The Second Hand Firearm - Diana AR8 .22 Cal Air Rifle is a high-powered single-shot air rifle built around Diana's N-TEC gas-piston system and a conventional break-barrel action. Chambered in 5.5mm / .22 calibre, the AR8 combines a rifled steel barrel, adjustable two-stage T06 trigger, automatic safety and ergonomic synthetic stock in a full-size sporting air-rifle platform. Developed as a mechanically modern alternative to a traditional coil-spring air rifle, the N-TEC powerplant uses a sealed gas piston to provide the compression energy required for each shot.

The AR8 sits toward the more powerful end of Diana's break-barrel sporting range. Its design combines a substantial action with a long barrel and integrated cocking aid, while the stock geometry was influenced by modern European hunting-rifle ergonomics. The result is a technically sophisticated break-barrel rifle that retains straightforward single-shot operation while incorporating a gas-piston power system and Diana's well-regarded adjustable trigger architecture.

Diana AR8 .22 Cal Key Features

• 5.5mm / .22 Calibre: Chambered for .22 calibre air-rifle pellets, providing the larger-calibre option commonly offered within the AR8 range.
• N-TEC Gas-Piston Powerplant: The AR8 uses Diana's N-TEC gas-piston system rather than a conventional steel mainspring. A sealed gas cylinder provides the stored energy used to drive the piston during firing.
• Break-Barrel Action: Uses a traditional break-barrel layout in which the barrel assembly forms part of the cocking mechanism while also providing direct access to the breech for single-shot loading.
• Single-Shot Operation: The AR8 is designed as a single-shot air rifle, with one pellet loaded directly into the breech for each firing cycle.
• Rifled Steel Barrel: A rifled steel barrel provides the internal bore geometry required to stabilise compatible .22 calibre pellets.
• T06 Adjustable Trigger: Diana's T06 trigger is a two-stage adjustable system designed to provide a clearly defined first stage followed by a separate release stage.
• Automatic Safety: The safety automatically engages as part of the cocking cycle, providing an additional mechanical safety step before the rifle is fired.
• Rear-Mounted Safety: The safety control is positioned at the rear of the action, keeping it readily accessible while maintaining a clean trigger-guard layout.
• Gas-Piston Characteristics: The N-TEC system removes the conventional steel mainspring, eliminating spring torque and reducing some of the mechanical vibration associated with traditional spring-piston air rifles.
• High-Power Sporting Configuration: Published .22 calibre AR8 specifications place muzzle velocity in approximately the mid-900fps range depending on pellet type, test conditions and market specification.
• 11mm Dovetail Optic Rail: The receiver incorporates an 11mm dovetail interface for compatible air-rifle scope mounts.
• Adjustable Open Sights: Factory configurations use a front sight combined with an adjustable rear sight, allowing the rifle to be used without an optic.
• Ergonomic Synthetic Stock: The AR8 uses a modern synthetic hunting-style stock designed to provide a stable grip and consistent shoulder position.
• Ambidextrous Stock Geometry: The stock is designed to accommodate both right- and left-handed use, broadening the rifle's ergonomic versatility.
• Full-Size Air Rifle Platform: With an overall length of approximately 48 inches and weight around 8.5-9lb depending on specification, the AR8 is a substantial adult-sized sporting air rifle rather than a lightweight youth platform.
