Any one ever heard of the Dynamic PCP air rifle?

[Wayne52]

So, this was the very 1st ever batch of them rifles right ?

Betcha they will get better and better as they get feedback,...looking pretty darn good as a starter.

As far as I know it's the first run, I didn't order mine til about a week after this thread started and mine is number 74, one member has number 2.

I had a chance to shoot mine a bit tonight after work, seems to like the JSB 18.13's and the H&N sniper magnum 18's the best so far. I had a tin of JSB Beasts that were a couple thousands to long for the magazine. I tried single loading a few but my power level isn't set high enough to shoot them well at this point. I also fixed the magazine so it would feed properly by drilling a new hole in the magazine back plate offset from the original so it would add a bit more spring tension. Prior to drilling the hole for the spring, it would only feed the first five shots before it quit rotating. Before drilling the new hole I tried adding a full rotation to the spring, but I think it was putting to much pressure on the mag when feeding a pellet into the breach, and may have been distorting the skirts. Haven't had a chance to run any across the chrony yet, maybe Wed. Tried lightening the trigger pull weight with the adjustment screw turned in per the manual but didn't feel like it was making much of a change. I might remove the action from the stock and see if I can get some lube down in there on the moving parts to free it up some. More to follow as I dig deeper into this thing.

with this thread already at 17 pages, I didn't want to derail it with a very longposting of this weekends shooting the DAR.25 cal.

 Here is a link to that thread
https://www.gatewaytoairguns.org/GTA/index.php?topic=146178.msg1486365#msg1486365

I will update as I gain more experience and trigger time with it.
BTW,
 We had a few of the regulars shooting this weekend who were so impressed with it's current performance and price point, that we went ahead and ordered FOUR MORE        of the DAR .25 cal, LOL ! ! !

I think you are right Manny.
When I spoke with Ryan at Aim Sports, He said that they are already working on a "Gen 1.5" to address the wobbly Cocking Lever issue, and He very much wants our Feedback if other issues or concerns arise.
 I got the feeling while talking to him, that Aim Sports actually DOES CARE about customers input, and if justifiable issues with quality or performance are present, they (Aim Sports) will make necessary changes to future models in the interest of improving design and QC.
I hope to be able to work closely with them, in any developmental improvements to the design.

Like others have stated. Have only two issues with my DAR. One, the mag is sticky. After 4-5 shots, shoot, cock, tap, shoot, cock, tap-tap. Second is the trigger pull, way... to hard. Gun is hard to shoot accurately because of horrendous trigger pull.

O-RINGS!!!  They definitely need to get some better quality o-rings!  BTW, for any YH Compressor owners out there, a blown YH burst disk makes a perfect shim for fixing that wobbly cocking lever!

[fivestar45]

Can someone take a minute to put a bare DAR on a scale?? I'm curious as to how much these actually weigh.
Thanks

Guy's..Does anyone that owns one of these rifles also own a scale, and has the time to weigh it.

Not sure how accurate this is, I weighed myself without the gun then weighed myself while holding the gun. The difference was 6.5 lbs.  This was without a scope or magazine, but it was filled with air!

Thanks Paul

I just went and did it, order another one in .177, I figured I needed a decent .177 pcp and SG had the $40 off for members so I joined as well, should have joined for the 25 cal, oh well I didn't know what I was getting into at the time but I do this time

[RBQChicken]

Wayne,
Don't you have a SPA .177 pcp? The one that's equivalent to the Diana Stormrider?  Or is that one I'm thinking of a .22? 

You must like the new Dynamic more than that one?

After tweaking my DAR177 a bit today, she's shooting 15gr H&N Sniper Magnums at an average of 859.38 FPS and producing an average of 24.60 FPE!  That's more energy than most of my .22's are producing!

The only .177 that I own that's a rifle is a break barrel, the Nitrovenom Crosman. My Airmax Varmint (PR900W) is .22.

I shot mine some more after work tonight, just can't get the groups to tighten up though. JSB 18.13, H&N Barracuda match 21.1 and H&N Sniper Magnum 18 are all shooting around an inch but are not clustering like they should, also looks like they may be spiraling a bit at 30 yards. I will run some strings over the chrony tomorrow and check the numbers, maybe they are running a little hot on FPS and the speed needs turned down a little. I just want to see at least 1/2" groups at 30 yards. I may try a tin of Crosman domes tomorrow as well as another member was having pretty good luck with them.

If you don't have any luck getting your groups to tighten up, check for clipping on all 5 baffles and the end cap. The system they use works great to quiet things down, but the tolerances can be a bit off. I wound up having to drill all of the baffles and end cap out slightly, and put an O-ring under the baffle hold down ring before I tightened the ring down and reinstalled the end cap. Presto. Problem solved.

Try a grouping with all the baffles removed to see if that improves accuracy. If so, its the baffle system

So did yours actually clip the baffles and end cap ?
Did it damage the baffles or cap ?
Did you take any pics ?

Dang it the -117's let loose throughout the night so this morning I ordered 10 in 90duro and one size up -118 in 70 & 90duro plus I got some 90 duro vitons coming as well, one of them should hold up good.

The -116's I put in mine are still hanging in there.  Have you taken it apart yet to see what happened? 

[Wayne52]

Yes I did and the o rings look fine, they just let the air go by it looks like, I even tried shimming them like the China factory did but they leaked right away then.  I ain't going to mess with it anymore until I get the o rings and the same goes for the .177 that's coming tomorrow as well.  Filling a 300cc tank from empty uses all my air up fast, I even got another one filled on my way back from the state land today.  13cubic inch's equates to less than 300cc's and I've pumped a 13 cubic in bottle before and it takes about 300 pumps to fill one with a hand pump.

Don't really think you can shoot this without the baffles in place. They're a compression fit, and appear to be integral to barrel alignment in the shroud. Somebody posted pics of the baffle assemblies out, and the fixture that holds the barrel somewhat on center in the shroud. That fixture is a slip fit, and without the baffels in place, you'll probably wind up shooting the end cap off. That's why there is a threaded keeper under the end cap. It, for lack of a better word, squeezes everything in the correct position.

I don't take pictures because I'm pretty computer illiterate. I've read the tutorial, but still can't figure out how to post them. I really want to figure this out because this gun is infinitely adjustable in every way from the regulator to the poppet valve tention. The trigger is simplicity itself, with only two moving parts and two springs. I've modded my trigger to where it breaks at exactly the same point, at just over a pound. The trick is to reduce the contact area of the pin that comes out of the hammer that engages the sear. Very similar to the mod that folks do to the Varmint/Stormrider.

As to the O-ring, I'm using 2.5X20 75 Shore A Viton's from McMaster Carr. There a post early on in this thread with the part number.

I've been in and out of ever part of this rifle over a dozen times, tweaking this and that. The o-rings have never failed. I lightly lube them with pure silicone 30w shock oil. I intentionally pumped mine up to 3800psi, just to see what would give. It held that for 3 days before I shot it down. I do own a compressor. Generic no-name. Fills the gun from 0 to 3000psi in under a minute and a half. Best 197.00 I ever spent on eBay.

Mike, that fixture holds the baffles in place, it screws into the inside of the shroud after you insert the baffles and before you screw on the end cap. To shoot it without the baffles, I would remove all 5 baffles, the retainers g plug (fixture) and end cap, then shoot it and see how it groups.

I have ont had he shroud completely off, but not for lack of trying. I removed the 3 set screws near the breech, but it just spins. I suspect it unscrews, but I wasn’t able to get t to budge.
