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!

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.

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.

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

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.

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.
