The Tacfire IS012B Low Profile Polymer Flip-Up Front and Rear Sights are a practical and affordable sighting solution for AR-15, M4, and other Picatinny rail-equipped firearms. This complete set includes both a front and rear flip-up sight, constructed from durable polymer for lightweight performance without sacrificing strength. Designed with a low-profile footprint, these sights remain out of the way when folded down, making them ideal for use with red dot optics, holographic sights, or as reliable backup iron sights (BUIS).
Why Choose the Tacfire IS012B Flip-Up Sights?
The Tacfire IS012B offers shooters a cost-effective way to add quality flip-up iron sights to their rifle. Many modern AR-15 builds rely primarily on red dot or magnified optics, but having dependable backup iron sights is essential for redundancy in case of optic failure. These low-profile polymer sights are engineered to sit close to the rail when folded, minimizing interference with optics while providing a clear sight picture when deployed. The polymer construction keeps weight down, which is especially beneficial for lightweight builds and competition rifles. With a simple push-button or lever deployment system, these sights can be quickly raised into position when needed, offering shooters peace of mind and versatility in any situation.

Performance and Build Quality
The Tacfire IS012B Low Profile Polymer Flip-Up Sights are built to provide reliable backup sighting options for AR-platform rifles. The polymer material offers excellent strength-to-weight ratio while resisting the elements better than some metal alternatives in certain environments. When folded, the sights sit low enough to allow most red dot and holographic sights to co-witness or sit above the iron sights without obstruction. When raised, the sights provide a clear and consistent sight picture for accurate shooting at typical engagement distances. The rear sight features windage adjustment, allowing shooters to properly zero their rifle. These sights are particularly popular among budget-conscious builders, new shooters, and those who want a dependable set of backup irons without adding significant weight or cost to their build.
