Magpul MBUS Gen 2 Front Sight MAG247-GRY

Magpul MBUS Generation 2 Front Sight

The MBUS (Magpul Back-Up Sight) represents one of the most trusted backup iron sight solutions for modern AR-platform rifles. This front sight combines affordability, durability, and proven performance in a lightweight polymer package.

Key Features

Construction & Design

• Impact-resistant polymer construction resists operational abuse and keeps weight minimal
• Spring-loaded flip-up mechanism activates easily from either side or via top release button
• Protective wings shield the A2-style front sight post from damage
• Elevation adjustable to match your specific rifle configuration

Performance & Compatibility

• Mounts to MIL-STD-1913 Picatinny rails on most AR-platform handguards
• Provides the same height-over-bore as standard A2 front sights
• Precision elevation adjustments: 1.6 MOA per click (14.5" sight radius) or 1.2 MOA per click (20.0" sight radius)
• Elevation adjustment tool included

Practical Advantages

• Folds flat when not in use, remaining out of the way until needed
• Detent and spring pressure keep the sight erect during use but allow unobstructed folding under impact
• Made in the USA

Important Mounting Notes

The MBUS front sight must mount to a railed foreend on the same plane as the receiver rail. It is not compatible with MOE handguards or railed gas blocks due to heat concerns. Verify your handguard's Picatinny rail configuration before purchase.
