Can someone educate me on HPA conversions because I’m woefully ignorant about the process?
I think it’s best if I give you all my understanding of what occurs, which will no doubt be so far off the mark it’s not funny… then everyone can weigh in and please set me straight.
An Apache cylinder head would be needed, something air activated in the absence of a sector gear and tappet plate?
GBB rifle or pistol conversion
Pretty much replacing the fill valve on the gas mag with an HPA adaptor and you’re good to go as far as the blaster’s concerned? Is it really that easy?
AEG conversion
Cylinder and all associated airseal components, gears, motor and trigger removed from the gearbox shell and replaced with an aporopriate HPA engine?
How is the delivery of high pressure air triggered, and is the original trigger replaced by one that comes with the kit?
So basically a bare gearbox shell, t piece, inner barrel and receiver shell is pretty much all the OEM parts you need for an AEG HPA conversion?
Are there any limitations on the style of gearbox that can be converted? Obviously V2, V3 etc would be catered for, but how about weird gearbox designs like a P90 for example?
Like I said, I’m dumb as a box of hammers about HPA.
I am blissfully ignorant to HPA, but I have a limited knowledge of it.
Gbb you can replace the full valve with a hpa tap.
Alternatively you can just fill a green gas mag with HPA at the right pressure… don’t ask me what it is, or what nozzle you need to make up.
As for making an AEG to HPA you are swapping out the cylinder and nozzle assembly for an engine, and an fcu controls the trigger and selector functions usually in a circuit board package similar to a mosfet, and another board for programming usually would live in the battery area.
As for nozzle most will glue on a tip to suit the tpiece, or change tpiece and attach suitable nozzle tip.
Aside from that you need the ability to not call hits and think it shoots further and more accurately than it does and you are goood to go!
(It’s okay some hoa owners are normal people and good sports it’s a joke! )I
I did see a fellow at a field with a gbb rifle, that had a mag adaptor that took a hoa line, and the normal AEG m4 mag went into it… seemed like the best way to adapt HPA to a gbbr.
It did make the mag sit about three inches longer overall… and looked a bit silly… but any blaster with a line hanging out of it looks a bit silly I guess.
Can you pester them if you see them again? See if it has fitment issues?
If they slot it into the mag well and the mag latch fully seats or if its not? Is there a bur developing on the latch slot?
what gun they are using (more specifically the upper) when did they buy it? What rendition they think it is? And could u get some pictures if possible?
