DAR Gen II is now available

If you suspect the poppet to be leaking, strap a balloon over the muzzle and wait.

The actual barrel, not the shroud.

I just put the air tube in a clear glass of soapy water it works great , then just blow it dry with compressed air ... DAR really need's to come up with a high quality o ring replacement pack ...  I told Joe at DAR that is a must have if you are selling air guns  ...

[crazyhorse1]

if you have not heard of these yet, they are almost as valuable as a crony for PCP shooters.
 

Probably spend more time ultra sounding the rifle than shooting it...LOL

 Strange thing is my DAR .177 is solid as a Rock ... so far. Others recent experiences make me wonder 

[RDB]

The orings in mine must have been from the original run. Hard and flattened. Probably from setting in a hot warehouse. But found the problem ones and replaced them with what i had on hand.

The poppet leaked.  But was an easy fix. It seem to be a lot better material than the mush that other rifles in this price range have.

Its an easy fix if you have a stubborn one.  Just put a dab of jb bore paste or the likes. Id bet toothpaste would work. And just burnish it with a cordless drill.  It will true up the mating surfaces and seal up nicely with little effort.

Mines been solid after a little work.

 Yeah I have a couple of them mush poppet guns also, my .22 wood is doing just fine, I did make a Insta Morph poppet for my .177, and it is still working fine but I do suspect a regulator leak, as it will loose some air yet if it sits for a few weeks.
 Over all IMO the DAR is a better value vs the Nova Vista line. Seems if it has to hold air it will have issues no matter how much it cost.

Nice! The price is nice too!

That is what I thought about my DAR .22 and .25  ,,, they need complete tear downs and o ring replacement , and poppets seated better if needed ... probably have a good gun maybe after that .... my .25 is still holding air , but for how long is the question , if I end up keeping it I know I need to replace all the o rings , or it will wind up  flat tire/air tube  like the .22 did ....      and just think for mear pennies this could of all been prevented .. stupid little things like this can keep a gun ,and a bizz from being successful  ....

Shot this AM first string average of 750 FPS. Heat gun on spring plug got it out with the help of a modified watch case wrench, (used loctite on the threads) cleaned up the threads and went in .125” deep . Note: I did cut one coil off the striker spring two months ago. Now I am averaging 825 FPS with CPHP and grouping nicely. FPS is a little more erratic than I would like but a I’ll see if it will settle in before messing with the poppet or striker spring anymore.

[RDB]

Wrap the threads on the adjustment cap with dental floss. Works well for me.

[singleshotcajun]

With the time change I have just a little time to shoot when getting home while working long hours. Shot again last night . Still had the same amount of air from where I left it on Sunday. Twenty more shots, no time for the chrony but grouped well. I have emailed and called AIM several times in the last week with no reply to emails or messages. Is Joe still our contact or do we even have customer support anymore ? Just wanted to let Joe know not to send me a tank and to ask about getting some parts. Usually I refuse to be a Beta tester and this is why. I have plenty of old and obscure firearms that are difficult to impossible to source parts for but I knew that going in when I purchased them. Guess I can always make a poppet stem if needed.

How do I get to the poppet valve and regulator in DAR .25. Are they in the air tube? How to disassemble?

Yes but luckily, the air tube is easy to remove but you MUST degass the tube first.

[Fred E Krugar]

If you guys were to guess which huma regulator would fit our rifles.
 I think the ones that comes with the rifle is not very consistent.

I am also getting ready to order a couple barrels (.22 and .25) would you guys go poly or standard?

Almost forgot for the barrel i do want to be able to shoot slugs.

FWIW, the regulators in both my gen 1 and gen 2 work beautifully.  The gen 1 did exhibit some pressure creep after being left idle but so do the regulators in some $1000+ rifles.  Smoothing the valve seat took care of it.  I still haven't touched the regulator in the gen 2.

For example, this string from the gen 1 is a straight run of shots inside of a 2% ES until it begins falling off the regulator:

Jason, very nice  impressive data.

[Firewalker]

Nice shot string, Jason! Regretfully, I have to adjust mine, I get 14 shots before falling off with 25.2 gr WC.

How do I get to the poppet valve and regulator in DAR .25. Are they in the air tube? How to disassemble?

Yes but luckily, the air tube is easy to remove but you MUST degass the tube first.

I have the air tube removed, but how do I disassemble it?

I have the air tube removed, but how do I disassemble it?

Both ends just screw in but dont use the gauge to remove that end. I used mommas 'jar opener' tacky pad to get a grip and put the tube in a padded voice.

Keep track of what goes on which end, the tube looks the same from the outside once you have both ends off.

Once the ends are off, you remove the reg from the fill side by pushing a dowel down the tube and push out the reg and plenum out the valve end.

Take care to catch the plenum tube! Once out, the reg just pulls apart with the black and silver pieces being held together by o rings.

I have 2 different reg screws on my DARs, slotted on the .22 and hex on the .25. I have not spun either all the way in in fear of damaging the innards.

The poppet is in the valve end and is removed by turning the nut with four holes counterclockwise, there is a cone spring behind that. Count the turns so you can replace it the way it came out.

The poppet stem on mine looks to be titanium with a black delrin seal. The poppet seats on my DARs are both different, brass on my .22 and aluminum on my .25.

I did not remove the seats and I did not lube the stems in fear of fouling the seat. I cleaned them with alchohol and blew them dry.

I use a silicone gel for assembly and use "enough" to do the job. Once reassembled, I charge the tube with air. This way, I have the poppet stem at hand and can "bump" it or turn it to seat the poppet.

WARNING! Do not do this! I did so at my own risk and it worked like a charm but I do not recomend you do this!

I chucked up a very lightweight battery powered drill the the stem and turned it counterclockwise slowly until the poppet seated completely then topped off the tube, tapped the stem a couple times to ensure the poppet seated without leaking and then assembled the gun.

Regarding which end of the tube is which, there is a small vent hole in the side that is nearest the end where the valve and regulator are installed.

VERY small....
