit every AK47 or AK74?
No. It is designed for AK47/AK74 setups, but AK clones and manufacturing tolerances may vary. Check the rear sight mount of your specific model before purchasing.
Can I mount a scope on it?
Technically it is a Picatinny rail, but practically it is intended for compact non-magnifying red dot sights. For LPVOs or long scopes, the rail is too short and not the most suitable base.
Do I have to re-zero after mounting?
Yes. After any change to optics or mounting, the point of impact must be checked and the optic re-zeroed.
Does the original rear sight remain?
No, the rail replaces the original rear sight leaf. You should keep the original part for a possible conversion back.
What is the advantage over a side mount?
The solution is lighter and more central. A side mount can be more sensible for larger optics, but usually builds heavier and higher.
Conclusion: The ERATAC Picatinny Rail for AK47/74 is a clean solution for users who want to mount a compact red dot flat on the AK. It is strong for slim training and range setups, but not the right base for large or heavy optics.
