DESCRIPTION

The Tier One ARCA to Picatinny Adaptor – Short is a precision-engineered solution for shooters running rifles with integrated ARCA rails who want fast, repeatable bipod mounting without compromise.

Machined from premium aluminium alloy and produced on advanced 5-axis CNC machines, this adaptor is held to exceptionally tight 3-micron tolerances, ensuring rock-solid stability and consistent accuracy. Manufactured under the same rigorous standards as Tier One’s renowned scope mounts and bipods, it delivers uncompromising performance in demanding environments.

The short configuration is ideally suited to rimfire rifles and slim rifle stocks, keeping weight to a minimum while maintaining strength and rigidity. It’s an excellent choice for precision rifle competitions, where rapid bipod repositioning and reliable lock-up are critical.

A clearly visible torque knob allows for quick, fine adjustments, even in high-pressure or low-visibility conditions. The adaptor also includes a high-tolerance CNC-machined Tier One™ Picatinny rail section, ensuring perfect interface alignment.
