The Harris Engineering #S-BRM Benchrest 6–9" Notched Swivel Bipod is a mechanical rifle support designed for low-profile stability during precision shooting. It attaches directly to standard quick-detach (QD) rifle sling swivel studs and features a built-in rear loop for sling attachment. Constructed from heat-treated steel and high-strength black anodized aluminum alloy, it utilizes a swivel base that allows shooters to tilt the firearm side-to-side to level the crosshairs on uneven ground. Spring-loaded legs deploy instantly with the push of a release button and lock securely into 1-inch notched increments to prevent slippage under recoil.

Key Features

• Swivel Base Mechanism: Allows side-to-side canting and tilting to achieve a level shooting platform on uneven surfaces, with adjustable friction controlled via an underside tension knob.
• Spring-Loaded Notched Legs: Automatically eject and lock into rigid 1-inch intervals to maintain height settings under heavy recoil.
• Direct Stud Mounting: Clamps securely onto standard rifle sling swivel studs without modifying the rifle stock.
• Durable Construction: Built from heat-treated steel and hard-anodized aluminum alloy, fitted with hard rubber leg caps and a polymer tension adjustment knob.
• Integrated Sling Attachment: Incorporates a rear sling loop to allow standard rifle sling usage while the bipod is mounted.

Who is the Harris S-BRM 6-9" Swivel Bipod for?

• Benchrest precision shooters — provides a stable, low-profile rifle platform with an adjustable height range of 6 inches to 9 inches that aligns cleanly with standard bench rests while keeping overall added weight down to 13 to 14 oz.
• Prone target shooters and varmint hunters — utilizes a swivel base mechanism combined with a compact 13 to 14 oz carry weight and 6 to 9 inch elevation to level crosshairs instantly on uneven natural terrain without altering leg lengths.

Less suitable for: Shooting positions requiring clearance over medium-to-tall grass, sage, wheat crops, steep uphill angles, or sitting and kneeling stances where the 6–9" height limit is too low; these scenarios require a taller bipod type such as a 9–13" or 12–25" extended shooting bipod. It is also not directly compatible with Picatinny 1913 or M-LOK handguards without separate aftermarket adaptors.
