Any one ever heard of the Dynamic PCP air rifle?

[Rat Sniper (AKA: PaulT58)]

Just my 2 cents, I have both o-ring kits from Harbor Freight and neither had an o-ring that really fit and held air in my DAR177.  I found them either too thick to where they would not properly seat into the groove, or too thin to where they fit but weren’t thick enough to provide a good seal.  I also have one of the kits from Amazon and there wasn’t really a perfect fit in that kit either, I was able to stretch a smaller diameter o-ring that was the proper thickness and get it seated into the grooves. So far it’s holding air just fine, but because it is stretched to fit, I’m not sure how long it will last. But fior now it’s working so I’m not going to mess with them till they start leaking.

I aired it up to 3000 psi Sunday afternoon after I finished some testing and I’m traveling this week, so it’s getting an endurance test while I’m away!  If anyone (Wayne) does figure out the correct size o-ring for these air rifles, please post the size here. I’ll definately be getting some spares to have on hand.

You guys get to cleaning your barrels, testing pellets and posting some 30, 40 or 50 yard groups. I'm squirming in my chair to hear if this is a thumbs up or thumbs down rifle. He, he.

Got to shoot my DAR22 late evening yesterday ( had been waiting on compressor oil). Tried to air up gun, nothing. Oh no! Then I remembered to cock the darn thing, aired right up. Went out to range and shot at 25 yards, got scope near zeroed. Moved out to 50 yards and fine tuned zero. I was shooting Crosman 14.3 grs. Figured I would shoot those for a while until regulator settled etc. Shot 20 shots total, the last 5 shots I shot for a group which was in a tight little cluster of what looked to be about 1/2" or a little less (ran out of light). Was going to shoot today but has rained all morning, hopefully I can shoot some this weekend.
You guys have a lot more experience with PCPs than me, but that said, so far I am impressed with my DAR to say the least. BTW, still holding air today.

[Hawkeye51]

Charlie, that sounds great! Thanks for the update. I hope some of the other guys have results that good. My first thought was about the Yong Heng compressor and various knock offs. Hard to beat the price, but you must be willing to do a little tinkering from time to time.

[Wayne52]

I did a boo boo, accidentally open the regulator up too far, the lock nut was loose when I opened it up and I took a wild guess where it should be set, well I was wrong

Geez this thing is capable of some power.  34.5 grain pellets

1.   937.5 = 67.34fpe
2.   934.6 = 66.93fpe
3.   898.7 = 61.88fpe
4.   882.3 = 59.64fpe
5.   866.5 = 57.53fpe
6.   857.1 = 56.29fpe
7.   851.8 = 55.59fpe
8.   841.2 = 54.22fpe
9.   812.0 = 50.52fpe
10. 808.8 = 50.12fpe

Wayne, are all your changes made to only the regulator setting or have you adjusted the hammer strike at all by turning the cover on the hammer spring?

Just a note on the H/F o rings. When looking at both the assortments (sae/met) the metric o rings don't appear to actually be truly metric size spec. What it looks like is they are the same sae's o rings and the metric assortment box gives the metric dimension of the sae orings. I only use them in a pinch, and sometimes for sizing. The best o rings are U.S. made mil spec. and tolerate co2 very well.

Mike, I agree. So far I feel like it's money well spent. The trigger needs some work, and my mag needs some TLC. Other than that I am a happy camper so far. Interested what Wane comes up with on the .25, might be one of those in my future too. Ha.

[Wayne52]

Tom I had turned the regulator up too far thinking it had changed with the loose jamb nut when I took it apart, now I've got it set too low, I decided to bag it for today and continue later on.  Since I turned the reg down it's too low now, it's about 660fps but the way it is now I could get a ton of shots but I was happy with 50fpe to begin with, I'll fool with it some more tomorrow probably.

Kaliforniaistan is now on the playing field with it's first DAR .25,
 The package arrived, opened box, cleaned barrel, pumped it up, set up the chrony, and ran JSB 25.39,
 Here's what it did straight out of the box.

[Wayne52]

Wow that's a nice string you got there, it's amazing you didn't have any hitch's like many of us have.  The darned o rings I got from ebay were wrong and I ain't gonna mess with mine anymore until I get the right ones (shipped today) from the o ring store. I sure used up my air from my 88cf tank fast working with mine trying to get it sealed right.  Today(actually yesterday) I brought both my tanks with me and got them filled on my way back from the state land (Terry lives right on the main drag out to the state land).

Here's Terry's compressor, I also showed him my cast pellets and slugs too.



I haven't checked my email but I did make an offer on one of the Chinese compressor's on the bay.
If I do get it I'll probably only use it to fill my guns direct.

Hey All,

I received the remainder of my refund from Sportman's Guide today.  I did get all my money back.

I'm glad to hear that the .25's are making good power. 

Thanks,

Taso

Nice string on day 1 right out da box.

[Gertrude]

My buddy just texted me saying it held air all night just fine.
 I will see him on Saturday and get to try the gun for myself.
Heck, with a factory string like this, I may have a hard time justifying a full teardown inspection.

So it wasn't falling apart out of the box, holds air and has a nice flat shot string.

Next you'll be telling us it has a beautiful select walnut stock.

Glad to hear some others are having good success with their DAR s. Mine is still holding air (since Monday), no problems. Hope to get some shooting-chroney work in Sunday, if not next week.

One thing that surprised me was how quiet the DAR .22 is. Noise wise it is comparable to my .22 Outlaw. It is not Marauder quiet, but pretty darn quiet  for just a hollow shroud imo. How loud is the DAR .25?

They are quiet, my .177 is quieter than my .22 Marauder!

Just met Ryan at the Aim Sports Office in Ontario, CA, good guy. Invited him to shoot with us this Saturday, he thought he might be able to make it out for some trigger time. They are working on other distribution outlets for Calif. and will have their website devoted to the DAR line of airguns up soon so we can order o-rings, extra magazines, fill-probes and other accessories and parts for the guns.
I’m happy with the .25 DAR I got. Did a shot string that impressed me that Ron “Gertrude” posted above. My plan was to tear it down and get a good look at it. But since it is holding air just fine, for now, I think I’ll just shoot it on paper at various distances and figure out the best pellets for it in its current “factory” state. So far, it seems pretty accurate. ONE *(&^ OF A GUN FOR THE MONEY!!!

PS. If you want one, you better order it quick from Sportsman’s because Ryan said they will be sold out soon. I just talked myself into ordering another .25. Oh,well...

Sportsman’s Guide has a $40 offcode for orders over $250 right now also, so that brings the price under $250!  Y

ou need to ask Ryan if they have a parts breakdown he can share with us so we can order parts.

I also would like to know if the TP is adjustable like on the Marauder?  I ask because there is a setbscrew located right in front of the trigger assembly and when I was reassembling mine after replacing the regulator o-Rings I wanted to ensure everything was good and tight, so I snugger everything down including that one. Well, once it was all back together and all aired up to 3000psi and I went to shoot, all I got was the click of the trigger and the slap of the hammer against the poppet valve. No air released!  Baffled, I removed the stock, remembered that little set screw was not all the way tightened down, so I loosened it a few turns. I put it back to tether and all work fine. In fact better than fine, before all the work to replace the o-rings CPUM 10.5 Pellets were shooting at an average 735 fps, afterwards they were shooting at an average of 903 fps, which leads me to think that may be an adjustment for the TP and I turned it open a bit further than where it was set from the factory. But, I would like to confirm this theory.

It would be nice if we could get an exploded view of this rifle in the near future.
