APF GUARDIAN .308 Win | 16″ Barrel | 15.5 M-LOK | 20RD

The APF Guardian is a purpose-built AR-style rifle chambered in .308 Win with a 16-inch phosphated 4150 CM barrel and a 15.5 M-LOK handguard. Its .750 carbine-length gas system and nitride BCG are configured for reliable cycling in a compact AR platform. This configuration suits medium-range precision shooting and field hunting for medium-to-large game.

Optic suggestion: a Vortex Viper PST Gen II 1-6×24 (or similar variable 1–6x optic under $1,000) pairs well with this platform for fast target acquisition and effective performance at typical .308 engagement distances.

Applications: medium-range precision shooting and field hunting (non-home-defense use).

Compact yet capable, the APF Guardian brings AR ergonomics to the .308 platform with components aimed at durability and reliable operation. The combination of a phosphated 4150 CM barrel, nitride-treated BCG, and a carbine-length gas system makes it a practical option for shooters who need a short-barrel .308 platform for field use or target work. The 15.5 M-LOK handguard allows accessory mounting without adding unnecessary bulk, and the M4 adjustable stock provides a familiar, adaptable cheek and length-of-pull setup. If you value a straightforward, mechanically-sound rifle built around common AR controls and parts compatibility, this configuration offers a balanced blend of usability and ruggedness.
