Strike Industries AR-15 Lower Receiver Pin Gunsmith Kit - Precision Parts for AR-15 Maintenance and Assembly

Building or maintaining AR-15 platforms means keeping spare pins and detents on hand—and the Strike Industries AR-15 Lower Receiver Pin Gunsmith Kit delivers exactly what you need in one organized package. Whether you're assembling a stripped lower receiver from scratch, replacing worn components, or stocking a reliable spare parts inventory, this kit bundles the essential pins and detents that keep your rifle running. Designed to industry standards and finished in matte black, these are the small parts that matter when you need them most.

This kit covers the full spectrum of lower receiver pins and detents you'll encounter during assembly or repair. You get multiples of each type so you have spares for future builds or replacements without hunting down individual components. That's the practical thinking behind a gunsmith kit—anticipate what breaks, what wears, and what you'll need when you need it.

The kit's appeal lies in its completeness and convenience. Instead of sourcing takedown pins, pivot pins, hammer and trigger pins, buffer retainer pins, bolt catch plungers, and detents from different suppliers, everything arrives together. Durable construction means these parts will hold up through multiple builds and years of use. For anyone serious about AR platform maintenance or planning their next lower receiver assembly, this kit eliminates the friction of part sourcing and keeps your gunsmith bench ready to go.
