AEA Varmint hissing sound when bolt pulled back

[MarksmanPete]

So my brand new aea varmint came in I already noticed this hissing sound Im 99.9% this aint normal take a listen to this folks.

I make them from peek and Ti rod. They must be burnished in your gun, it's very hard and seating takes time. PM for details.

Fwiw, pei is not a crap product, just a bad application here.

Delrin is actually cheaper but robs power from the hammer to unseat.

Peek is the better choice but is more expensive.

The AEA line is what it is. Cheap and powerful. Nothing is for free though. The action/hammer are excessively sprung to make a lot of power, able to crack the valve at higher pressures unregulated. To tune down, it gets choked in the transfer but the valve takes the same hit every shot, high or low tune. PEI just doesn’t have the impact strength to be able to do that with a smaller pin. A pin with an upset to distribute the force would be better but again, cost.

So don’t beat on AEA or PEI too bad, at the end of the day, it’s just a poppet/stem. Easily made with minimal tools. And in that platform, pretty easy to change.

After my few attempts at making poppets from pei, I could not and would not recommend it for use as one in airguns. Point blank. Nobody needs beating up over it, it just should be echoed to heed caution using this material in this particular application (poppets) as its easily fractures/cracks.

It can be done but I had to cage it for longevity and it still chipped on the valve face after a while.

Yea, I mean, don't get me wrong when its working, pei cracks off the valve easily, the thing is, itself also cracks so easily, I wouldn't trust it long term as a poppet except in very very low power guns that still run large ports for lower lift conditions...even then.
