Wow! What a great gun. I recieved the gun today and I pulled the gun out of the box and screwed in a 88 g Umarex Co2 canister and fed 8 pellets in the magazine and started shooting at cans and plastic coke bottles at 10-20 yards. I was amazed that the gun was dead-on with the very good fiber optic sights that come on the rifle. I was popping the tops of the 20 ounce bottles at 15 yards with regularity withot making any adjustments to the sights. The gun was so fun to shoot with the fiber optic sights that I almost considered not putting on a scope. I did however eventually put on a UTG 3x9x32 Bug Buster scope. I was getting nickel sized groups at 25 yards very consistently with cheap pellets. I got around 200 shots before the accuracy started falling off as the co2 canister approached empty. I was very impressed with this gun and would highly reccomend it.

Not much to change on the rifle. it was bettert than I imagined. I would have liked it if Umarex had put a dab of pellet oil and a pellet sampler in the box.

The .22 caliber Umarex 850M2 is a high-quality, highly accurate, super-fun and very serious shooter, pest eliminator and small game hunter. I pretty much hate messing with CO2, but this one is absolutely worth the effort (my favorite over my CO2 Sheridan 2260MB, Crosman e1077w and Beeman QB-78s, as well as most of my other air rifles). The Umarex 850M2 is a mighty-fine shootin' iron!

Exceptional accuracy! I love using these open sights: they're my very favorite of the sights on the other eleven air rifles in my collection. The rear sight required very little adjustment to allow me to shoot with extraordinary accuracy. Fantastic shooting using a bipod or a front rest. The .22 caliber version is a very hard-hitter and isn't particularly pellet picky at all, although I've tended to shy away from pointed varieties: match, domed and hollowpoint pellets of different quality, weight and manufacturer all perform very well. The magazines do the job (so far -- I bought four, giving me five in all, but at half the cost of the rifle, the cost of those four plastic magazines was gosh-awful!). Good action on the bolt, allowing for some pretty fancy shooting when I'm in the groove. ;-)

The 8-round magazines are $30 bucks each no matter where you get them, which is ridiculously expensive! You'll need them, so get more than you can realistically afford. You'll use around 3-4 filled mags per 12gr cartridge. If you're used to going out w/lighter airguns, handling could be a bit awkward in the boonies; sturdy sling mounts would be a welcome addition. Basically, it handles like a real firearm, so many may prefer its heft. The CO2 cartridge cover can be a bear in use, but it has to be a tight fit to make the three rails useful (they are, but again, it makes removal and re-application of the cover even more awkward with just a bipod mounted, so I can't imagine how it would be with something on 2 or all 3 rails). The 'optional' 12 gr CO2 adapter is a must-have accessory. It shoots forever (~200 shots) w/88gr cannisters, gets about 45-65 shots w/two 12gr cannisters and provides around 25-35 shots w/one full and one empty 12gr cannister. The "adjustable" comb is a bad joke.

Maybe my best all-around shooter in a collection of twelve. CO2 system seems well designed and works well with large and small cannisters (with 12gr adapter), although the front CO2 cannister cover can be a bear to remove; it does need to fit well to make attachments useful (bipod/flash), but no laser on those front three rails. The .22 version is a pounder! Very accurate and hard-hitting. Should be devastating on small game, but I haven't tried it for the purpose.

(.22 version) Awesome. hard-hitting air rifle. Excellent build quality. The 12gr CO2 adapter is a wonderful and necessary accessory. Magazines are pretty robust. Accurate: excellent open/iron sights as delivered (needed hardly any adjustment) -- among my very favorite for acquiring target. Not pellet picky, but does best w/match, domed and hollow point types. Exceptional shot count w/large cannisters, very good count w/two 12gr containers, ~30 shots w/one full and one empty cartridge. It's a heavier air rifle but far from cumbersome. Love it!

CO2 cover can be tough to remove and becomes awkward w/bipod attached (get a quick-release adapter). Cheesy "adjustable" buttstock (I don't use it). Magazines are incredibly expensive (at least $30 each everywhere), but the more the better -- get more than you can afford, because it's great fun to shoot this rifle.

I put a bipod on it. Gotta love those picatinny rails. Love shooting this gun. Thinking seriously about picking up a Umarex Forge when they come out.

OK, since I can't edit my first review, I have to do a second. I have had this rifle for a few months now and continue to be impressed with it. I don't even like shooting it at 25 yards any more because it is just too easy. At 50 yards, two mil dots down it is dead on. At 100 yards I go 6 or 7 mil dots down. Am using the JSB Exact Jumbo 14.3 grain domes. I tried the Crosman Premier 14.3 grain hollow point domes and those (I am talking 50 yards here) tended to go high and to the right and I do mean consistently. They worked great at 25 yards, but I don't shoot that any more--unless the range I go to is full and I can't get on the 50 or 100 yard lanes. So, it's the JSB's on 50 and 100, and probably about any other pellet will work on lesser shots. Pic is of my target today--started on my 165th shot on a Umarex 88 gram CO2 cartridge in 80 degree weather. The high ones were a result of me actually aiming high on purpose. Everywhere but the bullseye! Target is 6 inches tall.

Like I mentioned previously, the plastic magazines scare me but are holding up so far. Spare magazines are brutally expensive, and for some reason shipping is expensive, too! One company charges 8 bucks to ship a single magazine. Its a freaking racket. Still waiting on the aluminum magazine to come out.

For 300 bucks it was well worth the money. Shoot it like you stole it!

Liked everything basically. I now have over 200 rounds put through it and haven't had a problem. Added a UTG4x32 scope and am hitting nickel sized groups at 25 yards consistently--using Crosman Premier domed hollow points--which was the only non-pointy .22 pellets Walmart had at the time. Ordered up some JSB Exact 14.3 gr domers as proscribed in some YouTube video. The gun came with a tin of Excite flatheads and they basically shot the same as the Crosmans. Gun also came with two 88 gram Sig Sauer CO2 tubes and I am still on the first on! We'll see how far past 200 it goes. Trigger is adjustable and good. Comes with a plastic, friction fit cheek riser which yeah, plastic, but seems to work okay. Bolt cycles smoothly. All in all I feel good about the purchase and am having loads of fun with the rifle.

2 plastic magazines came with the gun, and yeah, plastic? Not sure how long those will last but until they fail I won't complain too much. Replacement mags seem to be out of stock everywhere and are EXPENSIVE.

Will pointed pellets work with the magazine on this riffle? Pellets like the pointed Haendler & Natermann brass tipped ones? Thanks

asked Ron from USA

How does the action work; is it "load/insert the magazine, work the bolt, release the automatic safety and fire"?

asked Dennis from USA

Dose the Depot sale the Moderator or compensator

asked Bill from USA

What supressor do I need for this gun?

Mark from USA

Does this use the same magazines as the Hammerli 850?

asked Johm from USA

No. The magazines have been redesigned for the M2.

Mark from USA

Hi, I already own the Hammerli 850, which I purchased from you. Would you kindly explain which are the upgrades offered by the new, 850M2? Thanks!

asked Jose from USA

The gun is not different internally. The stock and muzzle have been altered.
