Atlas Bipod BT19 Accuracy International Spigot (AAIS)

The Atlas BT19 Accuracy International Spigot (AAIS), part number BT19 from B&T Industries, lets any NC (No Clamp) Atlas bipod mount directly to the Accuracy International spigot system — the factory forend interface on AI rifles. It keeps the AI forend as the manufacturer built it, with no rail bolted on.

How It Compares

The BT19 mounts NC bipods only. To run a two-screw or ADM lever Atlas bipod on the AI spigot, add the BT20 AAIS 1913 rail set, or take the ready-made quick-detach route with the Atlas BT43 leveraged rail, which is the BT20-B bottom rail supplied with an ADM-170-S lever installed. For M-LOK handguards instead of an AI spigot, use the Atlas BT70 M-LOK adaptor. NC bipods are in our Atlas bipod range.

Ideal For

• Accuracy International rifles with the factory spigot forend
• Long-range and PRS-style shooting on an AI platform
• Target, F-Class and practical rifle with an AI-stocked rifle

Frequently Asked Questions

Which Atlas bipods fit the BT19 spigot?
The BT19 fits every NC (No Clamp) Atlas bipod, which is the BT10-NC, BT46-NC, BT47-NC, BT35-NC, BT65-NC, BT69-NC and BT72-NC.

Will a two-screw or ADM lever Atlas bipod fit the BT19?
Not directly — those bipods carry a Picatinny clamp, so you need the BT20 AAIS rail set to add 1913 rails to the spigot, after which two-screw and lever-mount bipods can be used.

Which rifles does the BT19 suit?
The BT19 is for Accuracy International rifles that use the spigot forend interface, so check your specific model's forend before ordering.

Is there a quick-detach version already built?
Yes — the BT43 leveraged rail is the BT20-B bottom rail supplied with an ADM-170-S lever already installed, which gives a ready-made quick-detach interface on a spigot-equipped rifle.

What is in the box?
