Able to sling three regulated .50 caliber shots per fill, the Hammer utilizes Umarex’s patent-pending Lightspeed™ valve created specifically to deliver jaw-dropping power.  Crafted to throw 550 grain, .50 caliber slugs downrange at 760fps for an unheard of 700 FPE, and a 250gr slug at 1,000 fps—the Hammer has more than enough power to knock down even the largest game. Powered by a huge 4,500 psi carbon fiber cylinder that is regulated to 3,000 psi allows for 3 consistent, full-powered regulated shots with the ability for a powerful fourth follow-up shot.

Once you fire your first shot, move on to the next by operating the straight-pull bolt to index the 2-round magazine.  The bolt’s low 2-lb cocking effort makes taking a fast follow-up shot shockingly easy. Each Hammer includes two magazines to keep the shots coming.  For added protection, the Hammer employs a three-step safety system that includes a manual trigger safety, hammer-block, and a magazine lockout that prevents the gun from being fired without the magazine inserted.

The stock was crafted in collaboration with PolyOne Corp., renowned as experts in the field of specialized polymer products and resulted in a rough-and-ready all-weather stock built to support this rifle’s powerful shots.  Each stock includes a rear sling stud and three M-LOK  slots in the forearm for adding accessories.  The Magpul AR grip contours to the hand, and can be switched out for other AR grips.  When choosing your optics you will have a lot of options with the long 8.5” Weaver/Picatinny rail that rests right above its fully-moderated barrel.  This barrel is reported to be able to put its first three shots within an inch at 50 yards!

Things I liked: The Hammer is a few inches shorter than its competitors. This makes hunting in the brush a little easier. The two round magazine and the super easy bolt action make followup shots a breeze. With 350 grain slugs, the Hammer easily gets 1 inch groups at 50 yards without really trying. The power is there to take on most NA large game. Unfortunately Umarex changed their tune about being able to use sabots and only recommends full lead slugs. Trigger has a nice break and the balance of the entire air rifle is nice, albeit heavy. Included booklet is nice, with easy to follow instructions and photos. Air fill from a newer compressor takes 10 min to 3000 psi, another 10 for 4500 psi.

Things I would have changed: The Hammer is not ready for full production yet. The gauge, O-ring and inner valve is prone to air leakage. The hand guard is way too close to the carbon fiber bottle, so when you add m-lok accessories, they do not fit at all or scratch the air bottle. Ridiculous that it doesn't come with any sling swivels or even studs to mount a sling. The Hammer is heavy and would be undesirable for carrying on a long hunt without a sling. I would of preferred sling studs and swivels over the free t shirt and barrel sock they give you in the box. The field safety screw appears unneeded and its position is going to hinder left handed shooters. Fill valve and gauge would benefit being on the same side. The Hammer should come with the option of a small muffler as it is VERY loud.

What others should know: I've "owned" my Hammer since early February but have only had it in my possession for two weeks. There was a heavy air leak upon receipt. For the past 8 weeks, my Hammer has been back at Umarex repair for 6 of them. Umarex Customer Service is clueless about this item right now. When I phoned them for my issue, I was told everything from "to just dryfire it several times," to "remove the air bottle and examine it.." The later of course being the worse advice since you cant and are not supposed to do that. When I received my Hammer back, it was still leaking large amounts of air and had to be returned a second time. Very disappointing and troublesome boxing it all back up and driving yet again across town to a shipment store. I was eventually told by one of the designers that the Hammer appears to have issues with air leaking in 3 different places. An updated version to replace the current is very much needed. This would be a 5 star item without the quirks.

Things I liked: I haven't fired the gun yet! I do not have a scope or air compressor. It is really a nice rifle and fortunate to have one!

Things I would have changed: The manual needs to be bigger, for larger print to read. It's very difficult to read to help familiarize the rifle.

What others should know: Be ready to spend a lot of money for accessories for you to fire this rifle!

Things I liked: I like almost everything about this rifle it feels great, looks great, and it has some serious power

Things I would have changed: The only thing that I am a little worried about breaking is the magazine release it seems like it could possibly be a issue if you are not careful

What others should know: I am not sure if this is in the description or not but you will need slugs sized to .510 I ordered air venturi .50 slugs and they were too loose they slid right through the magazine so I decided not to use them
