Any one ever heard of the Dynamic PCP air rifle?

[Lastdog]

Yes Jason it groups very well but even maxing the scope can only get the group about 6 inches away from bulls eye.

Okay good, it’s not a bad barrel or clipping or something like that.

What about the air tube pulling the muzzle down via the barrel band when you put it in the stock?  If you can’t see something obvious, set up with some bags so you can shoot a group without the stock attached and see if that brings the POI up.

Another possibility is a bent barrel.  One that you can’t get on paper at a modest distance (under 50 yds) will be pretty obvious to the naked eye.  Unthread the shroud and sight down the outside of the barrel relative to the receiver.  It the barrel is banana-shaped or if it sags relative to the receiver, there’s the culprit.

Come to think of it, make sure first that the two grub screws securing the barrel into the receiver are good and snug.  If not, the barrel may be drooping.

Sounds like that’s what I’m going to do tomorrow. Thanks

These guns do have some very thick barrels on them too.  I'll be putting my DAR22 back together later today when the loctite on the trigger cures.  I'll also be replacing the internal -012 o ring in the reg with a 90duro.  I'll be leaving the regulator where it's at for now because it's got plenty of power the way it is.  I still need to get over to Menard's to find more appropriate hammer springs for these guns, I'm thinking I'll be able to find one size that will work for all of them because of such a short throw these guns have.  I also think that leaving the regulator on this gun where it's at will be good for the next mold that I'll be buying from NOE.  I'm sure that it'll be slinging the JSB18.13's into the 900fps category but I'm not going to use them on a chrony string because I don't have many left.

Wayne, if you do find a better hammer spring could you please post the information so I can get a couple. Would also be interested in a cone shaped valve spring. Thought I would build up a little back up parts bag for my dar 25. Sure would be nice to find some back up mags. I do have a 22 mag that I don’t need any more If someone needs it.

[nervoustrigger]

The hammer spring on the .25 is way too strong, at least for any power level fitting of its small plenum and middling barrel length.  To get reasonable efficiency in the 45-50fpe territory, I had to install one that was something like 0.4” shorter.   I just lucked out and had one in my assortment but I was just going to start shortening the original if not.

If you can’t get the velocity to drop by backing off the preload to where the cap is flush to the back of the receiver, it’s time to start cutting coils.

[Wayne52]

Jason I've never checked the wire diameter of any of the hammer springs in them but I'm willing to bet they're all the same.  That .4" is probably about how much of the spring protrudes before putting in the end cap.  I'm sure once I get a better spring in all of mine the efficiency will improve 100% after getting them all adjusted right.  You can see what I mean by that last chrony string I posted, way too much variation but the darned guns do shoot really good  but using too much air I think.  I'm still getting 30 good shots the way it is and that could probably be 35 good shots with a well adjusted hammer spring.

[Hoople]

This my be common knowledge, but someone commented that they didn't like the fact that DAR mags could not be topped off. They can; the first pellet in is the first pellet out. To top off follow the same procedure that you use when the mag is empty. Spin the face plate to first slot insert first pellet skirt first from the front, then fill empty slots from the back. Easy-peasy.

[Wayne52]

Charles the thing I like about the magazines on my SPAM16 is if I happen to have a pellet that's already chambered and ready to shoot I can insert the mag on an empty chamber.  Evanix and others have the same type mag, it's the higher end SPAmags that are like that.

[Hoople]

Wayne, I hadn't thought of that, it is a good feature. I got two extra mags for my Outlaw from SPA, man their parts inexpensive. I hope they to continue to sell them to us directly.

I am loving my two DARs. I think I enjoy the tinkering part about as much as the shooting part. My 22 is a laser, and after smoothing and polishing the trigger is pretty darn good. My 25 isn't as accurate (yet) as the 22 but it's getting close. The trigger is not as light either,  I suspect the hammer spring is heavier. When I get a chance  I am going to exchange them to test that theory. I haven't had any leaks in about 2 weeks from either.

Also I would like thank all of you guys for your great post and pictures on these guns. Sure has made working on them a whole lot easier.

[Wayne52]

Charles when I'm shooting the 26 grain pellets from my DAR25 at an average of 905fps the thing is extremely accurate, when I had it adjusted to shoot my 34.5 grain cast pellets for a 10 shot group it was very accurate as well, I think the length of the heavy cast pellets seem to be much more accurate in the 900's, I even noticed an improvement in accuracy going from the mid 800's up to 900fps with the long pellets.  The same goes with the .22.  If NOE doesn't get the 22 cal hunter mold soon I might just turn the regulator up on my .22 to get it shooting in the low 900's with the long 23 grainers as well, the way that it's adjusted right now it would probably shoot the 18.13 extremely well.

Here's a little update,

I spoke with the DAR rep today and asked for a conformation , (on if in fact), extra magazines were coming.
He assured me that he HAD in fact ordered them, (quite some time back), and they were supposed to be here by now.

 He was just as frustrated about it as anyone, and He clearly understands that several people want to buy extras when they do become available.
 
He will let me know as soon as they arrive, (He said we will be the first to know).
 I will update you all when that happens.

Thanks Ron

[Lastdog]

Thanks Ron for the update. I thought they had forgotten about us DAR owners. I will be watching. Would love to get two more 25 mags. Did they say anything about any other parts for the DARs?

[Rat Sniper (AKA: PaulT58)]

Thanks for the update Ron, we are lucky to have you as a spokesman, you keep us on the leading edge! 

[Wayne52]

Yes Ron thanks a lot for the update !!!

Well gentlemen, it looks like the DAR rifles have been an overall bust.
Aimsport has recalled all the unsold guns, as well as offering those who bought guns the option of keeping them or sending them back for a full refund.
Initially the guns were supposed to be recalled through Sportsman's Guide, but SG was pleading ignorant to that.
Aimsport had a talk with SG and worked out their issues and SG began taking back the guns.
They really don't have many recalls as only somewhere between 50 & 100 guns were sold.
I had 3 of them, in all calibers, with two not holding air right out of the box.
I decided that I didn't want the trouble that so many others were having, and opted to send mine back.
SG arranged for FEDEX to pick up my guns at my house, and I sent them back last week.
SG received them yesterday, and now I am waiting for a credit to show on my card, which will complete this deal that has been in progress since the first part of July.
It's a shame that the guns didn't hold up to expectations, as they seemed to be a great deal at the onslaught of sales.
It's just as well that I sent mine back, and I am very happy that Aimsport is a company that stood behind the sales.
I understand that the long awaited spare magazines that many owners wanted to buy will not be coming!
That's a real bummer, as what will you will do with your gun if your magazine should break, or you lose or misplace your mag? That will render your gun useless.

Bill, who told you there won't be any spare magazines available?  It's my understanding they are completely redoing these rifles and Version 2 should be released early next year.  Hopefully, they will use the same magazines and spares will eventually be available.  I'm looking forward to the next generation and plan on picking up one in .22 to complete my set!

[nervoustrigger]

Well I'm hanging onto mine.  It does ragged holes at 43 yards with all 3 .25 cal pellets on the shelf, and thus far no critter inside of 60 yards has walked away.

So they will get mine back when they pry it from my cold, dead hands.

[Rat Sniper (AKA: PaulT58)]

LOL!  I agree to a point, my biggest concern is lack of parts when something breaks. So far we have only had to worry about o-rings which are readily available. But what happens if, say your poppet fails?  Is this a standard size that may be available for another air gun???  If so, please let me know because I have one that leaking!!!!
