For your *177, .22, or .25 Caliber Benjamin Marauder or Armada Rifle 

This is the best kit I offer.

Get the most out of your air rifle.
For lots of shots per fill with a low spread in pellet velocity. Better consistency, for the best accuracy.  
Quieter shooting, and more refined. 
+  No need to go through the hassle of sending your rifle off to a tuner.
+  Save money on labor and shipping charges by installing the parts yourself.
+  Also get the personal satisfaction of a job well done   🙂


The hill airgun parts are already precision machined, and are matched up for the best results. 
You can set the tune for the power level and shot count you prefer. For example; in .25 caliber and using a 3000 psi fill pressure, shoot 25.39 grain pellets at over  900 fps for about 25 shots (more power uses up the air supply faster), or shoot the 25.39 grain pellets at around 775 fps for around 65 shots (very quiet shooting tune), or tune for something in the middle (compromise between power and shot count).  40+ shots at around 842 feet per second with 25.39 grain pellets is a very popular tune.
Excellent choice for pellet Or slug shooters.


Includes easy to follow installation instructions.  Technical assistance is included with your kit. When installing your hill kit, if you have any questions just click on “Contact Tim” to send me a message.
+  Includes a drill bit to open up the air inlet port in your rifle’s barrel -only (.22 and .25 caliber). No need to open up the breech.
+ Now includes the hill airgun handheld deburring / reaming tool.  This tool is the Best option I have found to easily and effectively remove the sharp edge on the inside of the gauge port opening. To prevent air leaks, removing the sharp edge keeps the o-rings on the valve assembly and the gauge port from being nicked during their installation.
*For .177 caliber Rifles,  from about 14 foot pounds energy and up.  No drilling required with the .177 kit.  No need to open up the barrels air inlet port any larger, leave the port the stock size.  *The .177 kit is also an excellent choice for lower powered .22 caliber and .25 caliber rifles. Great for backyard shooters, pest control or for anyone that does not necessarily need higher power from their .22 or .25 rifle.  You will get a lot of shots per fill and will  fill the rifles air reservoir less often. Very quite shooting too.
