Pros
What a beast
Cons
None at the moment
This rifle is fun to shoot and would be an good option for air gun hunting. Mine has a very slow air leak. It doesn't effect performance, however if the rifle is left for more than a few days the air tank loses pressure.
Pros
Feels solid. Shoots well and seems accurate.
Cons
Typical Umarex quality control issues. Has a slow air leak.
HMMM...COULD THIS TAKE DOWN A GRIZZLY i have been hunting for 33yrs and i can actually say if the shot was well placed...U BETCHA!!!
Pros
well well well...totally impressed !!!!
first ,
I wanna say this is not a toy
if you wanna teach your kid how to hunt don't do it with this!!
one wrong move could kill you and him or her, so with that said ,
Overall,
I just love this gun it will give the real thing a good run for its money!!
when ever I go hunting this is my gun of choice.
Cons
Overall,
besides this being lethal in the wrong hands ..nothing bad to ever say about this gun.
absolutely love this.
I’m glad it did not fire I’ll try it up north at my dads place I’ll seat the magazine it should have no problem
Pros
Feel balanced
Cons
I went to fire it in the yard at 45 psi it would not fire I guess I have to line the magazine
I just don't get why people hate on the hammer. Ever since I bought mine it has been my favorite big bore...and I have several! I love my hammer and it even pushes higher velocities than advertised. I guess I just got a good one or something because I hear a lot of people hate on it! This is a tool, not a toy! Designed for hunting and it does that well. It surely will take anything in North America down so don't sleep on her....she is a beast!!!
Pros
Everything
Cons
Nothing
I’m thoroughly impressed with Umarex and thankful for Airgun depot !
Pros
Everything … The hammer is bonkers !
Cons
The air tank capacity without a tether is meh.
It is imperative that you use the correct diameter projectile. Yes, Umarex projectiles are way too expensive, but they are size-correct. It is possible to "bump" projectiles that are to small, using a small diameter punch tapped dead center in the nose of the projectile, resting on a hard surface. Caveat: you will have to mike every one to be sure you don't "bump" them to large.
Pros
Received my Hammer a bit over a week ago. Bad weather prevent any usage. Once things cleared a bit I sighted the rifle in at 60 yards using a Bushnell 3200 Elite scope, took four rounds, last two less than inch apart, using Umarex ammo. I also have a Seneca Dragon Claw and had a box of Air Venturi .50 cal 336 grain projectiles on hand. these projectiles dropped through the Hammer magazine with space all around them. Every projectile in the box miked at .48, WAY to small to be used. Umarex projectiles varied btwn .510 and .511. I read a review where the writer complained about air blowback from around the magazine, willing to bet he was using projectiles that were to small in diameter. I had been somewhat mystified when I could watch the projectile from the first round fired from the Dragon Claw, go down range. I miked the Dragon Claw barrel, .510. Simply put the Air Venturi .50 caliber projectiles aren't. This will drastically effect both velocity and accuracy.
Cons
Haven't found anything to complain about.........yet.
need advice on what to do
Pros
got my hammer hooked up the nomad 2 to it and it got to 1500 psi and wouldn't go any higher, due to leaks from the magazine are any suggestions on what to do ?????
Cons
need advice on what to do
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.
Pros
Took awhile to get one of these.got 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!
Cons
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.
Question?
Login to ask someone who bought this product.Do you Finance
asked John from USAYou can use Affirm, it is a third party loan company.
Adam from USACan I use a scuba tank to fill
asked Clifton from USAWhat is the total height of the hammer?
asked Matthew from USACan I take my hammer to a gun Smith to have the air tank replaced
asked Norman from USAHad anyone bought a suppressor for this rifle?
asked Stephen from USACan I use a scuba tank to fill?
asked Greg from USADoes 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.510 Bore Size
Brad from USAMuzzle tapped?
asked Tom from USACan you decock the hammer?
asked Terry from USAGiven 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 USACan you change the air tanks out to full ones like some other air guns
asked Steven from USACan you screw and unscrew the tanks to change them out to full tanks once empty
asked Steven from USANo
Brad from USADoes anyone make a bipod for this?
asked David from USAIf you buy a m-lock rail you can attach any bipod.
Steve from USAWill I be able to shoot this left-handed?
asked Frank from USAYes I am left handed and I shoot the hammer fine.
Steve from USAwill 50 cal hammer shoot air bolts
asked Carlton from USAThe 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 USACan nitrogen be used in place of compressed air?
asked David from USAIf 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 USAhow do you fill air tank? is it ready when shipped?
asked John from USAFor 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 USAYou need a compressed air source of 3000-4500 PSI. A hand pump .air tank or compressor.
Mark from USACan other commercially available bullets work in the Hammer such as a >50 caliber muzzleloader bullet?
asked Tom from USAMuzzle 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 USAAir 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 USACan you use a hand pump for this rifle
asked Lionel from USAFor 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 USAYes
Mark from USAWhen is my hammer being sent
asked John from USAHammer shipments are coming in small numbers. Backorders are shipped first.
Mark from USAHas AGD received and shipped any of these yet?
asked Tom from USAI 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 USAThe Hammer is being made in small numbers.We are shipping as we get small shipments. Back orders are being shipped first.
Mark from USAEl umarex hammer la gran mentira de umarex.es 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 USAEl 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 USACan 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 USANo. 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 USAIs 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 USAThere will be aftermarket suppressors available in the near future.
Mark from USAIs this capable of taking deer at 150 to 200 yards clean. All videos only show 50 yard shots.
asked Jeffery from USAOne of the guys at umarex said he has taken deer at 150 yards and a girl on YouTube has taken one at 140 yards.
Steve from USA
The recoil is between a .410 and a 20 guage shot gun , be careful when using scope
Pros
Its hard hitting and accurate , trigger pull is great , can punch a hole through1/8 steel plate at 35 yards using 440 grain hard cast bullets .
Cons
The bolt safety on stock is in a bad place , I shoot left hand so i remove it to shoot ,should have mounting for sling , would like more of a sport style stock, the only reason i gave it 4 stars was the stock saftey , that could hert a left hand shooter.
