Tool Free Front Backup Sight – The Next Generation MBUS
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.

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.
