Building on the success of a long-time CO2 favorite, the Hammerli 850 AirMagnum, Umarex delivers the 850M2 with a handful of desirable upgrades. Maintaining the same high quality performance as its predecessor, users can expect tack diving accuracy, smooth operation and rugged reliability from this rifle.  

The 8-shot magazines in both .177 and .22 caliber cycle smoothly with the operation of the side bolt. This gun is made to shoot all day, and that is backed up by an impressive 200 shots per 88 gram CO2 cartridge! Take aim with the fiber optic sights, or mount a scope to the 11mm dovetail and see what this rifle can do. Additionally, the 850M2 features a 1/2" UNF threaded muzzle so you can add your favorite moderator or compensator.

The stock comes with a few upgrades over the original. The removable cover that keeps your CO2 cartridge hidden now features three picatinny rail sections for accessories.  These will come in handy for those that want to mount a bipod, lights and lasers.  There is also more texturing on the grip and fore-end of the stock to provide a firm and secure grip while you shoot  The ambidextrous stock also features a clip on raised cheek piece which will provide a firm cheek weld for scoped shooters. 

Whether you're looking to eliminate small game in the backyard, or drop tin cans with authority, the Umarex 850M2 is perfectly suited to handle all of your airgunning needs!

Things I liked:

This is the best CO2 pellet rifle I found so far and the bolt action is a big part of the fun. I had the Hammerli before and it is practically the same gun. However, the CO2 cover is more robust (not wobbling ) and the cheek piece has a removable raiser. I liked the new magazine. It is worthwhile to install a scope and explore the 50-yard range. The trigger can be adjusted and is light. The under rail may be useful if you want to have a bipod.

Things I would have changed:

Make the cheek piece adjustable. Replace the dovetail rail by a Picatinny one. I installed a scope 14.3-inch long, with 2.5-inch space to adjust each ring, and I had to use an offset ring set (UTG AIR 322S) to have the ocular in the right position for me (12-inch from the dovetail rails front). If the frame and the rear of the guns rail were 1-inch closer to the buttstock I could have used a regular ring.

What others should know:

If you are planning to explore the 50-yd plus range you may consider installing a 20 MOA raiser rail to avoid using most of the scope vertical range to zero it at 10 yards. Even with a 2.5-inch Sight Height the preliminary zero angle is 4.3 MOA at 10-yd, instead of 15.8 MOA without raiser rail. It is common having 0.25-inch group with JSB Exact Diablo Premium 8.44gr at 10 yards. All groups are less than 0.5-inch. H&N Sniper Medium 8.49gr has also a good result. The H&N Field Target Trophy 8.64gr and Match Green 5.25gr both jammed. The wadcutters spread a little more, RWS Meisterkugeln 8.2 & 7.0gr with H&N Finale Match 8.18 & 7.87gr were the best in this group. I use the Umarex 12 g CO2 adapter. To avoid losing power, put a little lube on the adapter (keeping it vertically) and install it with the guns barrel pointing down. Five magazines in a roll gave 40 good shots. The maximum with reasonable power is 56 shots.

Things I liked:

NOT built in China. Solid tight, smooth metal action. Decent trigger right there. Intuitive sights are light ,sturdy and bright. 2 tins later absolutely 0 troubles. Truly amazed that the Germans managed to build a rifle of this quality at this price point. Super Happy Backyard Hunter here. And no, nobody paid me for this review. Fast shipping. Thanks!

Things I would have changed:

Stock options . Gonna make my own American Black Walnut thumb hole stock.

Things I liked:

Very accurate a fine rifle.

Things I would have changed:

Better iron sights. Lower price.

What others should know:

Like I said it's a fine rifle but it does have flaws as least the one I received does. The CO2 cover latch release does not work I have to use a screwdriver to push it down. When I used the CO2 saver adapter the cover could not be closed all the way.When i removed the cartridge the saver stayed in the rifle and all the CO2 leaked out. I had to use needle nosed pliers to remove the saver. In spite of these things I like the rifle and enjoy shooting it.

  • andrew from USA asked:

    Has anyone used the Umarex 88 gram co2 saver with this gun and will the stock fit over it?

    • DocClary from USA asked:

      The Hammerli 850 was made in Germany. The barrels on the .22 and .177 versions of that airgun that I own are very accurate because of the fine craftsmanship. Where is this new Umarex airgun made?

      • John from USA asked:

        Does this use the same magazines as the Hammerli 850?
