Barska Tactical Front Flip-Up Iron Sight for Rifles and Firearms

A solid backup iron sight setup starts with a reliable front post, and the Barska Tactical Front Flip-Up Iron Sight delivers the kind of dependable aiming tool that belongs on any AR-pattern rifle or Picatinny/Weaver rail system. Whether you're running a dedicated optic and need iron sights as a fail-safe, transitioning between shooting positions, or just want precision aiming options in one package, this flip-up front sight gives you quick access to traditional post-and-aperture shooting without the weight or complexity of fixed sights.

The core of this sight is a square post design with adjustable elevation, letting you fine-tune your zero to match your ammunition, distance, and shooting style. The flip-up mechanism uses a posi-lock design that keeps your sight locked in position once you've dialed it in—no creep, no surprises between trips to the range. Installation is straightforward: a thumb nut secures the sight to your rail, and the quick-detachable design means you can swap it out or stow it if your optic setup changes.

Barska iron sights are built around simplicity and function. You get adjustable elevation for field-correctable zero, a robust flip-up design that stays put, and the kind of no-frills reliability that works equally well at 25 yards or on a longer-range hunt. Pair it with a matching rear sight to complete your backup iron sight (BUIS) kit, or use it standalone if your existing rear sight already covers your needs.
