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 in a feature-packed back-up sight system. Significantly reduced in size from the MBUS, it sits at just 0.47" high when folded, 1.38" at its widest point, and weighs a scant 25 grams with hardware. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Front Sight is constructed of our impact-resistant polymer, making it lightweight and extremely durable. Featuring the same spring-loaded technology as its predecessor, they can be deployed with an ambidextrous push-button. The MBUS 3 Front Sight sits at standard AR-height when deployed and includes tool-less elevation adjustment of a dual width enhanced front post similar to the MBUS Pro. MBUS 3 Sights will be available in Black, Flat Dark Earth, and OD Green. Made in the USA.

  • Full-featured spring-loaded flip up sight: Tool-less elevation adjustment and dual width enhanced front sight post, similar to MBUS Pro. 0.47" high when folded and 1.38" wide at widest point. Standard AR-height when deployed
  • Impact-resistant polymer construction: Polymer construction, smaller size provides light weight and resists operational abuse
  • Clamps to most MIL-STD-1913 picatinny rails

MPBS 3

Never been disappointed with MAGPUL. Love how the MBUS 3 is shaved down and minimized compared to the first gen. They seem to be built very robust and to the same quality as all the products I have gotten from MAGPUL.

Yes, I recommend this product.

Mixing Gens

Purchased to replace a lost 1st Gen front sight. Works well with the 1st Gen rear sight. Smaller footprint (nice!) different activation method.

Yes, I recommend this product.

New sights with push bottom in the middle

6 months ago
Like these new sights with the push bottom in the center rather than on the outside, although I never had an issue with the older ones.

Yes, I recommend this product.
