AR-10® A-Series Compact SuperSASS™ Complete Upper Half Assembly


The AR-10 CSASS is the carbine version of its predecessor, the SuperSASS.  It is a lighter weight, versatile and supremely accurate firearm perfect for law enforcement and military support roles.  The adjustable gas system optimizes function with or without a suppressor, and the collapsible buttstock allows for length-of-pull adjustments.

All Armalite complete upper half assemblies include a bolt carrier group and charging handle.

Armalite’s A Series uppers will only work with an Armalite A series lower.

To know if you have an A series rifle or lower look at your serial number.  The serial number will begin with an A, for example A000001
