Toilet paper test
Does this mean I have a leak where the gold washer (breech/valve) is?

Paris sent his LDC in two packages to prevent any shipping complications. The outer shell in one box and the actual LDC in another. Paris LDC is 1.5 inch in diameter and 8 inches long. Neil’s LDC is 1.5 inch in diameter and 6 inches long. With the .25 STD, I highly recommend at least 8 inches long. Neil is in the process of making me a new one that is 2 inch in diameter and 8 inches long. I need this gun to be really quiet. I think Paris and Neil’s LDC will get the job done. I think Paris’ is cool because you can slip off the cover and clean the inside if needed.
Overall length of the with ParisD LDC is 37.5 inches. Which I don’t mind because I am shooting inside the house and it is sitting on a Caldwell Deadshot field pod. If I need to take it outside or to the range I can always unscrew it.
Here is Paris 8 inch long next to Neil’s 6 inch. In reality, Paris’ LDC is really 8 1/2 inches because of the screw on section. Neil made his right into the LDC so it is hidden and screws on flush with his custom shroud.
What a piece. Did you get a separate package for it? how it compares to NC’s shroud? It must make the bullpup as a long rifle now.
Wow. Nice. Hey that’s not making up for any inadequacies in any other areas is it? 😆
Daaaaannnnnnggggg! That’s purdy! Which end do you blow on? :whistle:
Hi Donny !
I found a bunch of soft Cu washers used in district heating flow-meters and smaller valves. Those are 7.8 mm in diam, 1.6 mm thick but the hole is just 4mm. Is that too big a hole ? If it´s too small that´s easily fixed though.
I checked with the supplier and those same washers can be ordered even without a hole for “blind washers” when pressure testing and so on. Could that be an alternative ?? Those can be drilled to a needed hole dimension.
There are also PTFE “crush” washers (can be used once and need to be replaced every time the joint is opened again) but since those cost practically nothing it doesn´t much matter.
Tip for those who are having trouble removing the brass ring in the breech. I removed the the set screw and placed a small screw driver through it and pushed one side of the brass as far out as I can. holding that in place, I then took a small allen key, put it through the back and pushed the opposite side of where the screw driver is and it popped right out. I’ve been struggling with this all morning and this was the only method that worked without damaging it. Others had no problem just tilting it out. Mine was stubborn.
Thanks Hemn and WM.
You only need to remove the rear bolt/mag assembly to change you breach o ring.
If you cut down a 1.5mm allen wrench so the right angle part is only a 1/4 inch long you can use it to remove the grub screw under the forward breech retaining the brass bush without removing the forward breach assembly.
Can I take the barrel and breech off without degassing to change that O ring?
Yes,,,, for sure … taking off the barrel doesn’t need to degas the gun… expect the air gauge and regulator… if you ever go for these parts that directly tight with the air reservoir like Reg and air gauge,, you should degas the gun…

Dude!!!!!! 😯
Don’t you just love it when you think it’s this one thing that is difficult to fix and it turns out to be something really simple?
Yeah, me neither. 👿 👿 👿
Well on the bright side, next time you will know to check the probe o-ring first when the tp goes flying. 😉
