German quality and loaded with features, the Hammerli 850 AirMagnum is so much fun to shoot that you'll have a hard time putting it down. This great combo comes with a MOUNTED 6x24 scope.

Let's start with the all-weather stock. You can take this gun anywhere and not worry about a fragile finish, because it's made from a durable polymer. It's ambidextrous, too, with a raised cheekpiece on both sides of the Monte Carlo stock! This CO2 rifle uses an 88-gram AirSource cartridge, giving you up to 200 shots before you have to change cartridges. Although the rifle comes with a scope, you can always remove it and use the installed fiber-optic sights. The checkering on the pistol grip and forearm will help you get a good grip while you plow shot after shot from this 8-shot repeater. This gun is everything you ever hoped for in a CO2 repeater!


We've recommended some pellets to help you get the most from this airgun. Check out the AMMO link. Remember to click on the ACCESSORIES link to get extra magazines, AirSource cartridges and other shooting gear.

Things I liked: On target right out of the box - feels balanced in the hand and trigger has nice pull. comes with two mags for loading pellets holding eight pellets each, at 10 meters will place those pellets in a nickle size or smaller space. Scope works well and has a clear site picture no fogginess. works well with RSW superdomes .22

Things I would have changed: Forearm grip has a little play do to the fact it covers the CO2 cylinder but is not noticeable when in use - price would go up to correct this minor flaw.

What others should know: Great for plinking do to the eight round Mag.

Things I liked: Great design and well made. Very accurate. I sighted it in for 90 feet and I may of gotten lucky but aimed high and picked off a squirrel 300 feet away. Without the scope the rear adjustable fiber optic ramp sight is nice and the front sight can be adjusted for windage. (I haven't had to touch the front sight yet.)

Things I would have changed: Better cover for the CO2 cartridge it kind of jiggles around, could have made it a more precision fit . Like to see it in wood rather than composite it might be heaver but would be really nice. I would by another if they ever make one in wood.

What others should know: All in all, it's a nice rifle.

Things I liked: Very impressive piece of engineering, excellent quality at a reasonable price. My combo came with the sight already mounted, and right out of the box it shot extremely accurately to 50 ft. Even with a steady crosswind the Walther sight could be adjusted well enough for this gun to hit cherry-size targets at 60 ft. The action is superb, very tight and reliable. I am thinking about buying the base model with open sights for competition shooting,

Things I would have changed: As others have noted, the hollow stock makes the gun too light. I solved this problem easily by squeezing a 10-oz tube of silicon into the stock. The gun now has just the right amount of heft.

What others should know: Extra magazines a must! Everyone I know, including the ladies, loves to shoot this piece. Regarding ammo, I have used all types and makes of pellets and have not found any significant difference between them. In the cold I can shoot one magazine accurately before the pressure drops.
