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

The APF Armory Varmint 2.0 is a complete AR-15 upper receiver kit chambered in 6mm ARC, built around a 22-inch 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 in the PRS Lite configuration provides a full-length rigid platform for bipod attachments and accessories while keeping the build lightweight. The upper is finished in OD Green (ODG) and is precision-engineered for varmint hunting applications requiring extended-range accuracy.
