Magpul MBUS Gen II Front Backup Sight – Picatinny Rail Mount | Gray (MAG247-GRY)

Upgrade your AR-15 or M16 with the Magpul MBUS Gen II Front Backup Sight in Gray (MAG247-GRY) — a reliable, lightweight folding sight engineered for serious shooters who demand performance without the premium price tag.

Built from impact-resistant polymer right here in the U.S.A., the MBUS Gen II is designed to take a beating and keep on working. The spring-loaded flip-up design activates instantly from either side or by pressing the top, while detent and spring pressure holds the sight firmly erect during use — yet allows it to fold flat under impact, keeping your primary optic clear when the sight is stowed.

Compatible with most MIL-STD-1913 Picatinny and STANAG 4694 railed handguards, this front sight delivers the same height-over-bore as standard A2 iron sights, making it a seamless drop-in backup option. Protective wings shield the spring-locking A2-style front sight post, and elevation adjustment is tool-assisted — an elevation adjustment tool is included, though most standard aftermarket A2 front sight tools are also compatible.

Whether you’re building a new rifle or adding redundancy to an optics-equipped setup, the MBUS Gen II Front Sight is a trusted, proven choice at a price that won’t break the bank.
