The New .50 caliber Umarex Hammer is an Air Rifle!

Fort Smith, Arkansas (January 17th, 2018) – Umarex USA has officially announced the introduction of the Umarex Hammer, the American-made .50 caliber air rifle that has become the most powerful production airgun on the planet.
Umarex HammerThe Hammer has been conceived, designed and engineered in America and is being made in the U.S.A. Its assembly will take place in Fort Smith, Arkansas within the facility of Umarex USA. Adam Blalock, CEO of Umarex USA, Inc. said, “We continually look for products that we can make right here in the USA and more specifically, within the walls of our building in Fort Smith, Arkansas. The Hammer represents powerful innovation in air rifles and I couldn’t be more excited that we’re equipped to build it right here.”
The sheer energy and three full-power shots delivered by the .50 caliber Umarex Hammer is achieved by its proprietary, patent-pending, Lightspeedvalve. The innovative engineering used to design this internal mechanism coupled with a .50 caliber, 550 grain lead slug is responsible for the generation of its 705 foot pounds of energy at the muzzle. Almost as impressive, it only takes two pounds of effort to operate its straight-pull bolt. This short, effortless, two-inch action is all it takes to cock the rifle and advance the magazine.
Umarex USA’s engineers produced multiple prototypes of various mechanisms for the Hammer during nearly a two-year process that has resulted in the most innovative production big bore hunting air rifle. The soul of the Umarex Hammer is powered by our most essential element—air. 4,500 pounds per square inch of compressed air fill its on-board carbon fiber cylinder to a capacity of 24 cubic inches. The Hammer’s Lightspeed valve, coupled with a precision regulator instantly pulses a measure of air compressed to 3,000 psi, behind the projectile. This innovative patent-pending system efficiently propels a .50 caliber 550 grain lead slug at a muzzle velocity of 760 feet per second and a 250 grain slug at over 1,000 feet per second.
The Umarex Hammer has a multitude of useful and user-friendly features that both hunters and shooters appreciate. In addition to being the most powerful airgun delivering three regulated, full-power shots, it is the only production big bore air rifle that offers multiple shots from its patent-pending chamber magazine—other big bore air rifles require the insertion of a round into its chamber after every shot fired. Unique to the Hammer is the utilization of two safeties — a magazine lockout that prevents it from discharging without a magazine inserted, and a trigger block safety. “You won’t find safety mechanisms to this extent on any other big bores. The Umarex Hammer is the most powerful production air rifle in the world, so we charged our engineers, from the beginning, to incorporate safety mechanisms that would help prevent unintended discharges.” said Steve Lamboy, Senior Director of Strategic Development at Umarex USA.
Umarex USA collaborated with PolyOne Corporation, a premier provider of specialized polymer materials, services and solutions, in the design, engineering and material selection for the stock of the Umarex Hammerair rifle. As a result, the stock, forearm and other key polymer components are produced from Nymax, an advanced polymer that withstands the rugged trials of outdoor hunting and shooting. Designers from the IQ Design group at PolyOne added three locations into the rifle’s forearm that accept M-LOK accessories, and incorporated a sling stud into the lower half of the rear stock. Together, the advanced polymer materials and innovative design, including smooth edges and tight-fitting joints, form a modern and functional stock for the Hammer rifle that is both shooter-friendly and made to last. Richard Turner, President of Umarex USA, Inc, said, “In working with PolyOne, we targeted certain design and performance aspects of the polymer portions of the Hammer. The PolyOne team embraced our concept and the performance targets and worked hand-in-hand with our product development team to develop specific options that met our design, weight and most importantly performance goals.”
The Umarex Hammer is equipped with additional features that include a standard AR Magpul grip, Quick Disconnect Foster fitting to fill the onboard air cylinder, externally visible air pressure gauge, a button-rifled .50 caliber barrel, and 8.5-inches of Picatinny rail. MSRP $799.99.

Why would it be a publicity hoax? If they dont come out with the hammer i wouldnt buy any other airgun the only reason to buy the hammer is because of power!!
4/4/2019 9:32 AM
When will these be available??
4/11/2019 3:39 PM
I have been waiting since it was announced and last month allocated that money to another toy. It will cost more but look a lot better....check out some other folks like XP Airguns - its a wait but not this long.  Quackenbush might also be a good place - i didnt actually try them.  Umarex has obviously run into some issues.   Not to mention it probably sounds like a cannon and since they didnt thread the barrel you cant quiet it down.  If i want a loud gun I would purchase a firearm....and probably cheaper.
4/22/2019 11:43 AM
You are all idiots the hammer came out on the market in Lincoln April 2018 hot to pyramid air.com and search umarex hammer
5/1/2019 2:07 PM
I have lost all confidence in Umarex hammer and most Umarex products. doubt I will ever buy another  after you guys have promised this rifle for a very long time now
5/6/2019 4:46 PM
There is an error/inconsistency in your data for the 550-grain slug.  The table says 760 fps and 705 ft-lbs, but the "Features & Specifications" section says 790 fps and 760 (should be 762) ft-lbs.  Which data is correct?  Additionally, the Hammer webpage says 790 fps and 705 ft-lbs, which is just wrong.

By the time the hammer is available another company will have one comparable. I think I will wait simply because of the BS run around and lack of information on the delay.

Very bizarre! I have been seeing the Hammer commercial often on the hunting channels, and even showcased in some shows. Why is it not available yet? Government issue? Engineering issue? I think you've got a pretty solid customer base waiting...what's the deal?

7/8/2019 6:03 AM
What is going on with this rifle you plastered it all over the inter-net, but haven't made it available thus far. Sound like bad management and unreliable company.
8/20/2019 6:06 AM
When will you have product to sell
8/25/2019 4:35 PM
There is no way I would ever by this or any other product from this company.
10/19/2019 10:04 AM
I stupidly bought the Hammer from Pyramyd Air in August of 2018 and have been paying for it through their credit plan for over a year now. I contacted Pyramyd and asked about a refund of my money and all they offered was the return of the principal without returning any of the interest I have paid. I didn't mind waiting for a couple of months to get the Hammer because I thought it was a really cool concept and something I could use reliably to hunt with as I needed to. BUT, I now feel that both Umerax and Pyramyd have cheated me of both my time and my money. The very least they could do is to give us a reliable release date on the Hammer. I've about got to the point where I will never consider buying anything from Umerax (and I already have several of their guns) or Pyramyd again. I am just so sick of all the lies about proposed release dates!! Gene in Tennessee

Has the Hammer 50 cal o-ring issue in the breech been fixed and are you going to create a metal shroud that will be used to mount the scope?
7/28/2020 6:43 PM
Fake news and still a fake gun. I've sent email after email asking and asking about the hammer. They won't reply to any email that has to do with the hammer. They say its available so everyone goes and Pre-order's it ((stop Pre-order's or cancel your Pre-order's)) They are taking the pre-order sales to gauge the market on how much they should put into the production of the rifle WHICH IS ILLEGAL AND THE HAVE A CLASS ACTION LAWSUIT AGAINST THEM. THE ONLY HAMMER RIFLE YOU SEE IS IN THE HANDS OF INTERNET INFLUENCER'S AND ITS A PROTOTYPE.
7/28/2020 6:50 PM
If you goggle umarex Hammer issues there is a youtuber who takes the whole prototype apart and shows all the issues and problems with the rifle. For 1 the barrel wiggles so your shot placement will always be off. 2 The scope mount is held in place by plastic and two screws instead of metal. 3 it has o-ring issues inside the barrel which makes the gun unable to shoot. If you don't believe me just watch the youtube video. You can tell this rifle was just thrown together.
7/28/2020 7:01 PM
ALSO,! if you look through the videos of them talking about and showing the umarex Hammer at shot show in the past 3 years of them lying saying its available, so far after the 3 years the prototypes changed a bunch.  First it was a 3 shot magazine with a pump action reload then it went to a 3 shot magazine with bolt action reload then it went to a 2 shot magazine. So obviously they aren't finished with the rifle at all and i wouldn't hold my breath because either they are going to just scrap the production of the rifle because of whatever is holding them back or its going to take another year. If you want a powerful air rifle then THE HATSAN PILEDRIVER just made the hammer obsolete.  Hatsan piledriver .45 or .50 over 900fps with 700fpe just as powerful as this ghost hammer but you can buy TODAY!!

This all started when i was looking for a powerful air rifle that doesn't cost a fortune, that has the power to go elk hunting with out on the Oregon coast. I emailed umarex and the first couple emails went unanswered then i emailed them asking about nothing regarding the hammer and they responded within a day. So i knew something was fishy. So i looked up the director of marketing and sales (Justin Biddle) i emailed him saying i had a opportunity to market the new umarex Hammer for them with a never before seen (wild) elk hunt with a big bore air rifle. I said I'd film a complete review on the rifle with hunting clips and a full video of the elk take down. I know this would help get them free advertising and it would spark interest in a true business man.. WELL i was wrong because since the email was about the hammer .50, like all the rest i didn't get even a reply. Which makes this company very  unprofessional and i will put the word out to not support them.
