The ProMag Flip-Up handguard height front sight is precision machined to fit MIL-STD 1913 Picatinny rails. The sight is mounted to the rail via a locking bar and secured with a cross slotted, knurled thumb screw. The sight is adjustable for elevation and features straight protective ears with an HK-Style profile. The sight's stem folds up and towards the shooter to deploy. When in the up position the sight is locked in place via a spring loaded plunger. To fold the sight to the down position, all the shooter has to do is depress the plunger and fold the sight stem forward. No permanent modification required for installation. All hardware included.
