.22 cal. Marauder Rifle fill pressure 2605 psi

[HillGSA]

Is there any spacer to keep the depinger forward of the gauge block?.... How large is the hole in the depinger?.... Which way is it installed, and is there a chamber in the large end?.... Just visually it looks like the volume downstream of the depinger is pretty small for a 25 FPE gun....

- The spacer is built in.
- Larger opening against the gauge block.
- There is an open chamber.
- During testing, with the de-pinger installed in my .25 cal. Marauder Rifle; with the stock gauge block, the stock chamber inside the valve body, and shooting 25.39 grain pellets - max fps was 980 or 54.16 fpe, and with no ping. With a higher flowing valve assembly, if feel like the fps would have been even higher. Also, since 980 fps is already faster than I want to shoot pellets (transsonic, supersonic, etc.), I saw no need to test without the de-pinger installed.

Since the topic of de-pingers seem to come up often, a while back I decided to make a video and post it on youtube. This is my .22 cal. rifle shooting 25.39 grain pellets in a range from 868 - 918 fps, and with no ping. Only the muffled report of the rifle discharging can be heard.


Many of these same de-pingers have been sold, and with no complaints.
They work with all the Marauder Rifle calibers.

Also, another configuration is available for the smaller pressure tubes such as the Discovery Rifle, Marauder Pistol, Challenger Rifle, 1720T Pistol, 1701P Pistol, etc. (see pic).



Thanks,

Hill: I'm a newbie to these PCP guns I just bought a marauder 2 days ago. What sort of gauge are you            N u.  Using that you are able to determine exactly has much pressure your getting at each shot.

Here is a pic of the test rifle;

Very interesting results with that pressure level!

Wonder the results with this kit plus bstaley mod

I like your thinking.

Let me know if you want to try one

Most don't seem to have a problem. There are some videos on youtube you can look over before making a decision - like this one;





To add;

Once the kit is installed, the starting settings are simple - and are as follows;

Set hammer throw ( 1/8" wrench ) to 0 ( fully CCW )
Set hammer spring ( 1/4" wrench ) to 0 ( fully CCW )
Velocity screw ( 5/16" wrench ) will be preset to fully open ( 5 CCW ).

No worries about the settings moving or "self adjusting" and altering the shot string.

The barrels inlet port remains stock, so no worries about drilling it out.

I watched the video and I think I could get all apart, but putting it back together would be a problem...

Guess mine will stay factory...

Maybe you could have a friend help? Either way, just let me know if you change your mind.
