 These PAMAX Tactical BUIS PT-90S Degree Angle Sights offer extreme reliability and durability in the field.  Built specifically for Rifle Platforms these sights hold zero and feature a range of specifications designed to the operator’s needs. Machined from lightweight and durable aircraft aluminum. Our PT-90S BUIS Sights provide independent sight picture from primary optic. Sights feature a heavy duty mount screw for extended reliability over time. A spring retention "push to activate" flip-up design allows for rapid deployment and transition from primary optic. Both Front and Rear Sights provide a positive lock when deployed and require a manual press to refold sights to deployment position. Front Sight

Rear Sight dual aperture for low light shooting conditions also features positive retention when deployed. Weighs 1.9 oz.
