The Umarex Hammer is with a caliber of .51" (12.97mm) at nearly 950 joule one of the most powerful airguns in production.
But raw power is not the only feature of the Hammer.
Lothar Walther barrel
The Hammer uses the high quality .51" caliber Lothar Walther barrels with a twist-rate of 1:24.
Combined with the built-in regulator, this gives the Hammer a high level of precision.
The high quality stock and its materials have been developed in cooperation with PolyOne
Combining this stock with a Magpul AR-style pistol grip gives a Hammer a comfortable hold.
Not featured on many big-bore airguns, is a built-in regulator.
The Hammer's regulator has a pressure setting of 207 bar.
This ensures 3 consistent full-power shots and only a power loss of 10% on the 4th shot.
The 22mm picatinny rails allows the mounting of scopes and red dots.
On the front of the grip are multiple M-Lok slots for mountings bi-pods, lasers, lights, etc.
The Hammer can be filled with a Foster quick-connect.
This is not included with the rifle and is featured in the related products if needed.
