MBUS® 3 - Flip Up Rear Sight - Black - 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 0.55 inches tall when folded, 1.38 inches at its widest point, and weighs just 30 grams with hardware. Its aesthetic is derived from the MBUS Pro, but the MBUS 3 Rear 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 rear sight sits at standard AR height when deployed and includes a windage-adjustable quick-select aperture system.

Made in the USA.
