The 1911 U-Notch Rear Sight by 10-8 PERFORMANCE LLC is made from heat-hardened 4140 steel for durability, with a dehorned design to prevent snagging during draw.
It features a U-shaped notch for quick sight alignment with various front sights and has serrations for a glare-free picture, plus a ledge for one-hand cocking.
Designed to fit Novak-style dovetails, the sight has a manganese phosphate parkerized finish for wear resistance and includes a setscrew for secure mounting.
