APW ARCA Clamp – ARCA/Picatinny Adapter for Bipods and Accessories
 
 The APW ARCA Clamp is a compact and robust adapter designed to fully utilize ARCA rails on a precision rifle, while maintaining compatibility with Atlas bipods and Picatinny rail-mounted accessories. It serves as a mechanical interface between the chassis's ARCA rail and the chosen accessory, allowing for continuous rail movement (very precise positioning) without compromising the Picatinny ecosystem already present in most shooters' rifles.
 
 The basic idea: a single clamp, mounted on an ARCA rail, capable of directly receiving an Atlas bipod via its original screws, and of accommodating, if needed, a small Picatinny rail supplied, which clips into the clamp to mount any 1913 accessory.
 

 
 Product role and philosophy
 
 ARCA rails have become essential in long-range shooting because they allow a bipod or tripod to slide along the entire length of the stock or chassis, with continuous adjustment rather than being limited to a few screw positions. The APW ARCA Clamp is designed to maximize this advantage:
 
 
 
 smooth translation of the bipod over the entire travel of the rail;
 
 
 precise adjustment of the rifle's center of gravity;
 
 
 rapid adaptation to height and type of support (barricade, bag, low wall, tripod, uneven terrain);
 
 
 possibility of alternating between Atlas bipod and Picatinny accessories without changing the basic configuration of the rifle.
 
 
 The clamp thus becomes the central piece that links the ARCA standard on the rifle side with the huge catalog of accessories designed for Picatinny or Atlas bipods.
 

 
 Compatibility and interfaces
 
 ARCA interface
 The APW ARCA Clamp attaches to a standard ARCA rail mounted under the handguard or chassis. The clamp's geometry provides a large contact surface on the rail, with a reliable clamping action designed to withstand the stresses of intensive use (prone shooting, angled supports, barricades, repeated handling).
 

 
 Atlas bipod compatibility
 The clamp is specifically designed to work with Atlas bipods using their original screws, without exotic parts or makeshift adaptations.
 Key points:
 
 
 
 compatible with Atlas QD and NC versions using standard screws;
 
 
 not compatible with older Atlas two-screw bipods;
 
 
 The interface is designed to retain the rigidity, controlled play and repeatability inherent to the bipod.
 
 
 In practice: if the Atlas bipod is already adjusted, tested and mastered by the shooter, the APW ARCA Clamp allows it to be "migrated" onto an ARCA rail without changing equipment.
