Samson True Back Up Rear Sight - SMC-02-00057-01

Since these backup sights were never meant to be the primary aiming system, we did away with the dual apertures and went with a single .160 aperture which is small enough for accurate shooting yet large enough to still be of use in low-light environments. Sights lock in both the folded and deployed positions. The durable construction and solid mounting system guarantees you'll stay on-zero.
