Frequently Asked Questions
Will these sights co-witness with my red dot or holographic optic?
Yes. The HiViz Folding AR Back Up Sights are designed with a low-profile folding format that allows absolute and lower one-third co-witnessing with most popular red dot and holographic optics when mounted on a standard Picatinny rail. Always verify the height of your specific optic to confirm the co-witness alignment before finalizing your setup.
Are these sights compatible with all AR-15 pattern rifles?
These sights are compatible with any AR-15 or modern sporting rifle (MSR) that features a standard MIL-STD-1913 Picatinny or Weaver-style top rail. They are not designed for rifles with fixed carry handles or non-railed handguards without an additional rail adapter. If your rifle has a flat-top upper receiver, these sights should mount directly with no modifications required.
How do I zero and adjust these backup iron sights?
The HiViz Folding AR BUIS offer tool-free or minimal-tool windage and elevation adjustments depending on the sight. For best results, start by mounting both the front and rear sights on your rail and confirm they are level. Use a 25-yard or 50-yard zero target to make initial adjustments, then confirm your zero at your preferred distance (typically 50 or 100 yards for AR-platform rifles). Consult the included instruction sheet for click-value specifications and adjustment directions.
