AT3 Tactical Complete LR AR-15 Lower Receiver – FAB Defense Furniture

Built to Order – Ships Within 3 Business Days

Features

Assembled complete AR-15 lower receiver built on the AT3 AT-15 forged 7075-T6 aluminum lower
FAB Defense RAPS stock adds adjustable length of pull and cheek height for dialing in fit behind magnified optics
FAB Defense Gradus grip gives the lower a more vertical grip angle for supported, prone, or bench shooting positions
Includes installed AT3 Tactical Nickel Boron 4.5lb 2-Stage AR-15 Trigger for a smoother, more controlled trigger press than a basic mil-spec fire control group
Uses a rifle-length fixed buffer tube kit instead of a 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 combines standard lower controls with the AT3 Tactical Nickel Boron 4.5lb 2-Stage AR-15 Trigger, FAB Defense Gradus grip, FAB Defense RAPS stock, and rifle buffer tube kit for a precision-oriented lower setup built around shooter fit and supported-position control.

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.
