Benjamin Marauder Tuning Regulator


For the Benjamin Marauder we have a tuning regulator with a combined pressure gauge connection that can be pushed into the pressure tube. It will give your Benjamin Marauder a better shotcount and a full flat shotstring immediately. The pressure gauge can be screwed inside the regulator body and will indicate the regulated pressure.


The benefits of this Huma-Air Marauder tuning regulator are:


  • Higher accuracy of your Benjamin Marauder 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 one of our Huma-Air regulators for your Benjamin Marauder you will receive:

  • Your regulator preset on 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
  • Fitting instructions as pdf download

Pressure settings of the Benjamin Marauder Tuning Regulator

This regulator comes in the standart high pressure range (HP: 90-170 bar output)
Your Huma-Air Marauder Tuning Regulator comes preset on the most common pressure setting, or we will adjust it according to your personal wishes.
It is equipped with a clear pressure scale label, so you can very easy re-adjust, or fine tune the pressure setting without the need of a regulator pressure tester.

After fitting the regulator the rifle's pressure gauge will indicate the regulated pressure. You can ad our Benjamin Marauder Quickfill unit will pressure gauge and stainless steel quick connect fillprobe to see the reservoir fill pressure.

Excellent product.

Thane -

Solid and precise build quality. Regulation is even with no creep up in pressure. 32 shots in a row .25 cal @ 857 FPS and all within 1.5% velocity-incredible!

Jiří Stach -

All O.K.

Shipping to USA was much faster than I expected. For my Marauder air rifle .22cal installation is straightforward since documents are readily available from Huma-air web site. Regular was preset to 2000psi I got more than 40 consistent and accurate shots from 3000-2000psi. 5 shot grouping under a dime, 10-shot grouping usually under a penny (excluding 1 or 2 flyers somethimes) at 40 yards. It also came with a regulator rebuild kit

Works as advertised. Gen 1 Marauder .22. Set at 160bar, crono'd between 879-881fps for 14.3g pellets up to about 36 shots. I have about 200 shots on the reg so far. I forgot to open my valve set screw all the way so i expect a few more fps once i do. Harbor freight here in the states sells a really long flat screw driver for about $4. Makes adjusting regulator in place a snap. Grouping is way more predictable. Averaging .25 inch grouping @ 25yrds. Next purchase will be a better barrel.

Thank's Huma ..this is a very nice product!! it works very great and exactly in my Mrod cal.22
34 shots at 44 fpe.. That's it!!
I order the same for my Ev. Rainstorm!
Thanks for support

All I can say is WOW! My good old trusty Mrod has been resurrected from the very back of the cabinet and is back in rotation now! It was an easy install, workmanship is top notch, shipping was incredibly fast, and I went from refilling her after 2 full mags to keep es within 3% to 44 shots with jsb king 25gr at 845-850 fps for 40 fpe. In addition its now more quiet, much easier to cock than my war ssg, and it seems as if I shoot forever before refilling. This was my first regulated experience and will never go back. All of my guns will have regs before pesting season in a few months. All with HUMA regs!!!!

Tim (Shorty on GTA) -

Huma, you did it again. Great product.... Repeat customer for the new 25 cal Mrod with gauge port regulator.
40 shots at 40 FPE and 24 shots at 50 fpe with a spread hovering around 2% ES all on a stock air tube.

Frank W -

I got this in my .177 SynRod. I like how you can see the regulated air pressure. Easy to see when its time for refill. Works good, very stable FPS.

I bought the Marauder version. The machining and fit are excellent. It is very easy to install into a otherwise stock Marauder with no drilling of air tube required. Instead, you remove one o-ring from the gauge block (on the side toward the muzzle) and the regulator seals against that side of the gauge block with a supplied o-ring. The regulation is excellent. It does take up some of the airtube space since it is located on the high pressure side of the gauge block. I used it on my 177 Marauder. It has plenty of plenum space so it would work for higher power tunes.

Robert R -

I received my reg and it works as advertised. Thank You.

Tim (Shorty) -

Never thought I would install a regulator but, gave it a shot. 22 cal synrod with modded valve at .25" throat, .168" porting to barrel and custom short stiff hammer spring (dual wire spring).
93 shots on regulation and an additional 20 to 30 shots off regulation at 25 fpe.
3000psi to 1100 psi.
Thank you Huma air. This is as good as it gets.....
