DCA Enhanced Optic Backup Sights, Glock

DCA Enhanced Optic Backup Iron Sights for Glock

Purpose built backup iron sights for shooters running a slide mounted red dot. Engineered to give you a usable co witness sight picture when the optic goes down, without crowding the dot during normal use. Choose the height that matches your slide and optic.

Choose Your Height

• Optic Cut Height. For 0.125" direct milled optic cuts running RMR footprint optics (Trijicon RMR, Holosun 507C, EPS Carry). Delivers a lower 1/3 co witness on standard deck optics and a 1/4 co witness under tall deck optics.
• MOS Tall Deck Height. For factory MOS slides and milled slides running tall deck optics such as the RMR HD and RCR. Delivers a true 1/3 co witness through the optic window.

Build

• CNC machined from 4140 steel
• Black nitride finish for corrosion and wear resistance
• Fully serrated rear face to cut glare and sharpen the sight picture
• Set screw retention on both front and rear to prevent drift under recoil
• Made in the USA

Compatibility

Fits standard frame Glock slides (17, 19, 22, 23, 34, 45, 47, 49 and equivalents) with factory dovetail cuts. Does not fit Glock 42, 43, 43X, or 48. For custom slide milling and optic cuts, see our Slide Milling and Optic Cuts service.
