Features

Assembled complete AR-15 lower receiver built on the AT3 AT-15 forged 7075-T6 aluminum lower
UTG Ultra Slim pistol grip gives the lower a narrower grip profile than standard A2-style furniture
UTG Pro Ops Ready S4 stock adds a practical adjustable carbine stock setup for mil-spec buffer tubes
AT-15 lower features mil-spec AR-15 compatibility, “Cal Multi” markings, pictogram safety markings, and a deeper-than-mil-spec flared magwell
Includes installed AT3 GI curved trigger, mil-spec lower controls, STNGR 7075 trigger guard, UTG furniture, and carbine buffer assembly

This complete AR-15 lower receiver is assembled from an AT3-curated parts selection built around function, ease of use, and components commonly purchased together. It pairs standard lower controls and an AT3 GI curved trigger with UTG furniture, giving the lower a slim grip and adjustable stock setup while keeping the rest of the layout familiar and easy to service.

Already have a lower? This same parts package is also available as an unassembled lower build kit without the receiver.

Note: Parts may vary based on availability and may be substituted with components of equal or greater value. Individual branded components are covered by their respective manufacturer warranties.

Warranty Note: Curated by AT3 Tactical. Components in this kit are covered by each manufacturer’s own warranty — AT3’s warranty does not extend to or replace the warranties of the individual parts included. Warranty terms for some component brands may not yet be listed in the warranty tab; contact the manufacturer directly for in-depth and up to date coverage details.
