The Magpul MBUS Pro Hooded Front Sight is an all-steel folding backup iron sight for AR-15 and M4 rifles, clamping to any 1913 Picatinny top rail.
The Magpul MBUS Pro Hooded Front Sight (MAG1518) is machined from steel and finished in a corrosion-resistant black, with a protective hood shielding the post from knocks, drops and hard contact. Where polymer backup sights are an insurance policy, the MBUS Pro is a genuine sighting system: it locks up with zero play, holds zero through abuse, and presents a crisp, clean post the moment it deploys.
Despite the steel construction, the folded profile is remarkably low — slim enough to disappear under optics and co-witness cleanly through red dots. Deployment is instant and positive from either side, and the sight returns to exactly the same zero every time it flips up. This is the front sight for rifles where the optic is the plan and the irons must never be the excuse.
Key Features
- All-steel construction: primary-sight durability in a backup
- Protective hood: shields the post from impact and snags
- Ultra-low folded profile: vanishes under optics, co-witnesses cleanly
- Repeatable return to zero: flips up to the same zero, every time
- Ambidextrous deployment: fast from either hand
Compatibility & Fitment
Fits 1913 Picatinny top rails on AR-15/M4 pattern rifles, so it will sit on a flat-top upper or a rail-topped handguard at the gas block position. You need enough clear rail at the front and the right height relationship with your rear sight. It pairs with any MBUS Pro rear sight — fit, zero, and forget it is there until you need it.

Frequently Asked Questions
What does this sight mount to?
It fits 1913 Picatinny top rails on AR-15/M4 pattern rifles, so it will sit on a flat-top upper or a rail-topped handguard at the gas block position. You need enough clear rail at the front and the right height relationship with your rear sight. It pairs with any MBUS Pro rear sight in the range.
What does the hood add over a plain front sight?
The hood shields the front post from knocks and from side light, which helps keep the post looking the same in changing conditions. It also gives the post some protection if the rifle is dropped or dragged through cover. When folded down the sight stays out of the way of an optic's sight picture.
Is it steel throughout?
Yes, the MBUS Pro range is all steel with a black finish, so it takes hard use rather than relying on polymer. That makes it heavier than a polymer flip-up but far more resistant to being crushed or snagged. Care is simple: keep the hinge clean and lightly oiled.
What else do I need to make a working sight set?
A front sight only works with a matching rear, so pair it with something like the MBUS Pro Rear Sight at the same height standard. This one comes in black only.
