Stag 15 Tactical 10.5" uppers are chambered in 5.56 NATO and built around a 10.5" 1/7 twist barrel, Stag 9" M-LOK SL Handguard and 7075 T6 Aluminum receivers. These uppers use a carbine-length gas system that is combined with a low-profile gas block, which provides reliability under any condition.

The free-floating Stag 9" 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 upper half does not include a BCG or Charging Handle.

    Quality is a big thing for me, I’m also very picky, but if this please me I’m sure it will please anyone else. There is nothing cheap about this upper at all, I bought their 7.5 inch Ar-15 pistol but it was too small for my liking, so I upgraded to the 10.5 inch and haven’t looked back since. I personally believe this is the best size for an Ar-15 pistol, not too big or small and looks just right with an angled foregrip, mbus gen 2 sights, a stream light hlx mounted topped off with a trijicon 4x32 acog chevron

    Works great and good quality. Fitting matched up perfectly with the Stag arms lower I already had.
