Huma-Air Tuning Regulator For The Benjamin Marauder Airrifle


For the Benjamin Marauder airrifle we have designed a pressure regulator that can be used with the original pressure gauge assembly, but it is also possible to remove the pressure gauge and gauge assembly completely and replace it with the regulator body, so you have even more air volume available in the pressure tube!
It will give you a better shotcount and a full flat shotstring immediately.
This regulator is vented to the atmosphere without any modification to your pressure tube. So no drilling in the tube and also no creeping up in power, just slide it into the pressure tube following our fitting instructions.

For the real power lovers we have also a XXL volume plenum available to tune your rifle to the maximum power for extra heavy pellets.  You can select it by choosing the .30 model in the options

The benefits of the Huma-Air, Benjamin Marauder Airrifle tuning regulator are:

  • Higher accuracy of your rifle due to the elimination of the pelletspeed fluctuations
  • A constant pellet speed over the full working pressure range.
  • Maxiumum use of the air volume due to our ultra compact build.
  • It will give you a better shotcount and a full flat shotstring immediately.
  • Adding a regulator to your airrifle will probably give you the biggest benefit in the tuning process.
  • Often the rifle will make less noise due to better balance in air usage 


When you order your Huma-Air, Benjamin Marauder Airrifle tuning regulator you will receive:

  • Your regulator preset to your own wishes
  • A pressure scale in Bar’s on the regulator, for fine-tuning or re-adjustment
  • We will include a “Huma-Air regulated” breech sticker

This is the 2nd time I bought a Huma regulator for a Benjamin . Huma regulator is the best...easy to install and works perfect.


Good afternoon gentlemen, I have the pleasure and pleasure to tell you that the regulator works perfectly. I have it set in 145bar and I get 25 shots with a difference of 1 or 2 fps and in the 25 shots it varies 8fps.
I expected to have a higher count of shots but I think it is due to some air loss in some oring of the rifle. With respect to the regulator 100% recommendable I transform my marauder .25 into a beast of the presicion. 5 shots in 1/2 "to 50metros.Thcias an excellent product.

Bought this reg for my .25 marauder. Install is very straight forward and operates as promised. Installed set as received at 140bar and is so far pushing 25.4gr at 805 - 810fps but still playing with hammer Spring preload. But still, shots are showing to be reasonably consistent fps so far with 40-50 shots so far.
Very happy so far.

Great regulator. Shot a few hundred pellets first to break it in using .22CPHP. Once broken in it was able to double the shot count from 3 magazines with ave. just under 20fpe to 6 magazines ave. 22.5fpe, spread of less then 13fps and std. dev. of 3.4. It was actually less then SD of 3 and spread of 10 but a few on the seventh magazine was off the reg. Nice flat string instead of the bell curve without a regulator. Also got quieter too, all you hear is the hammer strike, spring and pellet hitting target. Also have a Hill valve kit with lite hammer and 4 O-ring (Bstaley) mod. Will try the SSG mod in the future.
