UPPER RECEIVER PARTS

AR-15 Upper Receiver Parts

Dark Storm Industries offers AR-15 upper receiver parts for new builds, repairs, upgrades, and replacement applications. DSI upper components are used throughout our DS-15 firearms and are designed around standard AR-15 dimensions for compatibility with compatible Mil-Spec AR platforms.

Browse AR-15 barrels, muzzle devices, gas system components, barrel nuts and mounting components, and bolt carrier groups, charging handles, upper parts kits, and other upper receiver components.

Whether you are assembling a complete upper, replacing a worn component, or upgrading an existing AR-15, DSI offers individual upper receiver parts that allow builders and armorers to replace only the components they need.
