Diana Two-Sixty .177 Cal Air Rifle 22 Joule Gas Spring Break Barrel

The Diana Two-Sixty .177 caliber air rifle delivers consistent 22 joule power output through its advanced gas spring system, eliminating the maintenance requirements of traditional coil spring mechanisms. This break barrel design provides reliable single-shot accuracy for target shooting and small game hunting applications.

What Makes This Different

The gas spring technology replaces conventional coil springs with a sealed nitrogen-filled cylinder that maintains consistent compression force across temperature variations. This system reduces vibration by up to 40% compared to steel spring alternatives while providing faster lock time for improved accuracy. The sealed gas ram requires no lubrication and maintains performance consistency through thousands of shots without spring fatigue.

Key Features

• 22 joule muzzle energy output in .177 caliber for effective small game performance
• Gas spring powerplant eliminates spring maintenance and reduces recoil vibration
• Break barrel single-shot action with automatic safety engagement
• Rifled steel barrel with precision crown for consistent pellet alignment
• Adjustable two-stage trigger system with crisp break characteristics
• Monte Carlo hardwood stock with textured grip surfaces
• 11mm dovetail rail accepts standard airgun scope mounts

Field performance demonstrates consistent velocity spreads within 15 fps across 10-shot strings when using quality match pellets. The gas spring system maintains power output in temperatures from 20°F to 100°F without significant velocity variation. Target shooters report sub-inch groups at 25 yards with proper pellet selection, while the 22 joule energy level provides sufficient power for ethical small game harvesting at appropriate ranges.
