Arcalock Rail Systems

Shop Arcalock rails at No Boring Guns for precision rifle mounting applications. Arcalock rail systems deliver repeatable zero and secure attachment for bipods, accessories, and support equipment on bolt-action and precision rifles.

Precision shooters demand mounting solutions that maintain zero across repeated attachment cycles while providing rock-solid support during recoil. Arcalock mounting rails address these requirements through dovetail interface design that eliminates the play and inconsistency found in alternative systems.

Arcalock rails use a dovetail profile standardized by Area 419, creating a mounting interface that combines tool-free attachment with exceptional rigidity. The system originated in photography equipment before precision rifle shooters recognized its advantages for firearm applications. Unlike traditional Picatinny or M-LOK systems, the dovetail design provides continuous contact along the entire rail length, distributing recoil forces more effectively.

Choosing Arcalock Mounting Rails

Mounting Configuration

Installation methods vary between direct-attach rails that bolt to chassis systems and universal rails requiring separate mounting hardware. Chassis-specific options integrate cleanly with factory mounting points on precision rifle chassis from manufacturers supporting the Arca interface standard. Universal rails adapt to stocks and forends lacking native Arca compatibility through separate clamp or bolt-through systems. Consider whether your rifle platform offers dedicated mounting points or requires adapter hardware before selecting rail length and attachment method.

Rail Length and Weight

Longer rails provide more adjustment range for bipod positioning and accessory placement but add weight to the forend. Competition shooters often prefer full-length systems maximizing flexibility in shooting positions. Hunting applications typically benefit from shorter, lighter rails minimizing carry weight while maintaining essential functionality. The tradeoff between adjustment versatility and weight savings depends on intended use – match rifles tolerate additional ounces that field rifles cannot.

Accessory Compatibility

Arca rails accept bipods, barrier stops, weights, and other accessories designed for the Arca interface. Verify that existing accessories use true Arca dovetail dimensions rather than similar but incompatible profiles. Some manufacturers produce proprietary variants that appear similar but lack full interchangeability. Quality rails feature clean machining with consistent dimensions ensuring smooth attachment and reliable clamping across accessories from different manufacturers.
