Samson Quick Flip Front Sight Gas Block Extended Height (A2) Black Hardcoat Anodized for AR-15

The Samson Quick Flip Front Sight Gas Block Extended Height (A2) is a combat-proven flip-up front sight designed for AR-15 platforms where co-witnessing with optics matters and durability under fire is non-negotiable. Built by Samson Manufacturing—a name trusted by military and law enforcement armorers—this front sight integrates directly into your gas block, eliminating the need for a separate Picatinny rail mounted sight. The extended height A2 profile positions your front post at the correct plane to co-witness mid-range scopes and red dots, keeping your backup irons practical and fast to deploy.

Flipping sights up and down is part of rifle life, and Samson's quick-flip design lets you transition between optic and iron in seconds when needed. Whether you're running a precision carbine for distance, a patrol setup for speed, or an all-around rifle that does everything competently, a quality backup front sight earns its real estate on your gun. The hardcoat anodized finish resists wear in the field and stands up to repeated deployment—not a cosmetic upgrade, but armor for a part that actually gets used.

Gas block integration keeps your rail clear for your primary optic and leaves you room to add lights, lasers, or magnified glass without the front sight competing for space. If you're building a serious AR-15 and expect to use your irons, not just paint-fill them for a photo, this is the kind of sight that repays the investment through sheer reliability and proven ergonomics.

Frequently Asked Questions

Will this sight co-witness with my magnified scope or red dot?

Yes. The extended A2 height is designed to position the front post in the correct plane to co-witness with mid-range magnified optics and red-dot sights, keeping your backup irons usable without obstruction.

Does this replace my gas block or mount to it?

This is an integrated gas block sight—it mounts directly to your AR-15 gas tube in place of a standard gas block. You do not need a separate Picatinny-mounted front sight.

What finish is this, and how well does it hold up?

The finish is hardcoat anodized black, a military-grade protective coating that resists corrosion and stands up to repeated deployment and field use better than standard anodizing.

Is this a flip-up or fixed sight?

It's a quick-flip design, meaning you can fold it down to clear your primary optic and flip it back up rapidly when you need to transition to iron sights.
