The Armaspec Spare Parts Kit (brand part no. ARM148-SS) bundles the small, easy-to-lose detent parts every AR15/AR10 owner eventually needs into one convenient kit. Rather than tracking down individual pivot pin detents, springs, and catches from a parts bin, this kit covers the essentials in a single purchase, making it a smart addition to any range bag or armorer’s kit. It is built for AR15 and AR10 platforms alike, so one kit covers both calibers of build.
