Tool Free Front Backup Sight – The Next Generation MBUS

Tool Free Adjustment

The Magpul Gen 3 MBUS Front Sight brings the best of both worlds together.  The sleek profile and tool-free design of the steel MBUS Pro, with light weight, low cost, and spring-loaded flip-up mechanism for backup sights exactly when you need them.

*NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed forend on the same plane as the receiver rail. Because of this, the sight is also not compatible with MOE Hand Guards.

Sleek Tool-Free DesignLow Profile when Stowed

Slim Profile and Easy to Adjust

The previous generation MBUS polymer front sight required a tool to adjust elevation.  With the new version, elevation adjustment can be done entirely tool-free with the drum at the center.   And even with that feature, this sight has less bulk, and folds down cleanly over 6 picatinny slots with under half an inch of height.

Specifications

  • Position: Front
  • Height above rail, stowed: 0.44 in.
  • Platform: AR10, AR15, M4, M16, M110, SR25

Elevation Adjustment

~1.6 MOA (1.886″/100m) per click with a 14.5″ sight radius
~1.2 MOA (1.367″/100m) per click with a 20″ sight radius
