MOA
MOA
MOA stands for Minute of Angle and indicates the rail's incline. An angled rail compensates for bullet drop over distance by tilting the scope slightly forward. This gives you more elevation adjustment in the scope's turret – if you need to shoot really long distances.
For most target and hunting scenarios, 0 MOA (flat rail) is more than sufficient. If you are shooting at longer distances or using a scope with limited elevation, 10 or 20 MOA can give you the extra margin you need.

Material
Material
This rail is made of steel, which remains the classic choice for both mounts and Picatinny rails. Steel has high rigidity and is extremely durable. The material withstands repeated mounting and dismounting without deforming the contact surfaces.
Steel is heavier than aluminum, but for a Picatinny rail, the weight difference is practically minimal – typically less than 50 grams.

Surface treatment
Surface treatment
This rail has undergone QPQ treatment (Quench-Polish-Quench). QPQ is a salt bath nitriding process that creates an extremely hard and corrosion-resistant surface. The treatment penetrates the steel and is not merely a coating – even deep scratches will still reveal treated material.
QPQ provides a matte, black finish and is the most durable surface treatment for steel rails and steel mounts. A QPQ-treated rail requires minimal maintenance and can withstand harsh use in all weather conditions.

Mounting
Mounting
Mounting this rail is quick and easy. The rail is attached directly to the rifle's receiver with the included screws.
Manufacturer's recommendation:
- Torque: 3.5 Nm
- Use oil on the screws (NOT threadlocker)
- Tighten the screws criss-cross for even distribution
A torque wrench is necessary for proper mounting. Overtightening can damage the threads in the receiver.

Compatibility
Compatibility
This rail is manufactured according to the NATO STANAG 2324 / MIL-STD-1913 standard (Picatinny). This means it is compatible with all standard Picatinny mounts, rings, and accessories – regardless of the manufacturer.
The Picatinny standard ensures that you can freely combine rails, mounts, and optics from different manufacturers. This gives you the flexibility to upgrade or change your scope without changing the rail.
