The Harris Engineering S-25 (HS-25) Swivel Bipod is an elevated, mechanical rifle support engineered for field shooting across tall ground cover and undulating terrain. Catalogued as the Harris #S-25 High Rise 12–25" Swivel Bipod, it clamps directly to standard quick-detach (QD) sling swivel studs—such as those found on Tikka T3x, Howa 1500, Lithgow LA101/LA102, Sako, and Remington 700 rifles—and retains an integrated sling attachment point. Constructed in the USA from heat-treated steel and hard aluminium alloys with a black anodized finish, it utilizes a Series S hinged base that tilts side-to-side for rapid rifle levelling on uneven ground.

Key Features

• High-Rise Ground Clearance: Extends from 12 inches to 25 inches (approx. 30.5 cm to 63.5 cm), lifting the rifle bore above wheat stubble, tall prairie grass, crops, and snow.
• Three-Piece Telescoping Legs: Built with 3-piece smooth friction-lock legs that enable micro-adjustments to any custom height throughout the 12–25" range without fixed notch stops.
• Series S Swivel Base: Tilts side-to-side on a central pivot to level the rifle on cross-slopes and uneven natural surfaces.
• Field-Ready Construction: Features hard rubber foot caps, a polymer tension adjustment knob, and all-metal mechanical hardware for all-weather outdoor use.

Who is the Harris #S-25 High Rise 12-25" Swivel Bipod for?

• Australian Varmint and Pest Control Hunters — Requires a swivel hunting bipod that elevates from 12 inches to 25 inches to provide a stable, level rest for seated and kneeling shots over tall crop stubble, scrub, and undulating ground.
• Stalking Hunters Operating in Tall Grass, Crops, or Undulating Terrain — Needs 3-piece telescoping smooth friction-lock legs weighing 21 oz that allow continuous height micro-adjustments anywhere between 12 and 25 inches to accommodate steep vertical angles and variable seated positions.

Less suitable for: Flat prone shooting or benchrest competition where the 12-inch minimum height sits too tall (a lower-profile 6–9 inch or 9–13 inch bipod is required), or standing shots exceeding the 25-inch maximum extension (a dedicated shooting tripod or tall quad-sticks are required).
