Accuracy International Spigot Mount

(13 reviews) Write a Review


Anarchy Outdoor's Accuracy International Spigot Mount

This spigot mount is perfect for those struggling to get stable with an unsteady spigot bipod mount or want their Arca-Swiss compatible bipod mounted closer to the bore line. This one-piece bipod mount replaces the Accuracy International factory bipod “block” held within the square tube forend.

All versions of this bipod mount come machined from a single piece of 6061-T6 Aluminum and Type-III Hardcoated for enhanced durability. Its construction and design result in a rock-solid mount that eliminates spigot wiggle, providing the shooter with an optimized bipod attachment point. 

Installation is easy. It requires a 5/16” roll pin punch, 2.5mm Allen Key, 3mm Allen Key, and blue Loctite. If you are unsure how to install this mount, Anarchy Outdoors has a spigot mount installation video.  

Available Configurations

  •  Picatinny 
    • 5-slot Picatinny rail allows the mounting of bipods equipped with a standard Picatinny clamp mount.

  •  Arca-Swiss (RRS Dovetail)

    • It's compatible with bipods that have an Arca-Swiss mount.

    •  It includes two cap screws that can be used as a recoil stop to prevent the bipod from sliding forward. 

    • Its unique storage solution provides a place within the mount to keep the screws when unused.

    • It has M-Lok ™ standard mounting holes on the bottom face, which allows a 3 or 5-slot M-Lok Picatinny rail to mount underneath. The user can then use the Arca-Swiss bipod block as a regular Picatinny mount.

Compatible Rifles: Rifle Families


Accuracy International AE MKII, AE MKIII, AICS (Legacy), AW, AWM

AE MKI and certain Gen. 1 AW’s aren't compatible with this spigot mount. If these do not have the countersunk hole in the front of the chassis, seen with skins removed, this spigot mount will not work. These variants can be made compatible by machining the countersunk holes, which will require a competent gunsmith. Machining print provided.

  • The mount allows the user to use the factory HK hooks and Harris sling stud.


  • AE – Picatinny (4.7 oz)

  • AE – Arca-Swiss (4.8 oz) 

  • Accuracy International AT, ATAICS

    • The mount allows the user to install the factory AI Night Vision bridge and retains the use of the factory flush cups.


  • AT – Picatinny (6.0 oz)

  • AT – Arca-Swiss (6.2 oz)

NOTE: The weight for each variant is the total installed weight – don’t forget that about the factory bipod block removal! The factory AE/AW block weighs 2.6 oz, while the factory AT block weighs 4.0 oz. Combine that with the B&T BT19 and BT20 spigot bipod mount, which weighs 5.1 oz, and you have a total weight of 7.7 oz for the AE/AW and 9.1 oz for the AT. Removing both of those and installing this improved bipod mount nets a weight savings of 2.9 oz!!!

  • Super tight fit

    Posted by Mitchell on May 13th 2024

    The arca section is machined extremely well. Absolutely zero wobble in the "spigot channel". My bipod is moved forward and feels extremely sturdy. Almost as if Accuracy International included it on the AT when they first made it!
