One of the world's most powerful production PCP hunting rifles has arrived'The Umarex Hammer. With a massive 700 fpe of knockdown energy and multi-shot capability, Umarex has changed airgun hunting forever. Made right here in the USA, the Hammer was conceived, designed, and engineering in America, built in Fort Smith Arkansas. Delivering two .50 cal. rounds one after the next, the Hammer uses the patent-pending Light speed Valve designed to provide consistent 3,000 psi of pressure behind each shot driven by its huge 4,500psi cylinder. This innovative system was built to sling a .50 caliber 550-grain lead slug at 760 feet per second and a 250-grain slug at over 1,000 feet per second. These factors add up to a big bore that can fire 2 fully-powered consistent shots, plus one more follow-up up shot. Once you fire your first shot, move on to the next by operating the straight-pull bolt to progress the 2-round spring-operated chamber magazine. The bolt's low 2-lb cocking effort makes taking a follow-up shot smooth and simple. For added protection to the shooter, and anything downrange of its .50 cal. barrel, is a 3 step safety system that includes a hammer-block, a magazine lockout that prevents the gun from being fired without the magazine inserted, and a manual trigger safety. These features are set into a rugged polymer stock developed in collaboration with PolyOne Corporation, renowned for their innovations in specialized polymer products. This collaboration resulted in rugged all-weather design that can take the abuse of long trips into the field, and even includes a rear sling stud for attaching your own sling, and three slots in the forearm for adding other M-LOK® accessories. Designed with the shooter in mind, the Hammer features a long 8.5" Weaver/Picatinny rail for zeroing in on your quarry. The Hammer's barrel is reported to be to put its first two shots within an inch at 50 yards and is fully-moderated to help keep the noise down. Each includes a standard Magpul AR grip that can be switched out for other AR grips. Umarex is once again at the forefront of airgun innovation with a rifle that is sure to dominate airgun hunter's arsenals for years to come. If you're ready to hit the trail with giant big bore shots, devastating take down power, and a rough-and-tumble design, unleash the Hammer and harness the energy of the most powerful production PCP air rifle in the world!

Buy one if you can,can't go wrong unless you get a reject. I'm not much on Umarex,but my air rifle was good.which is to be expected.Any company will mostly except returns and make it right,so don't hesitate,be patiently. Buy one! Fun,fun,fun. Little loud,not too bad in the open with not too many neighbors tho. Def not in town.use a range or a friend's country property.

Took awhile to get one of it last year from SG. Well packaged. Only came with 6 pieces of ammo, what a letdown on that. Nice an powerful. Tool long time to pump up first fill. Had to go over it tighten bolts. Looked to be in excellent condition receiving it tho. Shot 3 times, first shot went through 6" of wood different types, beffore gouging a large cup out of a cherry block! With the ammo. Had to order some and then I ordered a set of open picatinny sights online.looks tacticle! Nice powerful bad azz air rifle!

Should come mildly precharged,mine didn't. Needs moderator, needs more ammo with it for the price point and open sight or something. I guess they leave it up to the buyer for choice, I can understand.

By BradleyUSAJuly 16, 2021

I don't know why people hate on the hammer so much. I paid for mine out of pocket and have absolutely no complaints. This .50 Cal is a BEAST...regardless of what you may here by the negative comments from haters who probably don't even own one. I own many PCP's and this is one of my favorites!



By JohnJuly 6, 2021

I shot my Brother-in-laws. One shot drop on a 130lb wild pig at about 30 yards. I like the weight, which steadies the rifle in my hands. I don't like the noise for an air rifle. It's subsonic anyway and there are no restrictions in the US for a suppressor built into an air rifle. There is no reason that a large bore airgun isn't suppressed. If they suppress it, I'll buy one of my own. Otherwise I'll just borrow Jack's! The paintball industry regularly uses 4500psi tanks in 68cu-in and 88cu-in. A remote line to a back bottle with the proper valve would make fore a nice setup.

Power. Accuracy.

Needs a built-in suppressor. I'd like to see an option for a larger, off-gun tank.

By JohnJune 4, 2021


Needs 2 big things in my opinion. A suppressor. In the US, a built-in suppressor on an air rifle does not require a permit and the rifle is already sub-sonic. A provision for a remote air line to a back-bottle. 4500psi tanks are common in paintball (in larger capacities). It should be easy to do larger tanks and a remote line takes the bottle off the gun.

This would take take a bear. Ive shot 6 in my life, two shots is one more extra than you should need. Im basing this on what my 40 tradition does to pumpkins. Itll kill it no problem

Idk what people are talking about? This thing is scary fun! And I have not even mounted my scope yet! Just arrived today, took it out with some 550 hollowpoints. And blew the fuck out of pumpkins for an hour. Put 35 rounds through it. Freaking badass.

Fill takes 21 minutes 38 seconds. Timed it. But i get 8 shots. Worth the wait. Only thing id change is putting some normal sights on it stock. Theres nothing out of box, just the railing

By JordanMarch 31, 2021

Nice rifle seems to be of good quality maby the wait was worth it.

Recently purchased the umarex hammer from sportsman’s guide so far it has been a blast to shoot accurate and deadly power defiantly not a toy.

Would be nice if the mags seated better so you didn’t get the big blast off air to the face. And could defiantly speed up the production trim me over a yr to get one.

By KyleUSAFebruary 8, 2021

The guy below me is nothing but a internet troll. I highly doubt he owns a hammer. I don’t own one either but I’ve shot one several time and thought it was a very balanced and smooth gun. I didn’t have any complaints either did my buddy that owns it. I also have the gauntlet .25 and I absolutely love the gun great starter pcp equipment umarex makes!

Best looking 50 air gun hands down

Only one style of stock

By SteveUSAFebruary 1, 2021 Verified Purchase

Not sure why everyone is bashing the umarex hammer I have the hammer and there Gauntlet .25 and both arrived in perfect condition. Wish they had a nice .30 or a .357 in there line up..great air rifle glad I made the decision to get it.

Gun arrived 2 months early and works perfectly. Thank you airgun depot.

Only con i can find is what ammo to use with it.

By James USAJanuary 29, 2021

I bought my hammer from Umarex. I would have to state that the only other review on this site for this gun sounds like a competitor totally downing Umarex. Whats more to say? It is the highest powered PCP in production, made in America, and cost less than a $1000. Of course Umarex is going to have competition trying to knock it off the pedestal... It is sad when things come to slander

Great quality, awesome power

I would definitely like to have seen a high powered scope included for a more lethal combo.

By RayUSAJanuary 27, 2021 Verified Purchase

Get it cause it’s bad to the ass ! Crazy power

Power Speed And hits like a hammer ! Get one !

When I got it it was leaking air as I was filling it I cocked it and it stopped filled to 4500 was good to go no more leaking

Had anyone bought a suppressor for this rifle?

asked Stephen from USA

Can I use a scuba tank to fill?

asked Greg from USA

Does this Umarex hammer use .50 cal pellets or .51 cal pellets? I think its ridiculous to be limited to Umarex expensive ammo.

asked David from USA

Muzzle tapped?

asked Tom from USA

Can you decock the hammer?

asked Terry from USA

Given the 1:24 barrel twist what are the exact dimensions of the optimal bullet for the hammer? What molds have people used? Thanks.

asked Fake from USA

Can you change the air tanks out to full ones like some other air guns

asked Steven from USA

Can you screw and unscrew the tanks to change them out to full tanks once empty

asked Steven from USA

Does anyone make a bipod for this?

asked David from USA

If you buy a m-lock rail you can attach any bipod.

Steve from USA

Will I be able to shoot this left-handed?

asked Frank from USA

Yes I am left handed and I shoot the hammer fine.

Steve from USA

will 50 cal hammer shoot air bolts

asked Carlton from USA

The Hatsan piledriver and hammer are both .50 BMG not the .50 you are used to. Being that the airbolts are meant for standard .50 cal sizes (.492 to .498) i would doubt that it would seal well enough to fire an air bolt.

kyle from USA

Can nitrogen be used in place of compressed air?

asked David from USA

If your seals are good yes you can run N2. Just remember you will get more power but few shots since more N2 will be used then air every time you actuate the valve. Nitrogen is very nice because it is completely dry and will offer more power but you will inevitably get less shots.

kyle from USA

how do you fill air tank? is it ready when shipped?

asked John from USA

For the first fill a hand pump will NOT fill this gun. You will need compressor or air tank but after you can use a pump if you have time and Dedication

Steve from USA

You need a compressed air source of 3000-4500 PSI. A hand pump .air tank or compressor.

Mark from USA

Can other commercially available bullets work in the Hammer such as a >50 caliber muzzleloader bullet?

asked Tom from USA

Muzzle loader rounds will not be the right size. the hammer uses a .50 BMG sized round which is larger then standard. But yes you could use muzzle loader rounds if were lead and sized properly but they will be to small I believe.

kyle from USA

Air gun slugs are almost pure lead. Soft/ The alloy in muzzle loader slugs is much harder. We do not suggest using them in an airgun,

Mark from USA

Can you use a hand pump for this rifle

asked Lionel from USA

For the first fill a hand pump will NOT work until you get the gun taking air and up to 1000psi then if you have the time and a 4500psi pump then yes you can.

Steve from USA


Mark from USA

When is my hammer being sent

asked John from USA

Hammer shipments are coming in small numbers. Backorders are shipped first.

Mark from USA

Has AGD received and shipped any of these yet?

asked Tom from USA

I ordered one mid December and was told it would be shipped in march....was surprised when it came third week in January of this year 2021

Steve from USA

The Hammer is being made in small numbers.We are shipping as we get small shipments. Back orders are being shipped first.

Mark from USA

El umarex hammer la gran mentira de un fusil virtual.nunca a estado a la venta.yo e esperado para tenerlo por mas de 2 años y nunca a estado a la venta.solo se puede ver en youtube.lo exiben pero siempre posponen su fecha de lansamiento al mercado.que decilucion que mientan asi.pienso en realidad que el producto no sirvee o en realidad no existe y todo es un montage.umarex hammer .la gran mentira

asked Jose from USA

El martillo Umarex se est produciendo actualmente en pequeos lotes de produccin. Menos de 75 armas al mes. Actualmente estamos enviando todas las armas que tenemos para llenar pedidos pendientes. Una vez que se completen esos pedidos, podremos enviarlos a nuevos clientes. La pandemia de Covid-19 mantendr la produccin en niveles muy bajos en el futuro previsible.

Mark from USA

Can the Air Venturi Long Shotshells, #6 Shot rounds be shot out of the Umarex Hammer and is Umarex still producing the Hammer? How long is the wait on the Umarex Hammer?

asked Joseph from USA

No. the shotshells can only be shot out of a smoothbore. The plastic shell will gum up in a rifled barrel like the Hammer.

Mark from USA

Is suppression an option for this air rifle? And what is the maximum effective range for the .50 with use for game such as whitetail deer?

asked Markus from USA

There will be aftermarket suppressors available in the near future.

Mark from USA

Is this capable of taking deer at 150 to 200 yards clean. All videos only show 50 yard shots.

asked Jeffery from USA

One of the guys at umarex said he has taken deer at 150 yards and a girl on YouTube has taken one at 140 yards.
