Description
The Faxon Firearms Sentry is a complete AR-15 lower receiver built around a 7075-T6 forged aluminum foundation, machined to mil-spec dimensions for broad parts compatibility. Made in the USA, this multi-caliber lower serves as a versatile base for custom AR-15 rifle and pistol builds, accepting any standard-pattern upper.
The forged lower wears a black Cerakote finish for corrosion and wear resistance. An integrated upper/lower tensioning screw draws the two halves together for a tighter, more precise fit compared to standard receiver mating. As a serialized component, FFL transfer is required for purchase.
This complete lower ships fully assembled with B5 Systems furniture installed, including a B5 adjustable carbine stock and B5 pistol grip. Fire control is handled by a Hiperfire EDT3 trigger, giving the build a premium out-of-the-box feel. Complete lower receiver only; no magazine is included.
DISCLAIMER: Firearms and receivers are subject to state-specific shipping restrictions and must be transferred through a valid FFL dealer. Please visit our shipping restrictions page to review all applicable restrictions for your state. Subject to change.
