Personally I have had to call crosman for my Benjamin trail np. I sent it to them after they emailed the prepaid postage. They were very helpful and understanding. I only have the 22 cal so I can't speak for the other two cals. But for my gun I have been very pleased with it. Out to 100 to 110 yards a can has no chance. But this didn't come about over night. At first with CPs it was a tack driver. Then for some reason it didn't like them as much any more. It took going through a lot of different pellets and a lot of time on the chrony to find the right speed and tune. Just last week I had a head shoot on a squirrel at 61 yards and on one at 59 yards. Then a took a crow at 95 yards. I would say I have put somewhere around 2500 to 3000 pellets through the gun. If you want to trade it for a different caliber it depends on what you want to do with it. If you just want to shoot in the back yard I would go with 177. If you are going to hunt I would go with the 25.

Call Crosman and tell them your problem. They may try to help you fix it over the phone or tell you to send it back for repair. Be nice and they may pay return postage.

I remember I got very mad when my Crosman scuba yoke fill adaptor that I ordered from Crosman did not fit my scuba tank valve. I contacted them, but they simply said return it...no solution (i had to pay shipping) :lol: So insted of returning it I modified yoke by grinding off metal from under side of yoke to make it fit.

I guess I got lucky with mine as I shot it at 10 yards to begin with and put all the pellets into a tight little cloverleaf. It shoots great and the only issue thus far comes from that darn benjamin hand pump.

Here is a good video of a guy shooting his 22 cal. Marauder using Kodiak pellets @45 yards:

Putting the rifle up to my ear, I hear a bubbling sound at the breech. I had it up to 2000 pounds, and in the time it's taken me to type this it has decreased to 1600. Needless to say, I'm disappointed, but before I jump off a cliff I thought I'd ask if I've missed something and maybe experiencing operator error. Any help will be appreciated. Mike


Hi Mike, Sorry to hear of your trouble. I've heard that because the hand pump cannot deliver enough cfm (and psi) quick enough, the internal valve cannot seat/seal properly. Only the use of a high pressure air source (ie. SCBA or SCUBA) would correct this. However, two things you could try. Try backing off both the hammer spring preload (full CCW) and the hammer stroke (full CW) and try pumping up again. If that doesn't work pump it up as far as it will go then follow the degassing procedure, opening it up fairly far to allow significant air discharge (quickly), but release it before it completely empties. The idea here is to see if the valve will reseat properly. Hopefully, the first technique will work. Otherwise you may have to find a HPA source to initially fill the Mrod to 3000 psi. Good luck.

Sorry you are having problems. Quite a disappointment to think about getting the gun for a long time then get it and have difficulty once you get it. I had similar problems with my .22 mrod (marauder). The first was that the filling connector on the gun was mis-shaped and I had to machine it a bit to get it to connect to the hand pump. Next, I had a leak that would not quit, but it was different than yours. It seems that the mrod has to have a minimum pressure in the tank before some sort of safety valve closes. It may be hard or impossible to get up to this pressure with the hand pump for the first time. However, it seems that you would be way past that pressure as I believe pressure is somewhere around 100 psi. You might try and give it a few dry fires and see if this seats anything that might be leaking.

I discussed that problem on this forum here: viewtopic.php?f=17&t=1031

I am also having some accuracy problems and now a broken trigger here: viewtopic.php?f=30&t=1051

I am going to have to send mine back. Will have to think hard about whether or not I want to try the .22 again. I want to do some hunting and pest control so I would be asking for the .25, but .177 would be fine for just target shooting.

Best wishes.

I really appreciate the interest shown by several posts in reply to my query. I have been trying to contact Crossman, as I understand some have had good experiences with their customer service. I at least hoped to obtain a return authorization. I have called their phone number repeatedly, told told by the machine that they are open but no one available, so go to the on-line message procedure. Unfortunately there is a message that says "Contact Us

Maybe they are not taking any calls or messages during the holidays. In any event, I have a dandy brand new Mauauder with pump and an unopened box of Premier pellets if anyone is interested. I bought a chrony to help set it up, but think I'll keep the chrony. Thanks again for the sincere help and suggestions.

OK, so maybe I was a bit hasty. Of course they could have left a voice message saying they were not going to respond for the week, but heck, I've made worse mistakes. OK, a lot of them, but I digress. Today I picked up the rifle and again was surprised at how natural and nice it feels in my hands when I raise it. Looks like it would be just aweful, but it feels nice, and appears to be well made. See, I can say something nice. Getting to the point, someone suggested I dry fire it a few times and I did. Today I pumped it up again (100 pumps per thousand pounds does not quite get it). For grins, I got out the bathroom scale and found that the thing takes somewhere over 100 pound to compress the pump when you get over 2000. I got it to about 2100 and listened for the bubbles. Yep, a very, very little bit was audible. Two hours later I checked and it had dropped only about 100 pounds, so I pumped it up again. My back gave out at about 2500# and I quit. However, I don't hear any leak, and the pressure has stayed stable for a few hours now. Any ideas about this? I would have shot it but it go dark and I don't have a scope mounted yet. I bought a Simmons 3x9x40 AO, my first expeience with Simmons. I'll set up the chrony and get to work when family things it's a good idea :P probably two to three days. If it leaks more, I'll not shoot it and send it back. From all I hear and read ( a lot) I'd be happier with a 17 or 25, but I'm all ears to learn your opinions. I want best available accuracy, with minumum (other than normal set up and a few hours of tinkering) work to this rifle that is supposed to be sold as a good shooter. Sorry for so many words. Thanks a lot.

I hear the .25 is a air hog. If you do not like manually pumping, the .25 is the wrong choice. Maybe the .17 is the perfect choice if using just the hand pump because it uses less air.
