The Lantac Ultimate Takedown Pin Set (brand part number 01-LP-UPS, model UPS-S) upgrades an AR-15’s factory pivot and takedown pins with a matched stainless steel set. Lantac machines the pins from 17-4PH stainless steel in the H900 condition, then finishes them in QPQ nitride black for corrosion resistance and a hard, wear-resistant surface. The set ships complete with KNS-style detents and stainless detent springs, so there’s nothing extra to source, and every part is manufactured in the USA.
