APF Armory Varmint 2.0 Complete Upper 6mm ARC 22" M-LOK PRS Lite FDE

The APF Armory Varmint 2.0 is a complete AR-15 upper receiver kit chambered in 6mm ARC, built around a 22" stainless steel barrel. The barrel features a 1:7.5 twist rate optimized for 6mm ARC projectiles, paired with a rifle-length gas system operating via direct impingement. A free-float M-LOK handguard provides a clean, lightweight platform for accessories along its full length. The upper is finished in a flat dark earth (FDE) Cerakote and is built to PRS Lite competition standards, delivering the precision and rigidity required for long-range varmint and target shooting applications.
