Slimmer and Lighter – Better Performance!

The Magpul ACS-L Carbine Storage Stock – Commercial-Spec is a slimmer and lighter drop-in replacement buttstock for AR15/M16 carbines using Commercial-Spec sized receiver extension tubes. Designed with an integral storage compartment in the butt of the stock that can provide multiple storage options.

Similar to the Magpul CTR, the Magpul ACS-L Carbine Storage Stock – Commercial-Spec also features a streamlined anti-snag release latch to prevent accidental activation along with a supplemental friction lock system that minimizes excessive stock movement for enhanced weapon stability and accuracy.

Adds More Maneuverability

The Magpul ACS-L Carbine Storage Stock – Commercial-Spec is the slimmer version of the ACS that utilizes the same center storage compartment and cheek weld but removes the battery tubes for a slimmer, lighter weight package.

It also has a more comfortable stance along with a rubber butt pad to increase impact protection and promotes easier shoulder transitions for better control and accuracy while shooting. This Buttstock adds more maneuverability as well as great functionality for storing your other accessories.
