DAR Gen II is now available

Any word on actual oring size for the reg? I replaced them with what I could sorce them locally still leaks out of the hole in the air tube.

I can measure my replacement set to get the sizes.  It may be the internal rings that are bad, did you replace both sets?

I replaced everything I could may be the one on the jet I dont think I could find that one local. I would greatly appreciate it if you did that.

For the all of a sudden poppet leaks after its been holding air fine....pay special attention to the brass insert in the valve.  The one the poppet stem rides in.

Polish the ID and take all the sharp edges off where the screw driver slot is. Then slightly chamfer where the poppet stem enters the insert.

I did as soon as i received my rifle upon inspection, because it had sharp edges and was rough if i applied any side pressure to the stem.

I have a feeling some are getting brass shavings from this on the sealing surface causing the problems.

I went through mine after receiving it, replaced a few orings that worked and had on hand and the above. Its been running like a watch for over 2500 pellets now.

Is that the teeny-tiny oring?

I've actually had a few very good days with the DAR in a row and they continued today. The poppet is holding 3000 psi just fine with no loss. I am also have good luck with accuracy too, at 50 yards, I hit 5 shots on steel right on top of each other, I did not measure the group but it cant be larger than 3/8"!

I also did very well at 100 yards with a breeze from the right. I am just shooting CPHP because they are cheap but am also delighted to find that the DAR really likes them and although the JSB's do stack a little better, they do not perform x3 times better which is what they cost.

I Don't know what that one was for?

But.... it works like a charm under the ball bearing under the degas screw.  Keeps you from having to gorilla tighten the screw.

The factory overtightened mine so much that the poppet seat is no longer removeable!

I didn't think it was? Figured it was a press fit.

I doubt it, it has to seal somehow.

Yes the one on the brass adjustor on the reg.

I know that is what I was thinking looking at the valve seat  today ,  light polish with 2000 grit paper sealed up to the poppet ,and I thought at first no more leaks then after a few hours pressure gauge went down , so now I have figured out the fill valve has a very slow leak coming out of the fill hole , so tomorrow I will mess with it and see if I can get it to seal up ..    I hope it acts like my DAR .25 soon ... sealed,  and shooting perfect ...    DAR-nit ..

Dan, do you have a pic of the seat out of the gun? I have an issue I would like to address but if it is a press-fit, I'm gonna let it ride!!

Also, what grain pellet does your .25 like?

Man I can not keep this gun from leaking !  now it is leaking out of the micro size hole in the air tube just up about 4 inches from where the valve screws in maybe that little hole is for the reg ?  does any one no which o ring to replace that involves this small pin hole leaking ? 

one thing I do not like at all is the valve design , and poppet sealing flat on the valve seat instead of having it with a slight wedge shape to seal with more contact area , I think I might just return this DAR .22 , and sell my .25 DAR that is working OK I am really not liking the design on areas of this gun .... and the air bleeder screw is also very hard to get to the seal the air off ..... so in 24 hours or so the valve poppet to seat has leaked... the air intake has leaked ,and now the pin hole is leaking where i guess the reg sits .....

never had this many leak problems on any gun I have owned in 20 years of shooting PCP's ...     I think it may be time to send the problem back to sender of such problems  ...


pellet wise JSB 25.39 shoot very well out of the .25 .... my NOE mold .25 pellets shoot really good also ...

[Firewalker]

Dan, yes, you have those o rings in your bag. They are the outside o rings on the reg, air is passing by one.

The reg is super easy to remove, just degas and remove the barrel and air tube, unscrew both caps and use a wooden dowel to push the reg out the poppet side.

When I had a slow leak from the vent on my Gen 1, it was the internal O-ring on the regulator piston.

I just got off the phone with joe I think it was at aim sports / DAR .. I have to send them the air tube back for the .22 unfortunately they won't return the  gun  for refund , but they will send me a repaired air tube .... so oooo I will wait till I get the new air tube then sell it after I test it , I also  have a bunch of .22 crosman hollow point 14.3 g that it shoots really good in this gun that can go with the gun if you like ,if you are interested  ...

My .25 DAR is now up for sale pm me if you want it , it holds air perfect , and works perfect , and very accurate .... 

[Firewalker]

Sorry to hear that, Dan.

Do any of you guys have a thread gauge?
I would like to know what the thread size is of the HS adjustment slug (cap or whatever you want to call it).
To make a better SSG with longer springs.
Thanks for any and all help.

Also have any of you measure the barrel port? I measured mine and it is already .171. Would you guys go any larger? I want a little more umph to get the Baracudas (21.14) to the 910fps range, currently the best is 868fps. I have already played with the springs, the reg is at 145bar. I have even wound me a .051 spring. I even used the spring out of the .25 DAR (.057). Any suggestions would be great.

I wonder if the poppet will allow enough air for you? You will also have to tap the hole you drill through if you enlarge the TP. I don't know it it will limit you if you open the barrel port.

I will measure the thread this weekend as I have some plans for the .22 version. Think Armalite furniture. 😁😉

port wise you want to go 75 to 80 percent of caliber bore size is the general rule to keep air velocity up ....

Well I did 2 more attempts at getting this reg to seal replaced all o rings ,and to no avail the darn thing is still leaking , maybe yank the reg out and jb weld that micro hole up and run the gun with out the stupid leaking reg that the right o rings  I guess are not available ?

 I used the extra ones the gun came with , it didn't work then I tried a larger small o ring and it didn't work I think it may have got damaged a bit but it did slow the leak down I think ..... that micro reg hole just wants to keep on leaking ...

I am getting to the point I want to take a sledge hammer to this leaker ,and put it out of it's misery ! ...  { it really deserves it at this point  }  no the air tube will be sent back to Aim Sports so maybe they can correct their mistakes , who knows ....


have any of you guys tried to run this gun with out the reg ? ....

Dan, that's really interesting since the regs outer body on mine was a solid tube, no holes at all for air to pass through so I have to wonder if the air chamber walls are scratched? What did you use to push the reg out?

If you want to go without the reg, just pull the inner piece out of the reg, the black outer portion should seal the weep hole.
