The Leapers UTG Model 4 Low-Profile Flip-Up Front Sight mounts on the top Picatinny rail of an AR-15 or other long gun. It folds flat out of the way behind an optic and flips up as a backup iron sight when you need it.

The sight is machined from aircraft-grade aluminum with an anodized finish. UTG's Posi-Lock design holds the sight firmly in the up or down position, and a side plunger releases it for folding. The front post adjusts for elevation with a standard 4-prong front sight tool.

Features:

• Mounts on a Picatinny (MIL-STD-1913) top rail
• Low-profile, slim flip-up design
• Posi-Lock with side plunger release
• Elevation-adjustable front post (standard 4-prong tool)
• Aircraft-grade aluminum, anodized
• Fits AR-15 and other Picatinny-railed long guns

A front sight works best when it sits on the same height plane as your rear sight. On a flat-top upper with a free-float rail, check that the rail top lines up with the receiver rail so the sights co-witness. Pair it with a matching flip-up rear sight.

After mounting, tighten the clamp, flip the sight up and down a few times to confirm it locks in both positions, then zero the iron sights at the range before relying on them.
