Yhm Flip Front Sight Tower W/lug Asy

The Yankee Hill Machine flip-up front sight tower is a purpose-built tactical iron sight for AR-15s that combines the speed and reliability of exposed sights with the clean profile of folding optics. Whether you're running a primary optic and need a backup, or you prefer iron sights as your main aiming system, this flip-up front sight tower delivers all-steel construction tough enough for serious use—hunting, competition, duty, or the range. The push-button deployment locks solidly into place when raised, and folds flat when not needed, keeping your rifle's sight picture uncluttered.

Built to accept standard AR-15 front sight posts and hardware (included), the tower mounts securely to your upper receiver or rail using four cap screws and a 7/64" Allen wrench. The two-piece design is especially handy if you've got a pinned-and-welded muzzle brake or suppressor—it'll work with those setups without interference. The round hooded front sight guard lets you acquire targets quickly while protecting the post from dings and snags that come with real-world use.

At the weight of a standard fixed tower sight, there's no penalty for adding this to your fighting rifle. You get flip convenience without dragging your balance or handling characteristics. All-steel construction means it'll hold zero through thousands of rounds and hard use. If your setup calls for a rugged, reliable backup sight or your primary aiming system, this is iron-sight fundamentals done right.

Frequently Asked Questions

Will this flip-up front sight work with my pinned-and-welded muzzle device?

Yes. The two-piece design of this Yankee Hill Machine tower allows it to mount on firearms with pinned and welded muzzle accessories without interference.

What hardware is included with the sight tower?

The sight comes with standard AR-15 sight post hardware. You'll need a 7/64" Allen wrench for installation of the four mounting cap screws.

Is this a backup sight for an optic, or can I use it as a primary aiming system?

The flip-up design works for either role—as a reliable backup iron sight behind a scope or red dot, or as your primary aiming system. All-steel construction and a solid lock-up make it suitable for either application.

How much does the flip-up mechanism add to the weight of my rifle?

This sight tower weighs the same as a standard fixed AR-15 front sight tower, so there's no additional weight penalty for the flip functionality.
