UTG Flip-Up Aluminum Front Sight for AR-15 – MNT-757

Are you looking for a reliable, metal sight that will secure your carbine in case of a collimator failure? The UTG Flip-Up Front Sight (model MNT-757) is a professional, low-profile solution in the BUIS (Back-Up Iron Sights) category. Made of aerospace aluminum, it guarantees flawless zero retention and maximum mechanical resistance on the AR-15 platform.

Precision from aerospace aluminum and full vertical adjustment

Unlike basic polymer sights, the UTG MNT-757 front sight is entirely machined from high-strength aerospace aluminum. The metal surface has undergone a hard anodizing process in deep black, which provides extreme resistance to scratches, abrasion, and corrosive atmospheric agents. The front sight has an integrated post with precise vertical adjustment (up/down), allowing for perfect zeroing of the weapon and precise adjustment of the point of impact (POI).

Instant spring-loaded Flip-Up mechanism

Speed of reaction in critical situations is a priority. The UTG front sight is equipped with an intuitive, spring-loaded activation button. A single light press is enough for the sight to instantly and rigidly unfold into the vertical position. In the closed position, the mechanism has a solid, mechanical lock, which guarantees an extremely low-profile mount on the rail. This prevents accidental snagging of the sight on tactical gear, slings, or branches during movement.

Universal compatibility and Co-Witness standard

The MNT-757 model was designed in accordance with military height standards (Mil-Spec Height). This means that when unfolded, it offers perfect co-axiality with:

• Classic rear sights mounted on Carry Handles,

• A wide range of optics and red dot sights (in Absolute or Lower 1/3 Co-Witness standard). Installation is done directly on any Picatinny MIL-STD-1913 rail (on a gas block of equal height with the receiver or on a free-float handguard). A solid mounting screw guarantees a firm attachment to the rail, resistant to powerful vibrations and firearm recoil.

• Construction: Folding (Flip-Up) with position lock.

• Material: Anodized lightweight aircraft aluminum.

• Mounting: Standard 22mm Picatinny rail (allen key included).
