Flip-Up Design and Elevation Control

This polymer sight flips up when you need it and stays out of the way when you don't. The standard elevation adjustment lets you dial in your zero without tools or guesswork—each click moves your point of impact 0.25 MOA. Lightweight polymer construction keeps weight down while maintaining durability. If you're building a rifle or pistol platform, backup sights pair well with modern setups.

Frequently asked questions

Will this flip-up sight cowitness with my red dot optic?

Mission First Tactical designs these sights to sit lower than cowitness height. They work best as true backup sights, staying clear of your optic's line of sight when mounted and flipped down.

How durable is polymer construction for a backup sight?

Polymer holds up well for backup use. It's lighter than steel and resists corrosion. Since backup sights see less regular use than primary optics, durability is solid for the price point.
