After seeing questions asked and answered about the various Accuracy International Chassis System (AICS) offerings sporadically posted, and having asked and then fielded those same questions myself, figure it would be a good idea to start a singular centralized thread to document the history and details of the AICS.
Over the course of this thread, I plan to cover the original AICS, the later revised “small bolt handle notch” AICS, the AT AICS, and both the pre and post 2014 AX AICS.
Let’s start with the original AICS, commonly referred to as the Legacy AICS. This chassis was based on the classic Arctic Warfare (AW) chassis frame with thumbhole skins/stock sides. The Lagacy AICS came in three standard configurations:
1.0 - Fixed stock, fixed cheek
1.5 - Fixed stock, adjustable cheek
2.0 - Folding stock, adjustable cheek
Of course, there are the oddball configurations, such as 2.0 rear skins with fixed cheek.
Before going into the standard configuration Legacy AICS models, let’s start with a less common original first version of the 1.0:
This is the original AICS as when it was first released, and only made as such for a year or two before changes were made to the eventual Legacy AICS as most are familiar with. These original first versions of the Legacy AICS are identified by two main differences, a completely welded chassis frame and a fully swept back bolt handle notch:
And as everyone is already aware of Accuracy International’s color inconsistency, the older green skins were a shinier and more olive drab green compared to the later green Legacy AICS skins:
Similar breakdowns of the other AI chassis systems to follow if there’s interest.
