Description
Upgrade your Glock slimline pistol with Freedom Unlimited Tritium Front Blacked Out Rear Optic Height Iron Sights, precision-machined for durability, reliable performance, and enhanced low-light visibility. These aftermarket Glock night sights feature a self-illuminating tritium front sight paired with a solid blacked-out rear sight, providing a clean, distraction-free sight picture for everyday carry, target shooting, and custom Glock builds equipped with 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 optic-height configuration features a .305″ front sight designed for lower-third co-witness 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.
