Bought a camo Chaser a few weeks ago after watching a local shooter's YouTube channel about budget shooting in South Africa.
We do not have access to the many aftermarket accessories and parts fellow shooters in the US have, so often have to just make a plan.
So far all I have done after adding a cheap and cheerful scope (will be replaced with something better later since the current scope does not have parallax focus).
- Polish the sear and hammer
- Adjust the trigger
- Change the internals of the silencer a bit which improves it.
- Shoot it quite a lot, testing in standard mode as well as with a spacer under the hammer spring.
A bit more tinkering this morning... really enjoying the little rifle, fun to shoot, fun to tinker with, not a lot of money down the drain if I do stuff something up.
One thing the CP2 has too much of is hammer bounce which is clearly audible when firing without a CO2 capsule installed.
Installed a simple MacGyver to stop that, this includes a spacer which increases hammer spring load as well - no more hammer bounce, the spring stops about 1mm before the hammer hits the valve stem.
(I will soon be making a new plug/guide for the hammer spring which will incorporate a guide, debounce and possibly hammer spring adjustment as well)
(https://live.staticflickr.com/65535/52006550190_94e1983dd1_b.jpg)
Shot a group to test.
Before the change, 100% standard, I would get 46 good shots at 10m but on the last 5 or so shots one could hear the hits are softer and the flight time is longer.
With just the spacer installed I would get 28 good shots at 10m and of course an increase in power.
With the spacer and my debounce MacGyver I get 40 good shots at increased power, then it drops off very quickly as can be seen in the 41 shot string in the photo - and no hammer bounce.
Quite happy with that - I am sure it will look a bit different at 25m with only around 35 good shots before POI drops, but I am OK with that as well.
(lower group in the photo is with some Umarex pellets I had lying around since lockdown, to date I have not owned a rifle which likes those)

Sadly I cannot chronograph at the moment, my chronograph attacked me last year while I was testing loads in my .416 Rigby, luckily I managed to stop it with a well placed 400gr monolithic hollow point...
Will get a new chronograph in the near future so I can test and tune properly.
I also notice the barrel crown is a bot rough, that will be tackled during the long weekend as well.
Just a shot of the backstop I used to show the hits on something hard...

Nice SSG! I like the way that looks, nylon string? Look for spectra line for longer life.

It is line I use for cave diving so pretty strong and does not stretch, and I have lots of it ;D
Had a look now and this looks like it could be 2mm spectra line or very similar.

Perfect!
You could sell a bunch of those to us that don't want to make one ourselves. A company was selling them for a while but had issues with short life of the string.

Too much fiddling required to get the string length just right while compressing the spring ;D
Had a look at the long SSG thread on the forum, will probably make a new metal end-cap with an internal all metal SSG at some point - when the string version stops working, want to see how long it lasts.

As I mentioned, the crown was a bit rough.
Cleaned it up with the Dremel and polished it using polishing paste and a brass bolt earlier today.
Cleaned the barrel, put a few fouling shots through while sighting, then took it out to 20m - I am quite happy with the results and the fact that it likes the Gamo pellets.
Think I will order a few 1000 of the Gamo Pro Match, will work well for plinking and close range pest control.
Square blocks on the target are 1/4".

That would make for 2 customers so far as I would too! ;D

To me it is an experiment.
Since I doubt the durability of the line, I would be hesitant to sell something like that to anyone.
And being on the other side of the world from the US, shipping would make it a rather expensive piece of string as well.

I am a big fan of Diana Chasers. I bought 2 of them. I converted the other one into a carbine and installed an aftermarket LDC from eBay. Planning to swap out the cheapo Diana 4X20 scope into a much better one. Just waiting for the dovetail-to-picatinny rail adapter.
I also swapped the native screw at the butt of the grip that has the rifle sling hole with just a simple flathead screw because I like to cup the grip with my other hand and the native one is just too big.
If you want to get better suppression, play around with the internal baffles. I switched the first one and inserted it the other way around and the report was lessened compared to the original configuration.
These things are so accurate. The red laser on the pistol is a dead shot at 40-50 feet.

Well... yes. I do make a lot of parts for other hobbies as well but I don't WANT to make another SSD, I'd rather buy one. I have the Chaser shooting 750 FPS for 10 shots off the SafPack with a single O-ring BStaley mod. No bounce so Im OK for now. 8)

I’d buy both…

Are you using the OEM hammer spring or you sourced a different one..you got specs/measurements😁

I am using the OEM hammer and spring with a single O-ring, BStaley mod and it's working great! I will get those light weight hammers done though, I really want to see what they do.

I think you said in an email it was M14x1.5, is that correct?

Just ordered 25 in Buna 70 and 25 in Buna 90 to see which one works better.

I don’t make hdd’s and sell cause of liability reasons. Say I make one someone installs it in their gun shoots the neighbor’s neighbor. Opppps here comes a lawsuit lol no thanks.

After shipping delays because of a number of public holidays the 2-7x32 AO finally arrived this morning, replacing the super cheap 3-9x40 non-AO I had on it.
Am thinking I will be able to use lower mounts with this scope but just mounted it on these mounts for now.

My .22 Diana Chaser rifle arrived a few days ago. So far I am VERY impressed for the price. Seems accurate with all pellets, even Crosman Pemieres. With the long barrel and silencer, whisper quiet. This is gonna be a great backyard pinker. Better trigger than the Quattro on my Hatsan, and that’s a compliment.
I may eventually drop one of my spare scopes on it, but for now just running a 30mm red dot if I decide to go back to pistol configuration.
The little tool that threads in the front cap is genius. Anyone else would just include a separate tool to carry around.

You can also put a spare CO2 cart in the grip.

Yes, forgot to mention that, and the fact it came with a pack of replacement seals as well.
While the carrying case is a nice touch, it’s kinda useless except for storage cause once you mount the stock, the long barrel or can, it won’t fit. The existing foam could be cut for the stock/pistol only but while the stock does come off easily, I wouldn’t want to repeatedly swap barrels and lose a gasket or screw. I have a block of solid foam I can cut down so I can repurpose the case but I’ll just be using a std. rifle case for the Chaser.
I have some mags on their way from Croatia so for now I’m in single shot mode, so can’t comment on how the left side bolt will work with ‘rapid fire’ but it’s perfect for single shot mode.

The Croatian CARM mags are very nice and worth the wait!

Been a bit busy with work and other stuff, but eventually got to drawing up and making an adjustable cheek piece for the little rifle.
It is based on Bob Pattenden's design, which I would have gladly purchased but he does not ship to South Africa, exchange rates not so good for us at the moment, and I have a 3D printer.
Prototype printed and it works perfectly.

Did you get any of his 14 shot mags for the chaser if you did those high rings will work great.

Following... I can't get enough of these SPA guns and there's some good info here.

Just a couple more steps to finish the Chaser conversion. I have the drop-block installed and a .35L CF tank attached to a 2200psi regulator threaded into the drop-block.
AR furniture arrives this week (butt and hand grip) that will finish off the upgrades then I will pull it apart and prep/paint the aluminum black to match the rest of the gun.
-
Looking good! Can't wait to see it finished.

I think about doing a bottle conversion on my .25 cal all the time, but I would get a Chaser tube like you have since it's a touch shorter than my Bandit tube, then I figure might as well get an entire chaser and the BR conversion, and then, and then.... ;D
-
I just have to figure out what reg pressure this gun likes, at 2200 PSI, it's doing 720 FPS, which is 160 FPS under what I want at 880 or down to 850 perhaps. I may open up the regulator and see if I can modify it al all or just shoot the gun down until I see 860 FPS and get another regulator for that pressure.

2200 PSI should be right on the money. Since you have a bottle and now a massive plenum, you could potentially turn it up to 2400 PSI and/or shim the inside of the hammer with a bit of lead for more strike. You could also maybe buy a Stormrider barrel from Wes to squeeze out a bit more efficiency. A .25 cal conversion would also help with power and efficiency.

I had thought so as well, that's why I went with the 2200 psi regulator BUT I didn't get the 860 fps I did when tethering from the bottle using my Altros inline regulator set at 2200 psi. :P
Yes, the plenum does help, 7 times in a row I got 720 fps... TWICE! Very happy about that but I still want 860 since my CPHP's LOVE that speed. Looks like I will follow your advice and shim the hammer spring to bring me up to 860.
Side note: I started at 3k psi and shot it down to 1.5k psi and got over 200 shots at 700-750 fps!!
"A .25 cal conversion would also help with power and efficiency." You are an evil man. ;)

I get 15 shots at 13 FPE (550 FPS 20.06 g H&N FTT) per 220b fill on a 50cc tube with an internal Altaros regulator set to 100b (so the tube volume must be almost nothing at this point). This means around 200 FPE per fill in 25 caliber, and that's using a Chaser hammer spring and no extra shimming or anything. Using a long barrel, like the one Wes sells for the .25 cal stormrider conversion there's probably 15 FPE available at the current reg setting and hammer spring.
Your bottle reg might not be as good as the Altaros inline reg, and you may need to set it a little higher to get the same output pressure. Sounds like it is at least very consistent even if the absolute pressure isn't as accurate.

I don't know Wes, do you have a link?
I don't know if I can adjust the chi-com regulator, it's listed at 2.2k.
I have the B. Staley oring mod that I'll remove too, just to see if that changes anything.
Ahhhh, I have a Stormrider hammer spring in it.

Wes is the proprietor and easy to do business with. Eventually I'll be converting my Stormrider to .25 cal, but sending in my old .177 stuff as a "core charge" for the .25 cal parts. Keep the Stormrider spring in there, the Chaser spring is only good for tuning for low power.
How much does the rig weigh now?

I definitely need a better .177 barrel, never ever had a .177 that shot well, it's the holy grail for me! I have 2 guns chambered for .25 so a Chaser in .25 would be a down-the-road project.
I'll weigh it tonight since I'm pulling it apart anyway.

My .177 Chaser Rifle barrel is very accurate, I just don't care for handling .177 pellets. Even .22 cal pellets are on the small side.

Nice! That's just a few oz heavier than my Stormrider!

Made an SSG this morning, very happy with this version.
Might tweak it a bit, but it does what I want it to.

Also printed different internals for the moderator, much better than the standard internals.

I am in South Africa, shipping would probably kill the idea.
Sadly I am also not set up for production of anything like this, made it using hand tools, do not have a lathe.
I am sure there are many guys on your side equipped to make something like this very easily.
Happy to share the dimensions of mine if that will help.

I am sure there are many guys on your side equipped to make something like this very easily.
Happy to share the dimensions of mine if that will help.
Yes it would, I do know a few machinists, but I'm not one myself.
Here you go...

Made an SSG this morning, very happy with this version.
Might tweak it a bit, but it does what I want it to.

Also printed different internals for the moderator, much better than the standard internals.

I really like the SSG, I would buy one from you.

Nice! All I need is someone to print out the keepers, I can turn the rest.
-
Can share the .stl file for the 3D print if that helps.
Or else add the dimensions for the print.

I haven't moved on to 3D printing yet so another person would have to make the keepers.

David... I may be interested in one of these if you can get them done.
-
Me too. I talked to a buddy of mine that does machine work to see if he's interested. Haven't heard back from him yet.
-
I could use it in my CP1/CP2/PP800 carbine.
-
I can't imagine how many shots I might get from my hpa conversion if I could get rid of the hammer bounce.
-
Here's what I got with my little .177 build. Nice little curve.
I think the SSG would flatten it out a bit more.

I've got 13ci tank on mine regulated to 800 psi. It's already getting 150+ spitting 7.5s at 740 fps.

Can someone source the parts? The sleeves will be the tough ones.

Are you referring to the outer 7mm steel sleeve?
If so, that is a quick lathe job if you have access to one.
I don't, so had to do mine on a drill press, slow speeds and lots of patience.
Used part of a 7mm bolt for it.
The inner part is a 4mm bolt with the head cut smaller to size and the thread removed on the middle part.
Attached is the .stl for the printed part.
I used PETG, 0.16mm laser height, 80% infill, normal PETG print settings outside that.
Maybe you can get someone to print you these.

I will do some tests over the weekend to see how it affects velocity and shot count vs. the standard setup.
It will still only be CO2, sadly getting the parts to convert to HPA are not that easy to find locally.

Yeah, not doing that, that's why tube exists. I'llook through my rack and see if I have any small enough to ream.
Yes, I have a lathe and other metal working tools but no CNC, scratch fab takes too much time vs stock/mod.

I got the carbon fiber tubes and cut one down to fit the HPA Chaser, it significantly tightened up groups. I was able to get 11 bullseyes in a row on the 10m target from a rest.
Very Impressive! ;D

It did for me too. I'm glad I ran across that video. I'm not sure where this originated, but it's a great accuracy mod that doesn't break the bank. I just got 2 more tubes in this week. I've got a couple of other guns to do.

Do you have a link to the video you are referring to please?

It's in this post.

Thanks, I like it.
Now to find a tube locally of course.

Looks good too!

Bit of testing this morning - nothing scientific, just a bit of fun.
First some shot strings over the chronograph to see what the difference is shooting without, and with the SSG.
Started each string with a fresh CO2 canister, 10 seconds between shots (the canister still cooled down significantly during the string which probably had some impact as well).
Shooting at 20m.
I stopped the string the moment a shot dropped lower than the group I was shooting, not counting that shot as part of the useful string.
The SSG flattens the curve out a bit and gave me 7 extra accurate shots (less than I hoped it would, but still an extra magazine's worth of shots per canister).

Then just some 7 shot groups with different pellets I have here, shooting from the magazine since I do most of my shooting that way.

Thanks, am quite happy with the little gun’s accuracy.
Took care of a few starlings not respecting my figs earlier today, CP2 is perfect for that.
