Made one up and thought id post my findings. I did open up the valve and barrel port on my rifle, so your results may vary.
The gun was tuned to shoot jsb 15.89 at 900 fps. I was getting 34 shots before falling off the reg at 110-115 bar. After the addition of of the ssg I picked up 10 extra shots. 44 at 900 fps before it falls off the reg.
Haven't modded the stock yet. But its pretty thick in that area. I dont see it protruding out the back side much if any when cocked.

Very nice shot addition.
-
It still amazes me that not one single manufacturer has implemented the SSG devise on any of their guns. Super simple devise especially if it were part of the original design. Nice execution on the DAR.

Could you share what parts you used?

Cant remember the size of the screw. But its just a flat t nut on one end and nylock on the other. Hole drilled in the factory spring adjuster. Spring is an 1 1/2 from McMaster Carr. Part # 9434k121

Agreed Hobby,
My RAW HM1000x gained at-least 50% more shots using (.22 cal.)18.13 JSB pellets at 920 fps with an SSG and porting mods.
In RAW's defense, they are marketed as a High Powered airgun; adding an SSG option would require them to confuse their established message and completely re-tune rifles before shipping.
However, the SSG would remove the negative "Loudness/Inefficient Tag" which follows their offerings.

Nice work, Rod. 8)

In my experience the SSG is an excellent device. Substantial increase in shot count.
-
Brilliantly simple!

Rod, thanks for the parts info.
Will the end cap/adjuster still be useable if the ssg is removed?

Absolutely. Just a small hole in the center of the end cap.
If you havent, the link Nevreloader posted is a must read.
-
this is great, would love to see a pic with the stock on, curious how you modified the stock to get that to fit?
-
Here you go sir.
-
When doing an ssg this way do you grind the threads off most of the bolt so it's smooth and does't drag on the end cap?
-
I do. Generally I go at it from the other direction and instead use a piece of round stock and just thread the portion I need. For example, 3/16” rod can be threaded directly to #10-32.
-
I have it pretty much set where i want it now. I'll probably sleeve it with brass hobby tube.

Help me understand what id going on in the pic. Is the rod protruding out the back after it has been cocked ?

Yes... a normal hammer is in free flight once the sear is released. With an SSG the hammer has a controlled stop. The hammer flight is limited to the length of the rod.

Correct. The spring is captured and partially compressed by the rod. Preloaded so to speek.
It keeps spring pressure off of the hammer after its been released and prevents hammer bounce.
