LANTAC USA UPS-S Ultimate Takedown Pin Set Black Nitride - AR-15

The LANTAC USA UPS-S Ultimate Takedown Pin Set is a precision-engineered AR-15 lower parts upgrade that replaces the factory pivot and takedown pins with a system designed for faster, frustration-free field stripping. Machined from 17-4PH stainless steel in H900 condition and finished in QPQ black nitride, the UPS-S delivers outstanding wear resistance, corrosion protection, and a clean, professional appearance.

The patent-pending UPS (Ultimate Pin Set) design allows the user to install and remove the AR-15 pivot pin quickly and easily, eliminating the headaches often associated with the standard spring-loaded factory pins. The kit includes both the front pivot pin and rear takedown pin, complete with KNS detents and stainless steel detent springs for a true drop-in installation on any mil-spec AR-15 lower receiver.

Weighing in at .25 oz for the pivot pin and .20 oz for the takedown pin, the UPS-S provides a solid, quality-in-hand feel that reflects its precision machining. Proudly made in the USA by LANTAC USA, this takedown pin set is a smart, low-profile upgrade for any AR-15 build, replacement, or routine service project.
