Magpul Industries MBUS 3 Front Sight OD Green Flip-Up AR-10/AR-15/M4/M16/M110/SR-25

The Magpul MBUS 3 Front Sight condenses Magpul's proven backup-sight design into a compact polymer package built for the AR platform. A spring-loaded flip-up mechanism snaps to standard AR-height when deployed and folds down to a low 0.44-inch profile that clears optics and magnifiers when stowed. The sight clamps directly to any MIL-STD-1913 Picatinny rail without tools for installation.

Tool-less elevation adjustment is delivered on a dual-width enhanced front post similar to the MBUS Pro, with click values of 0.7 MOA and 1 MOA. The impact-resistant polymer body keeps weight to a minimum while absorbing operational abuse in the field, and the smaller footprint preserves valuable real estate on your rail.

Finished in OD Green, this Front sight fits the broadest range of AR-pattern rifles including AR-10, AR-15, M4, M16, M110, and SR-25. Pair it with the matching Magpul MBUS 3 Rear Sight for a complete low-profile backup sight setup that stays tucked out of the way until you need it.
