Stag Arms Stag-15 Tactical 5.56 Complete Upper - 7.5" FDE

AR-15 Complete Upper Receiver


Stag 15 Tactical 7.5" upper is chambered in 5.56 NATO and built around a 7.5" 1/7 twist barrel, Stag 7" M-LOK SL Handguard and 7075 T6 Aluminum receivers. This upper uses a pistol-length gas system that is combined with a low-profile gas block, which provides reliability under any condition.


The free-floating Stag 7" M-LOK SL Gen 2 Handguard features a slim, lightweight profile that offers increased ergonomics, maximum airflow, and modularity while continuing to provide the utmost strength and durability. The handguard provides uninterrupted picatinny rail along the top, which allows room for sights, optics and accessories the shooter may require.


This Complete Upper does not include a BCG or Charging Handle.
