Magpul Industries MBUS Gen 2 Rear Flip-Up Sight for AR-15/M16, Black Polymer, Picatinny - MAG248BLK

Product Description

The Magpul MBUS Gen 2 Rear Sight is a rugged, spring‑loaded back‑up sight designed for AR‑15/M16 platforms and other firearms equipped with a 1913 Picatinny rail. Built from high‑strength, color‑injection molded polymer, it deploys instantly from either side and locks positively into place. Protective wings shield the dual, same‑plane apertures, and the large windage knob provides tool‑free adjustments. Engineered to withstand hard use, the sight stays put under recoil yet folds flat if impacted. Made in the USA.
