This upper receiver is side-folding compatible and features Matador Arms® patent-pending EZTS™ “Easy Take-down System” with no tools required to break down the upper for maintenance and cleaning.  The Extended Rail System (ERS) is included and pre-installed on this upper receiver, to extend the handguard over the 16″ barrel.

The ERS is M-LOK compatible throughout to extend the accessorization of the upper receiver with lights, lasers, optics, etc.
