Will the Harris #3 Adapter fit my Remington Model 750 or 742 semi-automatic rifle?

No, the Harris HADAP3 adapter is strictly engineered for the Remington Model 4, 74, and 7400 rifles. It features a specific fore-end screw profile that is not compatible with the Remington 740, 742, 750, or bolt-action models, which require different adapter types.

Do I need to drill or permanently modify my factory Remington stock to install this adapter?

No permanent drilling or wood alteration is required for installation. The adapter utilizes a two-part system containing a replacement fore-end screw and a contoured mounting base that anchors firmly to the fore-end cap, providing a stable mounting point without harming your factory stock.

What bipods and slings pair best with the Harris #3 adapter for outback hunting?

The adapter creates a standard sling swivel stud mount that is fully compatible with all clamp-style Harris ultralight bipods, such as the Harris HS-BR or H-SBRM models. It also retains dual-purpose functionality by allowing you to attach standard sling swivel loops for comfortable multi-day carry across rugged Australian terrain.

How does the all-steel construction hold up against harsh Australian bush conditions?

Constructed from heat-treated steel and hard alloys with a durable black finish, the Harris #3 adapter is built to withstand extreme outback weather conditions. The robust metallic construction provides reliable resistance against wear and corrosion during extended hunting or pest control trips in both hot and cold climates.

Remington Bipod Adapter - Harris HADAP3

The Harris No. 3 Bipod Adapter (HADAP3) is a precision-machined mechanical mounting interface designed to attach clamp-style Harris ultralight bipods to select Remington semi-automatic centerfire rifles. Manufactured in the USA from heat-treated steel and hard alloys with a durable black finish, this hardware replaces the factory fore-end screw on compatible rifles without requiring permanent alterations or drilling into wooden stocks. Once installed, it provides a standard sling swivel stud on the fore-end cap, giving shooters a solid mounting platform for both bipods and standard carrying slings.

Key Features

No-Drill Installation: Replaces the factory fore-end screw to install a stable bipod stud without drilling, tapping, or modifying factory woodwork.
Two-Piece Mechanical System: Combines a replacement fore-end screw and a contoured base plate to anchor securely to the factory fore-end cap.
Heat-Treated Construction: Built from heat-treated steel and hard alloy components with a matte black finish to withstand field conditions and centerfire recoil.
Dual-Purpose Stud: Serves as a direct clamping interface for standard Harris bipods while maintaining compatibility with conventional sling swivels.
