Rather than a traditional wooden or polymer rifle stock, the AW is based on an aluminium chassis which extends the entire length of the stock.
This chassis system is marketed as the Accuracy International Chassis System (AICS) and can be used for all Accuracy International rifles.
All other components, including the receiver, are bolted directly to this chassis.
Two hollow polymer "half thumb-hole stock panels", usually coloured green, dark earth or black, are in turn bolted to each other through the chassis, creating a rugged yet, for its sturdiness, comparatively light weapon.

The Accuracy International receiver is bolted with four screws and permanently bonded with epoxy material to the aluminium chassis, and was designed for ruggedness, simplicity and ease of operation.
To this end, the heavy-walled, flat-bottomed, flat-sided receiver is a stressed part, machined in-house by AI from a solid piece of forged carbon steel.
AW rifles are supplied in two action lengths—standard AW (short) and long SM (magnum).
The six bolt lugs, arranged in two rows of three, engage a heat-treated steel locking ring insert pinned inside the front bridge of the action.
The ring can be removed and replaced to refresh headspace control on older actions.
The AW system cast steel bolt has a 0.75-inch (19.05 mm) diameter combined with gas relief holes in a 0.785 in (19.9 mm) diameter bolt body and front action bridge allowing high-pressure gases a channel of escape in the event of a cartridge-case head failure.
Against penetrating water or dirt the bolt has milled slots, which also prevent freezing or similar disturbances.
Unlike conventional bolt-action rifles, the bolt handle is bent to the rear, which eases the repeating procedure for the operator and reduces the contour of the weapon.
The action cocks on opening with a short, 60 degree bolt throw and has a non-rotating (fixed) external extractor and an internal ejector.
Firing pin travel is 0.26 in (6.6 mm) to keep lock times to a minimum.
Finally, an 11 mm (0.43 in) integral dovetail rail located above the receiver is designed to accommodate different types of optical or electro-optical sights.
As an option, a MIL-STD-1913 rail (Picatinny rail) can be permanently pinned, bonded and bolted to the action, providing a standard interface for many optical systems.
