MBUS® 3 - Flip Up Front Sight - FDE - MAGPUL

The next evolution in our MBUS (Magpul Back-Up Sight) line, the MBUS 3 incorporates the best features, strengths and value of our original MBUS and MBUS Pro Sights into a feature-rich backup sight system.

Significantly smaller in size than the MBUS, it stands just 0.47 inches tall when folded, 1.38 inches at its widest point, and weighs just 25 grams with hardware. Its aesthetic is derived from the MBUS Pro, but the MBUS 3 Front Sight is constructed with our impact-resistant polymer, making it lightweight and extremely durable. Featuring the same spring technology as the previous model, they can be activated with an ambidextrous button.

The MBUS 3 front sight sits at standard AR height when deployed and includes tool-free elevation adjustment of an improved double-wide front post similar to the MBUS Pro.

Made in the USA.
