Gamo G-Magnum 1250 Air Rifle (Pellet) 4.5mm
The New G-Magnum 1250 by Gamo is our most powerful, accurate and ergonomically designed air rifle. Spurred on by the persistent market demand for increased power at an affordable price.
Gamo’s legacy began in Barcelona over half a century ago, when the company pioneered precision pellets for European shooters. From those humble origins, Gamo quickly evolved into a world-class air-gun manufacturer, setting exacting standards for performance, reliability, and value. Every part is crafted with meticulous attention—refined synthetic stocks, precision-machined barrels, and springs tested under real-world conditions—to deliver powerful accuracy shot after shot.
Introducing the Gamo G-Magnum 1250, the pinnacle of Gamo’s break-barrel lineup. Designed for shooters who demand serious power without breaking the bank, this rifle channels up to 36 joules of energy into each .177-caliber pellet. You’ll feel the punch of 1,542 fps on impact, whether you’re plinking cans in the backyard, zeroing in on steel plates at the range, or dispatching small game in your favorite hunting ground.
Ergonomics meet endurance in the G-Magnum 1250. Its ambidextrous “ERGOGAMO” thumbhole stock cradles your shoulder and guides your cheek naturally into perfect alignment. Textured grip panels and a raised cheekpiece ensure rock-steady aim, while the synthetic construction stands up to rain, mud, and temperature swings—no warping, no cracks, just unwavering reliability.
Beyond raw power, the G-Magnum 1250 shines in precision. A fully rifled steel barrel and spring-piston power plant combine for consistent muzzle velocities and pinpoint grouping. Each rifle undergoes rigorous in-line testing to ensure every trigger pull feels crisp and every shot lands exactly where you aim.
Balanced at just 3.0 kg (6.6 lb) and measuring a handy 121 cm (47.6 in), the G-Magnum 1250 offers nimble handling in the field. Cocking is smooth and predictable thanks to Gamo’s proven break-barrel design. Recoil is surprisingly mild, letting you stay on target for fast follow-up shots.
Whether you’re stepping up from an entry-level air rifle or looking to upgrade to a true European powerhouse, the Gamo G-Magnum 1250 delivers an unbeatable blend of power, precision, and comfort. Experience why shooters in over fifty countries trust Gamo to bring their best shot within reach—every time.
