The ATA Arms NEO inertia system uses recoil energy to cycle the action. Its primary operating components are limited to three parts: the bolt body, inertia spring and rotating bolt head.

The reduced number of moving components allows a fast operating cycle and simplifies maintenance. Unlike a gas-operated shotgun, the inertia system keeps combustion gases and most firing residue inside the barrel instead of directing them into the action.

The steel locking lugs of the rotating bolt head provide secure engagement between the bolt and barrel. The absence of a heavy under-barrel gas cylinder also contributes to the shotgun’s low weight and natural balance.

The included set contains five interchangeable chokes: F, IM, M, IC and SK. The different constrictions allow the shot pattern to be adapted according to distance, ammunition and type of hunting.

The selected choke must always be compatible with the ammunition being used. Before firing, make sure that the choke is installed correctly and tightened according to the manufacturer’s instructions.

The history of ATA Arms began with Celal Yollu, who produced his first shotgun in 1955 at only 13 years of age. Decades of experience and continuous development have established ATA Arms as an internationally recognised manufacturer of semi-automatic shotguns, over-and-under shotguns and bolt-action rifles.

The NEO series combines traditional hunting materials with modern CNC manufacturing, a simple inertia-operated action and practical adjustment and maintenance features.
