The BT19 Atlas Accuracy International Spigot (AAIS) is designed for use with any NC (No Clamp) style Atlas Bipod that mounts directly to the AAIS which plugs into the Accuracy International AI/AICS stocks utilizing the factory retention/release mechanism.

The evolution of long range shooting and shooter’s demand drove subtle changes to the BT19. The latest modification stops the 3 to 9 rotation.

It is machined from 6061-T6 aluminum that is Mil-Spec Type III hard anodized mated with an alloy steel Spigot that is finished with a Manganese Phosphate. Includes two (2) 10-32 x 1″ flat head socket cap screws. Available in black only.

Weight: 4.7 ounces / 133 grams

IMPORTANT: When installing the BT19, please be sure to loosen the Tension Nut as much as possible before inserting the Spigot into the stock. Push the Spigot into the receptacle using the Tension Nut until there is a good, solid “click” of the spigot locking into place, then tighten the Tension Nut.

NOTE: The BT20 Atlas Accuracy International Spigot Rail Set is a three piece, 1913 rail set that can be attached to the BT19 AAIS. This accommodates for a multitude of mounting options including any of our rail mounted Atlas Bipods.
