Bottle clamp / bipod mount for AS392HPA
« on: January 15, 2023, 01:46:29 PM »
Thanks to Pellethuntr for printing this bottle clamp / bipod mount for me.  The bottle was previously only supported by pipe threads.  I bought a cheap picanttiny mount intended for a 1" scope tube and replacement longer m4 fasteners.  The cross bolt is a binder bolt in anodized aluminum. The bottle feels much more secure and I think I will enjoy bench shooting from the bipod instead of a bag.

What adapter are you using to go from the tank to the air source threads? I have one I want to convert too.

Eddie,

I had this drop block machined and then used an adapter that has 1/8npt threads.  Mac1 sells an adapter like this blued (mine was stainless).  The OEM drop block doesn't drop far enough to clear a 2" bottle.  I used a long set screws into the valve to act as a stud and then assembled it with a washer and nut.    Let me know if you need any other details or if you have any questions.

This is what I have. The red piece on the end was in the gun when I got it. It leaks around the red part when I pressurize it though.

Eddie,

There is an o-ring down in the female portion of the OEM air source adapter.  It is challenging to replace, but it should seal if the o-ring is good.  With that said, I replaced the o-ring prior to the HPA conversion that deleted those parts and I was unsuccessful in getting an 88g CO2 cartridge to seal.

Eddie,

Here are the two o-rings that potentially could be the source of your leak.

Thanks! I don't see an o-ring inside of mine, so that could be the issue.

It's a really clean build that's for sure. Hopefully I'll get around to finishing mine one day.
