The Magpul MBUS Pro Offset Front is an all-steel 45° offset backup iron sight, clamping to any 1913 Picatinny rail alongside a primary optic.
The Magpul MBUS Pro Offset Front Sight (MAG525) mounts at a fixed 45° angle beside your primary optic. Roll the rifle, and a complete iron sight picture is waiting — no dialing magnification down, no flipping mounts, no compromise to your scope's zero. For precision rifles and LPVO builds that occasionally need to work fast and close, offset irons are the cleanest answer, and the MBUS Pro is the benchmark execution.
Machined steel construction with a corrosion-resistant finish gives the folded sight a tiny, snag-free footprint and a lockup with zero play when deployed. It survives the barricade knocks and case drops that break polymer offsets, and it returns to zero every single time.
Key Features
- 45° offset geometry: transition to irons with a roll of the rifle
- All-steel construction: hard-use durability at a hard-use angle
- Minimal folded footprint: stays clear of optics and hands
- True return to zero: positive, play-free lockup
- Ideal for LPVO and precision builds: speed without sacrificing the scope
Compatibility & Fitment
Clamps to a 1913 Picatinny rail and sits at 45° so it works alongside a primary optic instead of beneath it. It needs a clear stretch of top rail forward of your optic mount. Pair it with the MBUS Pro Offset Rear (MAG526) at the same angle on the same rail plane, zero at your chosen close-range distance, and train the roll.

Frequently Asked Questions
How does the offset front sight mount?
The MAG525 clamps to a 1913 Picatinny rail and sits at 45 degrees so it works alongside a primary optic instead of beneath it. It needs a clear stretch of top rail forward of your optic mount. It is designed to pair with the MBUS Pro Offset Rear (MAG526).
When would I want offset irons rather than standard flip-ups?
Offset sights are the usual choice when a magnified optic takes up the centerline and you still want irons for close targets. You roll the rifle 45 degrees and the sight picture is there without touching the optic. Standard flip-ups only make sense when the optic sits low enough to see over or through.
What is it made from and does it fold away?
It is all steel with a black finish and folds flat against the rail when not in use. Steel gives it more resistance to knocks than a polymer sight, at the cost of a little weight. Maintenance is limited to keeping the hinge clean and checking the mounting screw stays tight.
Do I need to buy the rear at the same time?
Yes, an offset front needs the matching offset rear at the same angle to give a usable sight picture. There is no color choice, as the MBUS Pro range is black steel.
