When Aim Sports sent a new rifle to me I'd hoped I would be out of the woods, but I guess not. Went out today to do some chrony testing on the DAR 22, set my chrony up on the tripod, got my chair, Ipad and ammo, charged the rifle to 2900psi and got about three shots across the chrony when air began to leak out the breather hole in the shroud. I can only assume an o-ring let go on the regulator, rats. Pellet velocity was 851-854 and then hisssss. Contacted Rich and Ryan again by email and am waiting on a reply. My wife said to just send it back to them and get a refund, but I want to give them one more chance to make it right. Man they gotta do something about those o-rings. If I'd known these were gonna be such a problem I coulda just waited on the Fortitude from Crosman, seems now I'm waiting either way. $:-\$

I ordered AS568-117 B70 (NBR) Buna-N Nitrile 70 Duro O-Ring from the o ring store myself. I put 4 of them in the airtube and valve and my leaks disappeared.

Go down to your local hardware store and get some #117 Buna N Dura 70 o-rings. You'd be surprised at how easy these guns are to work on.

Regulator O-Ring Replacement:

1. Pull the stock (one hex head bolt)
2. Remove the barrel band (2 small set screws)
3. Unscrew the air tube from the breech
4. Unscrew the fill adapter/gauge from the air tube
5. Use a wood dowel to slide the regulator out of the air tube
6. Replace the two garbage o-rings on the regulator
7. Reassemble in reverse order
8. DONE!

Now, go enjoy shooting and don't worry about another air leak!

They have to be -117

I got mine from Amazon, a pack of 100 was a whopping $7.05 and they ship fast too! Or, PM me your address and I'll mail you some, I have plenty! I sure wouldn't send it back to Aim Sports, that just takes away from your shooting time!

Paul I got 46 of them left myself

I'm not sure I understand Wayne. You mean the #117's I got won't work?

These are the o-rings I purchased:

The ID is 13/16" and OD is 1" What size are the o-rings you got from the O-ring Store?

tracker1955 · « **Reply #8 on:** July 25, 2018, 03:19:24 PM »

I'm quite certain that with new o-rings I could fix it, just want Aim involved so they see and feel the issue. At the same time, I shouldn't have to buy o-rings for a new rifle that's under warranty. I would be willing to fix it myself if they spring for the o-rings, would cost them less than freight to and from Cal. again. I may order some from the o-ring store but will wait for their reply.

Same size, I seen those but I wanted to make sure the ones I got were the Buna-N's

They say they are "Buna Nitrile Rubber, 70 Durometer Hardness", I just assumed that meant Buna-N Dura 70! Hopefully they will work. Even if they only last a few months, I have a lifetime supply!

I remember when Mike@Mrodair went through the same thing with his early shipments from SPA, he called SPA to get them to install the better o rings. My Airmax Dominator has never need any o rings except for two little ones in the fill probe port, those are only a 20 minute job going real slow. Probe port o rings are the ones that take the most abuse.

Even the spare o rings I got with my Dar just split and cracked as soon as I tried them.

Wayne52 · « **Reply #12 on:** July 25, 2018, 03:29:23 PM »

Paul it looks like you got the same exact orings that I got just from Amazon instead of the O ring store.

Waiting not worthy, placed an order for some, thanks guys. Gotta love how this reinterprets what you really said. Oh well.

I wouldn't doubt that Gertrude brings the better o rings to their attention, he was supposed to be meeting one of them guys over the weekend I think. I'm sure that factory in China would probably start using the better o rings because that's very menial when it comes to the cost.

Paul when I looked up the measurements on line, the closest I could come to the size was -117 so I typed that in at the o ring store and there's for different kinds, the Buna-N was one that was on there and I went for it.

randy_68 · « **Reply #16 on:** July 25, 2018, 04:12:19 PM »

another option for orings like this are your local farm equipment dealers. I work for Case-IH and the 117 oring is number 238-5117 buna 70 or 277634 buna 90. they cost more but may be a quicker local option. I can cross a lot of std sizes over to 70 or 90 buna if you need them. just thought I would throw that out there

I wouldnt waist my compressed air on the orings that come in this rifle.. Reoring it right away out of the box and enjoy it.

LOL! True dat! Like Wayne, I tried the spare o-rings that came with the rifle and they were garbage also. I actually have 2 -116 o-rings on my regulator right now because I had those on hand and the -117's hadn't arrived yet. They are still holding air, so I'll leave them be till they start leaking than then I'll replacement with the -117's. No sense poking a sleeping bear!

Just read an email from Ryan at A.S. they are sending new o-rings to me, in addition to the ones I purchased earlier at the o-ring store. They are going to do a phone consultation with me when the rings arrive, I will do the work and my warranty won't be affected. I told them that if the ones they are sending are of the same quality as the ones already in there, that I'd prefer to use the ones I just ordered that have worked well for others with the same issue. We'll see what they say about that one when I hear back. Personally, I think they should recall any remaining stock from Sportsman Guide and replace all the o-rings in them before any more are shipped out. They know there is a problem with them, now is the time to get in front of it and prevent further issues.
