Frequently Asked Questions
Will the YHM Flip Rear Sight co-witness with my existing front sight post?
Yes. The YHM Flip Rear Sight is specifically designed to co-witness with the standard M16/M4-style front sight post found on most AR-15 platforms. This means when both sights are deployed, they align correctly through a standard lower-third or absolute co-witness with most red dot optics mounted at the appropriate height.
Is this sight compatible with my non-AR-15 rifle or carbine?
The YHM Flip Rear Sight mounts to any standard Picatinny (MIL-STD-1913) rail, so it can be installed on virtually any rifle, carbine, or shotgun that features a Picatinny rail on the receiver or hand guard — not just AR-15 platforms. Keep in mind that co-witness height is optimized for M16/M4-style front sights.
Does the sight stay securely in the up position during firing?
Absolutely. The YHM Flip Rear Sight is engineered to lock firmly in the deployed position, preventing movement or collapse under recoil. The steel base provides a solid foundation while the quick-release thumb screw keeps the entire unit anchored to the rail, ensuring your zero holds shot after shot.
