Frequently Asked Questions
What does "same plane" mean, and why does it matter?
"Same plane" means the flip front sight is designed to sit at the same height as a standard fixed AR-15 front sight post, allowing it to co-witness correctly with a same-plane rear sight. This ensures your sight picture remains accurate and consistent whether your optic is in use or removed, making it a true drop-in backup solution without requiring height adjustments or special rear sights.
Is this compatible with both mil-spec and commercial AR-15 uppers?
Yes. The YHM Flip Front Sight mounts to any standard Picatinny (MIL-STD-1913) rail, which is found on virtually all mil-spec and commercial AR-15 upper receivers and handguards. Installation is tool-free using the included thumb screw, so it fits a wide range of AR-15 builds without modification.
Can I adjust the elevation on this front sight?
Yes. The YHM Flip Front Sight accepts all standard AR-15 sight posts, including the included post, which can be threaded up or down for elevation adjustment just like a fixed A2-style front sight. A standard front sight adjustment tool or bullet tip can be used to make zeroing adjustments quickly in the field.
