Armaspec ARM148-SS Spare Parts Kit AR-15/AR-10 Lower Parts Stainless Steel

The Armaspec ARM148-SS Spare Parts Kit is a compact stainless steel replacement parts kit designed for AR-15 and AR-10 lower receivers. Purpose-built as an "oops" or bench-stock kit, it supplies the small springs and detents that are easy to lose or damage during field stripping, installation, or armorers' work.

This kit fits 5.56/.223 and 7.62/.308 AR-pattern lowers and is Made in the USA by Armaspec. The stainless steel components deliver corrosion resistance, making this kit ideal for long-term storage so a missing detent or spring never sidelines a build or a range trip. Backed by Armaspec's lifetime warranty, it is a practical add-on for armorers, gunsmiths, and home builders who want the critical small parts on hand.

Kit includes multiple stainless steel takedown detents, pivot pin detents, and associated springs to replace the small hardware most often lost when working on an AR lower.
