Picatinny Ring Mount | 35 mm | Screw

This assembly is anodized. Anodizing creates a protective oxide layer on the aluminum surface, which provides good corrosion protection and a durable finish. Anodized products can withstand daily use and are resistant to scratches and wear.

Hard anodizing (Type III) provides a thicker and harder layer than standard anodizing and is typically used on products exposed to extra heavy wear.

Installation is simple. Attach the rings to the picatinny rail, place the scope in the lower ring halves, then tighten the upper halves.

Manufacturer's recommendation:
• Torque for ring screws (top, M3.5): 1.8–2.0 Nm
• Torque for mounting to rail (M4): 2.0–2.5 Nm
• Ensure the scope is level and has correct eye relief before final tightening

A torque wrench is necessary for correct installation. Overtightening can damage the scope's tube.

This mount is made from 7075-T6 aluminum – the same alloy used in military equipment, aircraft structures, and high-end climbing gear. 7075-T6 has a strength-to-weight ratio almost twice that of steel and is the preferred material for many professional shooters.

For the vast majority of hunters and shooters, 7075-T6 aluminum is at least as good as steel. The material is lighter, does not corrode, and will last for decades of use under normal conditions.

The mounting height of rings is typically specified as BH (Base Height) — measured from the top of the Picatinny rail to the bottom of the scope tube (the saddle).

When calculating the total height (Center Height), you should add the radius of the scope tube to the BH measurement. For a 30 mm tube, the radius is 15 mm. For a 34 mm tube, the radius is 17 mm.

Formula: Center Height = BH + r

Remember that the Picatinny rail itself raises the mounting point (typically 5-10 mm depending on the rifle model). This means you can often choose a lower ring than you would otherwise need.

Rule of thumb: Choose the lowest ring height that still allows free passage between the scope's objective and the barrel. A lower mount provides better balance and a more natural sight picture.

These rings have an internal diameter of 35 mm and are suitable for scopes with a 35 mm tube.

Always check your scope's tube diameter before purchasing – it can be found in the scope's specifications or easily checked with a caliper.
