The Ruger AR Small Parts Kit is the kind of insurance every AR owner should keep in the range bag or parts drawer. Detents, springs, and the other tiny components of an AR-15 lower have a talent for launching into the shop void during maintenance, and a lost takedown detent can end a build session or range day on the spot. Sourced from Ruger, the maker of the popular AR-556 line, these are factory-quality components that drop into mil-spec pattern lowers. Cheap, small, and exactly what you need the moment you need it, this kit earns its keep the first time a spring goes flying.
