Diana Twenty One 4.5mm Air Rifle
Unleash high-performance shooting in your own backyard with the Diana Twenty One 4.5 mm Air Rifle. Drawing on Diana’s 125-year legacy of precision engineering, this break-barrel marvel melds timeless craftsmanship with modern power. Whether you’re honing your aim on steel targets or enjoying relaxed plinking with friends, the Twenty One delivers consistent punch, pinpoint accuracy, and effortless comfort every time you pull the trigger. Its sleek, matte-black finish and classic lines turn heads on the range just as much as its performance wows at the target.
At the heart of the Twenty One sits a robust spring-piston powerplant that launches .177-caliber pellets at up to 1,000 fps. Each cocking cycle feels remarkably smooth, and the solid barrel lock-up creates a feedback-free loading experience so you stay focused on your shot, not the mechanics. The two-stage adjustable trigger—Diana’s Improved Trigger—lets you fine-tune pull weight for a crisp, predictable break. The result is rapid follow-up shots with repeatable precision and tighter groupings.
Comfort meets control in the ergonomic thumbhole stock, crafted from premium beechwood. Symmetric grooves guide your hands into an instant, natural hold—perfect for lefties and righties alike. The intuitive design promotes a steady cheek weld and solid purchase, while the cushy rubber butt pad absorbs recoil to keep you shooting longer without fatigue.
Locking onto the target is fast and intuitive thanks to fiber-optic sights that shine in any light. The hooded front sight captures ambient glow for a bright aiming dot, and the micrometer-adjustable rear sight offers surgical windage and elevation adjustments. If you prefer optics, simply clip a scope or red-dot onto the integrated 11 mm dovetail rail and you’re ready for long-range precision.
Built from high-grade steel with painstakingly machined internals, the break-barrel action locks up rock-solid shot after shot. The 16.5″ rifled barrel delivers flat trajectories and razor-sharp accuracy, while the balanced 42.7″ length and 6.4 lb weight provide stable handling without sacrificing agility. From the forged mainspring to the precision-ground internal surfaces, every element reflects Diana’s commitment to excellence and durability.
Whether you’re stepping into airgunning for the first time or adding a premium plinker to your collection, the Diana Twenty One 4.5 mm Air Rifle blends tradition, innovation, and unbeatable reliability into every shot. Step up your game with a rifle that’s as enjoyable to shoot as it is to own.
