Sorry for the lack of knowledge on the subject, but what is a peek poppet and what does it do?

PEEK is a hard plastic that is easier to knock open than most other common poppet materials like Delrin or nylon, which is beneficial when:
1. Seeking to increase energy. For example, enlarging the valve throat makes a valve harder to knock open. Switching to a PEEK poppet may offset the difference without having to use more hammer spring tension or a heavier hammer.
2. Seeking to maintain the same energy level but improve the gun's shot cycle. For example, a PEEK poppet may allow you to use a substantially lighter hammer and/or less hammer spring tension. The result being a snappier shot cycle with higher efficiency...more shots, less noise, and a more pleasant firing cycle with less vibration.
3. Or some blend of both #1 and #2
However it requires a very high quality surface finish or it is likely to leak.

Very interesting, thanks for the info. I’ll have to do some more research into PEEK, haven’t ever heard of it till now.

I saw some people were trying different barrels like the Troy Hammer barrels, but has anyone (that you guys know of) ever tried to adapt an FX barrel to the avenger?

I thought about it... However FX uses a liner/barrel system and those liners in the same caliber as the avenger have much smaller outside diameter than the avenger barrels. You would have to to slip a piece of steel tube over the liner, epoxy it in place, and then have it machined down to fit tightly. But that would come with lots of problems. I just ordered a TJ barrel blank and had it machined to fit my avenger. Much better alternative in my opinion than an FX liner.

Avenger barrels are 11mmOD so not enough room in the Avenger receiver. I've owned both but I don't like the fx liner system. Some shoot great and some do not.

Fair enough, what does a TJ blank cost normally? I’d imagine it changes with length and caliber choice.

I believe the most powerful one I've heard of is AE Sweede tuned one for his buddy into the low 40's.

The avenger ones, at least the newer style ones, I'm finding quite easy to make. I pressure test each one before sending them out and have not had one leak yet. I have even stopped the fill with less than 1000psi to check it at lower pressures. They're not a flat on flat seal like the older style poppet.
To add to this, if anyone is still has the old style flat valve / poppet with the raised lip, I cam modify that to take a new or even an enlarged poppet.

The older style one is just a cylinder shape that sits over a flat or slightly raised hole. The new style poppet sits in a beveled hole and seals by using the edge of the poppet pushing into the beveled hole.
The black one is my PEEK replacement next to the OE delrin one and an old style popped but made from white PEEK made by Dark Charisma.

Yes. It's a centralizer device to keep it directly lined up with the port, plus the spring pushes on them.
