San Tan Tactical Lower Parts Kit (Black, No Grip/Trigger) - STT-LPK

The San Tan Tactical Lower Parts Kit gives you a ready-to-assemble foundation for an AR-pattern build without locking you into a specific grip or trigger choice. This black-finished kit includes all the small parts and springs you need to complete a lower receiver, letting you customize the ergonomics and trigger function to match your shooting style—whether you're building a precision rifle, a duty gun, or a do-it-all hunting platform.

San Tan Tactical has built a reputation on solid manufacturing and no-nonsense reliability. This kit reflects that ethos: the components are made to exacting tolerances and finished to last through years of use and maintenance. By excluding the grip and trigger, the STT-LPK gives you the freedom to source those critical parts separately, so you're not paying for components you'd swap out anyway.

Whether you're assembling your first AR or completing another build in your safe, this lower parts kit handles the fiddly work so you can focus on fitting the trigger and grip that feel right to you. It's the kind of part that doesn't make headlines but absolutely matters when you're turning a bare receiver into a functioning rifle.
