Dynamic .25 cal PCP - First Impressions and Observtions

[TleVta]

Gertrude let me try out his .25 last weekend. I was STACKING Benji Domes @ 25 yards.

IMO, if I owned one that had issues, I'd be sending it back and patiently waiting for the upgraded version.

[Gertrude]

I see that on Sportsmans Guide website they still have the 25's for sale

I just checked SG this morning, not only are they still for sale, the price went back up to $287.99!  They still don't have the magazines listed...

I have not heard back from Ed, so I have no idea at this point if he's going to offer an RMA or send me parts.  If he offers an RMA, I may just accept and wait for a Gen 2 model.  I guess I'll wait and see what he offers.

Paul,
It's a holiday weekend. Give Ed a call on Tuesday and I'm sure he will take care of you.
SG is to stop selling the rifles on Tuesday.

I was able to take the .25 on a short pesting session this morning.

I expected to see something other than a house fly that's some great shooting indeed.

Thanks Ron!  I hope he will send the parts, I don't really want to return the rifle and wait fo the next generation.  I'll get one in .22 when the next gen is released.  I already have some baffles and an adapter for a LDC coming foe the DAR25, so I'd prefer to just repair this one and keep it!

[nervoustrigger]

Wayne, thank you, sir!

Paul, will you remind me what part(s) you are needing?  Conical valve spring?

[Wayne52]

I never did check my 22 to see if it's got the conical spring but I know the 25 and 177 that I've got don't have the conical spring   On the 25 the last time I had it apart I did deburr the ends of the valve spring when it was apart, I haven't done that to either of the other ones.  I almost hate to even take them apart when they're all shooting good like they are but eventually I probably will because I do like to tinker with these guns.  I'm also thinking about sending my barrel end plug to David (Rocker1) to see if he might be able to make me an LDC like the one I have on the Prod for it, I have no doubt that will cut way down on the report for the .25.

Yes, I want to get a conical valve spring and the collar the shroud attaches to that sits next to the breech.  On the collar of my .25,  2 of the 3 screw holes are stripped and it just spins on the barrel.  If I could get these parts I wouldn't need to have it replaced, everything else is working fine.

Wayne, I sent David the dimensions of the baffles that go inside the shroud, he's going to see if he can make some with his design that will fit in the DAR25. I think they will quiet it down much better than the baffles that come in them.  I also have an LDC adapter coming from a buddy who make them, hopefully he was able to get it right with the dimensions I sent him. The combination of Rocker1 baffles in the shroud and a Rocker1 LDC attached to the shroud should make the .25 as quiet as the .177!   This is the reason I'm not wanting to return the .25, I have new parts coming for it and want to test them before I have to give up the rifle.

[Wayne52]

I've always wanted one of those mini lathes so I could make things like that collar you're talking about Paul.  I had a chance to buy a used small mill for $500 but turned it down last year.

[nervoustrigger]

Paul, okay did you manage to separate the collar from the barrel?  The way I’m picturing it based on “it just spins on the barrel” suggests the grub screws may have cut a trench in the barrel and the collar is trapped.

I might end up with a spare collar...thus my interest.

Yes, I did get it apart.  There were no trenches in the barrel from the grub screws rubbing.  All three were loose, but only one of them would actually tighten and hold.  But that one grub screw is not enough to actually hold the shroud secure and stop it from turning.

10-4.  I’ll stay in touch and if I end up with a spare, it’s yours.
 
If memory serves, the grub screws in that collar are M3 just like those in the barrel band.  It has a tiny 1.5mm hex recess which is not very forgiving at all…if the tolerances of either the screw or the wrench are off by just the slightest amount, the head will strip out so easily.  Worse still if you’re having to break threadlocker.  Mine were okay for now but if need be, I’ll replace them with ones that have a better formed hex recess or drill and tap for M4 grubs.
 
I went ahead and replaced the ones in the barrel band.  I noticed they were going in slightly under flush with the surface and I wanted to be sure there was 100% thread engagement with the full thickness of the band.  Aluminum is just too easy to strip out so I used some that were 2mm longer.  They stand proud from the surface slightly so I might file them slightly for a better look & feel.   I also added a 3rd screw at the 6 o’clock position.  The band is much more solidly secured to the fill assembly now.
 
Just wanted to share those details in case you want to incorporate any of it into yours to help avoid future issues.
 

[Wayne52]

Not complaining but I wonder how come they made the barrels on these so thick

[Gertrude]

Paul,
Let me see if I can help. I'll be talking to Aim Sports again very soon.

Wayne,
 I think it was an intentional design factor, so that the gun would not just "Float away",
 in the event that anyone filled it with Helium ?
 I dunno, .. just guessing here,     

[Wayne52]

Ron have you heard anymore news about what else Dynamic might be coming out with?

[Gertrude]

From what I understand, Yes, there will be more models coming in the future.
 I do not know the details on any of those yet...
 ..but I think there might be another model currently on "the drawing board".

 I know these current QC issues were quite an unexpected and unfortunate surprise to them.
 They are trying to do the right thing, step up to the plate, satisfy everyone in a reasonable manner, and correct these issues from repeating themselves. Naturally, they don't want to go through the same problems a second time around, when bringing a new product to market.

[Wayne52]

I'm glad they're going to keep pursuing these guns because they indeed have a lot of potential.

Thank you Jason!  Hopefully, Aim will come through for me and I'll get some new parts for the .25 and have it as nice as my .177!

Paul,

Thank you Ron!  I hope they decide to send parts, both are easy fixes that will get the .25 where it needs to be!
