• Charging handle is ambidextrous, non-reciprocating, foldable, spring returned and is easily relocated from left to right side without tools by the operator.

• The ARAK-21® system allows for a folding stock to be added, as the recoil system does not extend beyond the upper receiver to fully operate.  This eliminates the noise and feel of the buffer tube cycling back and forth.

• Long stroke variable setting gas piston system.  There are three options for gas flow, and one for no gas flow.  This allows for single shot operation.  There is also a clean out port for the gas block between the gas cylinder, and the barrel.

Gas piston actuated, complete upper receiver assembly designed to seamlessly interface with standard AR-15 platform. The ARAK-21® upper receiver offers you all its features with no change to your current lower receiver and can be installed in less than one minute with no tools.
