The UTG (Leapers) MNT755 Low Profile Flip-Up Front Sight is a spring-loaded front iron sight designed for AR-15 style platforms and mirrors the footprint of standard A2 front posts. It mounts to Picatinny/Weaver rails on handguards or receivers and features a low-profile, anodized finish for reduced optic obstruction. The sight uses a Posi-Lock deployment system to secure the sight tower when in use.
