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!

The magazine release is weird and not very assuring along with the bolt safety in the stockWhat others should know:
.510 ammo, I bought "50" cal Seneca and it was to small, also it is very air hungry a good compressor and or a big tank is a must especially while sighting in your scope, also due to the barrel shroud a bore sight won't fit it
