The AR-15 Flip-Up Front Sight - Back-Up Iron Sight is a versatile and reliable option for shooters who want a secondary sighting system to complement their optics. Designed to be mounted on gas blocks with Picatinny rails that are lower than the receiver rail, this flip-up sight provides a solid backup in case your primary optic fails or is not usable.

Key Features:

• Mounting Compatibility: Specifically designed to be installed on gas blocks with Picatinny rails that sit lower than the AR-15's receiver rail.
• Flip-Up A2 Front Sight Post: Folds down when not in use, keeping it out of your optic’s view for an uncluttered sight picture. When needed, it can quickly be flipped up for immediate use.
• Adjustable Elevation: The A2 front sight post is fully adjustable for elevation, allowing for precise targeting adjustments.
• Durable Construction: Made from a combination of aluminum and steel, the sight is lightweight but tough enough to withstand the rigors of field use.

Specifications:

• Length:
  • 1.2" (when extended)
  • 2.1" (when folded down)
• Weight: 3.4 oz

This flip-up sight is a reliable backup option for AR-15 shooters, ensuring that even if your optic fails, you can still maintain accurate shooting performance with adjustable iron sights.
