Sorry you're having so much problem, I have SN ...044, .22 cal., and have had zero problems, Holds air, very accurate and 30 shots at 880+ with 18 gr pellets. From what I'm hearing there may be more good ones than bad out there.

Here are the dimensions I got when I took it apart this afternoon to swap the Dura70 o-rings for Dura90's. The OD of the Regulator is .98", the ID of the Air Tube is 1.038". No to caveat that, I could only get the caliper in far enough to measure the ID of the threaded portion, and there is a slight step in from the threads to the section of the air tube where the regulator sits. So, the section where the regulator sits may have a 1" ID which would still give .02" clearance. It's hard to say for sure.

I did a very light honing with the brake hone. I sure didn't want to increase space between the regulator and the air tube any more, just smooth it a little.

I aired it back up and will let t sit for 24 hours to see of the Dura90's and honing helped. It has been losing between 10 and 20 Bar over a 24 hour period, so it should be easy to see if it's holding or not by tomorrow afternoon.

I'd say poor gunsmith work in that factory, if they do want to continue they'd better up their products.

Speaking of bad gun smithing: NEVER dry fire this rifle without air in the tube. The hammer face is concave, and will pinch closed the poppet valve shaft holder. The shaft will then stick. That holder will also back itself out. Lock-tite is apparently in short supply at the Dynamic assembly plant. Also, if your chronograph numbers start going wonky, take apart the regulator. After you get the piston and spring out, you'll find a slotted piston stem guide set screw (looks like an old school carb jet) and you'll probably find that it was not screwed all the way in. The more I dig into this rifle, the more I begin to have buyers remorse. But I have learned quite a bit about how NOT to build a regulated pcp. Whether or not Aim Sports comes up with a fix for my current issue, it's going back to SG tomorrow. Gonna order the MrodAir version of the Diana Outlaw (because of the extra magazine) the second I get a RMA from SG. I'm sick of this thing. Reminds me of my old Norton Commando. Ride for an hour, wrench for four.

I'm beyond disgusted at this point, no email again today. Sent a new email to Rich Neighbor at Aim who is the sales rep to Sportsmans Guide, told him of multiple emails between myself and Ryan and now no returns. Told him I will be home tomorrow if they want to talk to me in person, otherwise, want a shipping label sent and a refund of $319.99 for what I paid SG.

As far as leak testing goes, soap tested all potential areas and each time was at the vent hole for the regulator. Have tried multiple o-rings and all have failed to date. Now I'm done being the test dummy.

To TheSaint, good luck getting an RMA from SG as they will just refer you to Aim Sports just as they did me.

I’m a relative newb when it comes to PCP air guns, especially regulated ones. I have installed regulators in both my Marauders and neither one has a vent hole that I’m aware of. What is the purpose of this vent hole? Seems I had less trouble with mine holding air when that vent was plugged with a shred of rubber from the o-ring! It appears the air tube is machined the same on both ends, I.e. the offset from the threads. I know because I’ve assembled it backwards! If there were a way to plug that vent hole, would the rifle still function? Sorry if this is a dumb question!

tracker1955 · « **Reply #87 on:** August 07, 2018, 07:34:57 PM »

My understanding is regulated guns are vented to the atmosphere hence the vent hole. If a regulator were added to my synrod it would vent through the gage hole in tube, or vent hole would be drilled through tube if gage block and gage are kept.

Interesting... So, how does it vent through the gauge hole? Both mine still have the gauge firmly attached to the gauge block. They sealed and held air before the regulator was installed and in both applications the regulator just slid s in and sets next to the gauge block inside the air tube. I did remove one o-ring off the gauge block nearest the regulator as part of the install, but both held air just fine before and after the regulators were added so the structural seals essentially did not change from what it was before.

I noticed that one other guy got his barrel band replaced, mine was stripped out on the 25, I was going to tap it to bigger threads but if I can get them to send me a good one I'll be happy. Who should I contact about this

Yep, what Tom said! I contacted Ryan and had a new barrel band in about 3 days!

tracker1955 · « **Reply #92 on:** August 08, 2018, 12:05:02 AM »

PaulT58, as I understand it there are more than one choice of regulators for the mrod/synrod platform, some require removing the gage block, some work with the gage block but require removal of one o-ring, others work with gage block but require a hole drilled in the air tube. The removal of the o-ring is what allows it to vent to the atmosphere on the one you described.

On the DAR, it's there so you have an audible signal to let you know when the regulator o-rings have failed.

Mike if you do get the Airmax Dominitor I'm sure that you'll like it a lot. Mine is .22 and I have modified it a little since I bought it, I've now got it shooting the BBT 30 grains slugs like a laser@43fpe. The big difference when I bought mine was I had to wait for the tail end of the slow boat from China however the wait was well worth it. When you order something from Mrodair it will be at your doorstep in a matter of less than a week, he ships the stuff that he's already got in stock pronto with UPS.

This is the last pictorial shot string that I did with my Dominator, since then I've been into casting the 217-30-FN boat tail slugs, my Dominator is the main reason that I bought the mold because it's now got the power to sling them slugs nicely. I'm pretty much a hunter with air guns only however the slugs shoot just as accurate as any of the JSB's that I've fed it. I doubt you'll get the energy out of the 25 Dominator without doing modifications to it to get the 60+fpe that I'm getting from my DAR25 though and it's still basically just been tuned for what it's doing now without modifying anything except the better o rings.

Mike@mrodair even called me on the phone when I ordered mine, he said mine was the first one ordered so I was the original guinea pig for this gun anywhere, all the foreign distributors at the time hadn't actually gotten them yet so I was in the dark about the gun as well as Mike being in the dark himself. I don't know how many of these guns he has left but you just can't beat the price. I haven't talked with Mike since then but I've ordered several things since as well as the prior PP700SA(like the pistol a lot) I got from him. I hope that Diana hasn't clinched the market on these models like I've heard because the U.S. really needs a distributor here rather than being a third party through Diana.

I'm about at my wit's end! I replaced the Dura70 o-rings with Dura90 and it's still not holding air. The pictures below are from when I filled it at 4:30 P.M. yesterday afternoon till when I checked it at 6:40 A.M. this morning. I sent an e-mail to Ryan asking what next? The rifle isn't usable to me in this condition and I've pretty much run out of option, time and patience to continue troubleshooting this rifle without any compensation! LOL! I specifically asked if I should contact SG about returning it. It will be interesting to hear what he proposes as my next step. I really wanted to love this rifle, but I don't think it's quite ready for the mainstream market. If I end up returning it, I may try one of those refurb Hatsan FlashQE's in .177.

I am now curious to see who wins the Ryan sweepstakes and actually get a reply from him!!! To suddenly vanish as complaints mount is not good customer service.

tracker1955 · « **Reply #99 on:** August 08, 2018, 12:41:23 PM »

I did get a reply, will be contacting him by phone today to discuss my options, was also told they had server problems and that he didn't get my last email from Friday.
