5. Trigger
The trigger of the Umarex 850 M2 is one of its better features. It is smooth and very consistent for firing 8 shots.

There is no sound suppression system, but pellets fired at 850 FPS in .177 caliber do not exceed the speed of sound. Hence, the noise that comes out is more grounded than the high pitch whistling that comes out of a PCP.

With all the equipment, 8lbs might not be the best weight for some, but the feel of the rifle is solid and functional.
The 850 M2 also comes with a clip-on cheek piece, which is very thoughtful and smart of the manufacturers. The piece is very handy especially when one needs to use a scope.
9. Maintenance
You will have to put the average amount of care that you do for any CO2 gun, but dealing with rifles that work on CO2 all have one problem. Carbon Dioxide can be hard to remove and in the 850 M2, it is even more difficult with the bipod attached. .
A downside of the gun is also its expensive 8-round magazines.
Most of them are priced starting at $30, which can be heavy on the pockets. If you want a gun for regular practice and shooting, getting this rifle may be a loss since it’s hard to maintain.
10. Accessories
The recommended accessories for the Umarex 850 M2 are the Umarex 88 g CO2 Cylinder and the Champion Heavy Duty Metal Trap. Although the latter is not necessarily needed, many reviews have explained how the CO2 cylinder is a game-changer.
With 88 g canisters, it can get around 45-65 shots, with 12 g canisters, it can get to about 25-35 shots. This makes the experience more fun as it allows you to shoot for a very long time.

Umarex 850 m2 vs Hammerli 850
The Hammerli 850 AirMagnum was a hit at its release as it was a fun-to-use CO2-powered rifle with great specs and a durable polymer finish. The rifle was a great weapon for shooting and getting frequent practice – which should be your priority when looking for an airgun.
It also featured a 2 stage trigger, rotary magazines, a good quality barrel, and fiber optic fixed sights. Overall, it made for a fun shooting experience which could also make it the best backyard plinker.
However, compared to the specifications of the Umarex 850 M2, the Hammerli 850 with a .177 caliber can only fire at a velocity of about 650 FPS and lets you fire up to 8 shots. This may make it the best plinking gun, but it is not much of a weapon for a hunt.
In this case, the Umarex 850 M2 is much more flexible as even with the same amount of rounds it offers, the velocity is that of 750 FPS on a .177 caliber, making it faster and more accurate. You can use it for target practice, small hunts, or plinking.

| Category | Umarex 850 M2 | Hammerli 850 AirMagnum |

| Shots Per Fill | 200 | 250 |
| Mechanism | CO2 | CO2 |
| Velocity | 750 FPS (.177 cal) | 650 FPS (.177 cal) |
