AR15 / M16 Flip Up Front Sight

The UTG AR15 / M16 Flip Up Front Sight (MNT-755) is a low-profile, deployable backup iron sight built for AR-platform rifles and any long gun running a Picatinny or Weaver rail. CNC-machined from 6061-T6 aircraft-grade aluminum with steel internals and a matte black anodized finish, it features a standard elevation-adjustable A2 front sight post and a spring-loaded posi-lock plunger that snaps the sight up and holds zero through repeated cycles. A 3mm locking bolt clamps it down tight on flat-top uppers, free-float handguards, or gas block rails. It's a solid choice for shooters building out a clean BUIS setup alongside a red dot or magnified optic.

Description

Features

  1. Low-Profile Super Slim Design — Compact footprint pairs with flat-top uppers and same-plane rear sights without crowding optics or rail real estate.
  2. Standard A2 Front Sight Post — Elevation-adjustable A2 post works with any standard 4-prong front sight adjustment tool for familiar zeroing.
  3. Spring-Loaded Posi-Lock Deployment — Side plunger release snaps the sight up and locks it in place; compress the plunger to fold it down when not in use.
  4. Ball-Bearing Zero Retention — Spring-activated ball bearing coupled with the posi-lock plunger holds zero through repeated deployments.
  5. Aircraft-Grade Aluminum and Steel Build — CNC-machined 6061-T6 aluminum body with steel internals finished in matte black hard anodize.
  6. Picatinny / Weaver Mount — Low-profile 3mm locking bolt and mounting deck clamp securely to any Mil-Std 1913 Picatinny or Weaver rail.
  7. AR-15 / M16 / M4 Compatibility — Drops onto flat-top AR-platform uppers, free-float handguards, and gas block rails for a true BUIS setup.
  8. Compact Dimensions — Measures roughly 1.24" L x 1.3" W x 1.8" H and weighs just 1.3 oz, adding minimal bulk to the rifle.
  9. Pairs With UTG MNT-955 Rear Sight — Designed to match the UTG Super Slim flip-up rear on the same plane for a clean, low-profile iron sight pair.

    I know the UTG haters are gonna come out of the woodwork but this little flip up front sight is legit. Machined aluminum, not polymer, and the posi-lock mechanism snaps up solid with zero wobble. Paired it with the matching UTG rear on my 16" midlength build and co-witnessed it with my Sig Romeo5. Zeroed in about 10 rounds.

    Spring loaded posi-lock snaps up tight with no play

    You need a standard 4-prong sight tool to adjust elevation, dosent come with one

    The UTG flip‑up sight folds flush against the rail and stays perfectly aligned when I raise it. It’s lightweight and built like a tank, so I trust it for every range session.

    Low‑profile design won’t snag on gear

    This flip up front sight locks into place with a satisfying click and holds zero really well even after flipping it up and down repeatedly. This thing feels sturdy and the low profile design keeps it out of the way when I'm using my red dot.

    works well and stores away small

    Overall Rating

    I bought a DPMS ORC as a range burner and this is what I use on it. It has improved my iron sight skills quite a bit.
