The HD Night Sights were specifically created to address the needs of tactical shooters.

The three dot green tritium night sight set's front sight features a taller blade and an aiming point ringed in photoluminescent paint while the rear sight is outlined in black and features a wider U-shaped notch. This unique configuration increases visibility and quickens front sight acquisition even in transitional lighting.

Additionally, the front surface of the rear sight is steeply hooked to assist in emergency one-handed slide operation.

Green tritium lamps are warranted for 12 years from date of manufacture.


Professional installation recommended.

    The best out there

    The U cut in the rear sight and the yellow front make it quick and easy to pick up with my older RX eyes. I like the yellow over the red because it stands out more to me. BCM quick shipping is just another plus.
