Description
Building an AR-15 lower from scratch or restoring a stripped receiver requires a reliable set of components that actually meet military dimensional standards rather than merely claiming to. KAK Industry produces the parts in this kit in-house, which means the tolerances are consistent across the group rather than sourced from a patchwork of third-party suppliers and assembled into a bag.
The trigger group is mil-spec geometry, so it will work with any standard mil-spec hammer, trigger, and selector you already own and will drop into any mil-spec lower receiver without fitting. The included trigger guard is machined from billet rather than stamped, giving it a more substantial feel and sharper edges than a typical stamped unit. The grip is a standard A2 pattern, which suits shooters who want a proven, familiar geometry without any additional cost built in for an upgrade they may not want.
Springs are black oxide finished, which provides a degree of corrosion resistance while keeping the spring rates consistent with mil-spec values. The entire kit is made in the United States. For a builder who wants a dependable, no-compromise starting point without sorting through mixed-origin components, this kit covers the complete lower parts group and leaves room in the budget for whatever trigger or grip upgrade comes next.
