The Noveske Chainsaw 16" 5.56mm Rifle operates specifically as a direct impingement (DI) gas-operated semi-automatic rifle. Unlike piston-driven systems, this traditional AR-15 design funnels combustion gases directly from a port in the barrel, through a mid-length gas tube, and into the bolt carrier group to cycle the action. This direct impingement mechanism helps reduce moving mass, contributing to the platform's exceptional accuracy and lightweight handling characteristics. The rifle uses this gas pressure to unlock the rotating bolt, extract and eject the spent casing, and automatically chamber a fresh round with each pull of the trigger.
