FU Tritium Front Blacked Out Rear Suppressor Height Iron Sights for Glock

Upgrade your Glock pistol with Freedom Unlimited Tritium Front Blacked Out Rear Suppressor Height Iron Sights, precision-machined for durability, reliable performance, and enhanced low-light visibility. These aftermarket Glock iron sights feature a self-illuminating tritium front sight paired with a blacked-out rear sight, providing a clean, distraction-free sight picture for everyday carry, target shooting, and custom Glock builds equipped with suppressors or red dot optics.

Constructed from durable 4140 steel with a corrosion-resistant black nitride finish, these Glock front and rear iron sights offer rugged construction and long-lasting reliability. The elevated suppressor-height configuration is designed to provide additional sight clearance for compatible suppressor setups and backup iron sight visibility with compatible slide-mounted red dot optics. Combining tritium front sight illumination with a non-illuminated black rear sight, Freedom Unlimited Iron Sights provide enhanced front sight visibility in low-light environments without requiring batteries or external charging.
