NcStar Pro AR Flip-Up Front Iron Sight for AR-15
The NcStar Pro AR Flip-Up Front Sight is a precision-engineered backup iron sight (BUIS) designed to keep your AR-platform rifle mission-ready when your primary optic fails or needs to be bypassed.
- Spring-loaded design deploys instantly with a single push of a button
- Low-profile fold-down profile clears optics and reduces snag hazards
- Fully adjustable A2 steel front sight post for precise elevation tuning
- Lightweight aluminum body keeps your total rifle weight minimal at 2.0 oz
- Compatible with any Picatinny MIL-STD-1913 rail system out of the box
- Includes a mounting tool for secure, tool-assisted installation
Who This Is For
This flip-up front sight is ideal for AR-15 and AR-10 owners who run a primary optic — red dot, LPVO, or magnified scope — and want a reliable, co-witnessed backup iron sight system. It's equally well-suited for competition shooters, home defenders, and range enthusiasts who demand a low-profile BUIS that won't interfere with everyday handling but snaps into action the moment it's needed.

Frequently Asked Questions
Will this flip-up front sight co-witness with my red dot or holographic sight?
Yes — the NcStar Pro AR Flip-Up Front Sight is designed for use as a backup iron sight alongside optics. When paired with a compatible flip-up rear sight, it can achieve both absolute and lower-one-third co-witness depending on your optic's mount height. Always verify co-witness height compatibility with your specific red dot or holographic sight before purchasing.
Is this sight compatible with both AR-15 and AR-10 rifles?
This sight mounts to any Picatinny MIL-STD-1913 rail, making it compatible with AR-15, AR-10, and virtually any other rifle or carbine that features a standard Picatinny rail on the handguard or gas block area. It is not designed for fixed A2-style front sight towers without an accessory rail.
How is elevation adjusted on the A2 front sight post?
The steel A2 front sight post is adjusted for elevation using the included mounting tool (or a standard A2 front sight tool). Rotating the post clockwise raises the point of impact, while counterclockwise rotation lowers it. This allows precise zeroing at your preferred distance without requiring additional tools or gunsmithing.
