The Accuracy International Chassis System (AICS) can be configured for various actions (all Accuracy International and some Remington 700 receivers), triggers, and other items. The AICS version for Remington 700 receivers was introduced in 1999. The basic variant is the AICS 1.0 with a fixed cheek-piece. The AICS 1.5 variant sports a fully adjustable cheekpiece. The AICS 2.0 is a folding stock that reduces the rifles overall length by 210 mm (8.3 in) when folded and adds 0.2 kg (0.44 lb) weight to the rifles total weight. The AICS 2.0 also has a adjustable cheekpiece that adjusts left/right as well as for height to obtain optimum cheek position when using night vision equipment or telescopic sights with large objective lenses. There is also a quick adjust cheekpiece option that has a spring loaded cheekpiece in conjunction with a quick adjust butt plate.

The AICS side "panels" are made from a high-strength polymer and are available in the colours olive drab, dark earth or black.

Sling attachment points are mounted on each side of the rifle, so it can be carried flat against the back and used comfortably by left and right-handed users. A front attachment point is situated below the fore end and can be used to anchor a target style sling or be replaced by an adapter for a Harris bipod.
