Magpul MBUS Pro Front Folding Sight

The backup sight that behaves like a primary — all-steel MBUS Pro engineering in its purest form.

The Magpul MBUS Pro Front Folding Sight (MAG275) is machined from steel, finished in corrosion-resistant black, and built around one uncompromising requirement: when it flips up, it must be exactly where you zeroed it. The lockup is free of play, the detents are positive, and the post presents a crisp sight picture that steel alone can keep true through years of knocks.

Folded, the MBUS Pro sits astonishingly low on the rail — among the slimmest steel sights made — so it disappears under magnified optics and co-witnesses correctly with red dots. Deployment is instant from either side. For duty rifles and serious builds, this is the difference between carrying backup sights and trusting them.

Why shooters choose the MBUS Pro Front

• All-steel construction — durability polymer cannot match
• Lowest-profile steel sight in its class — invisible under optics
• Locks up with zero play — true return to zero, every deployment
• Co-witnesses with red dots — correct height across standard setups
• Ambidextrous, instant deployment
