Faxon Firearms Sentry Features The Faxon Firearms Sentry lower is forged from 7075-T6 aluminum giving it the strength and durability builders expect from a mil-spec-pattern AR-15 receiver. Because it is multi-caliber compatible this lower can serve as the foundation for a range of AR-15 builds without requiring a caliber-specific receiver. The Cerakote metal finish adds corrosion resistance and a clean consistent look that holds up to repeated handling and field use. Shipping as a complete lower rather than a stripped receiver saves builders the time and cost of sourcing and installing individual internal components. A B5 adjustable stock paired with a B5 grip completes the rear assembly giving shooters a comfortable ergonomic platform right out of the box. The black synthetic furniture is lightweight yet durable standing up to the rigors of range use training and outdoor conditions. This complete lower lets a builder pair it directly with a compatible upper receiver to finish a rifle quickly without sourcing a separate parts kit. For AR-15 owners looking for a ready-to-assemble quality forged lower the Sentry offers a straightforward path to a finished build.
